Bicycle computer stg 15 functions setting. Correct installation of the cycling computer - everything you need to know about the setup. Cycling Computer Button Functions and Typical Operations

A bike computer is a very useful accessory that is very popular with different cyclists. Amateurs are simply interested in keeping track of daily mileage and other indicators, and for a bike computer it is a means of monitoring their training process.

But you can completely trust the data only if it is correctly installed and configured.

Types of bike computers

Also, the installation process may be slightly supplemented depending on the functionality of the accessory. So, for example, if cadence counting is provided in the cycling computer, then the sensors will need to be installed on.

Correct installation

It is best to start the installation of the bike computer from the top - with the base set to. It is on the mounting platform that the bike computer itself will be fixed in the future. You can install it either on the steering wheel itself or on the take-out.

There is no fundamental difference in this, it all depends on your own preferences. A small plus in favor of installing a computer to take away is that in this place the computer will be larger.

In addition, it may be necessary to turn the bike upside down and in this position there will be no pressure on the base.

The base is fixed to the handlebars with an elastic band. If its tension is not enough for the bike computer to be securely fixed, then you can additionally secure the mounting platform using double-sided tape.

If it's a pity to stain the steering wheel with glue, then you can just put a piece of rubber in order to prevent the bike computer from sliding on the handlebars or stem.

The next step is laying the wire, if there is one, of course. Before installing the bike computer on the bike, you need to estimate the length of the wire.

If this is sufficient, it is best to wind the bike computer harness around or on the front brake cable. In this case, there will be no need to fix it in many places and it will not interfere.

It is necessary to wind the cable up to the gorilla (the place where the front fender should be attached), and then stretch it to the opposite leg from the brake rotor.

If the length of the cable is small, then you will have to fix it on. It is important that it does not dangle or stick out anywhere. On the other hand, it is necessary to leave gaps in the area of ​​the head tube so that the steering wheel can turn freely.

The postings should be fixed in the following places:

1. On the handlebars next to the mounting pad;
2. On the handlebars next to the stem;
3. In the center of the stem;
4. Near the fork stem;
5. On the crown of the fork;
6. On a gorilla;
7. In the middle between the gorilla and the sensor;
8. Near the sensor mount.

With this frequency of fixing, the wire will be securely fixed and will not dangle. It is important to note that there is no need to fix the wiring on the head tube.

The final stage of installation is to attach the sensor and magnet. The distance from which the sensor and the magnet should be mounted should be specified in the instructions for the specific cycling computer.

The sensor should be perpendicular to the wheel, and the magnet should "look" straight at the sensor. If the magnet or sensor is deflected to the sides, then the speed and, accordingly, the mileage will be inaccurate.

The magnet should not be too close or too far from the sensor, within 2-5 mm, but this distance should also be specified in the instruction manual.

If a cadence sensor is provided, then it must be installed by analogy with the speedometer. The magnet should be mounted preferably on the left crank arm, and the sensor on the frame tube: either the bottom or the seatpost, depending on the model.

How to set up the cycling computer is described in detail in each manual. It is impossible to tell about some universal method and procedure for setting it up, since almost every model is individual.

The main indicator on which the correct setting of the bike computer depends is. You can find it out from the table below, it should also be in the instructions for the bike computer.

It should be noted that it is necessary to take into account not only the diameter of the wheel, but also the width that is installed. Indeed, often, its height also depends on the width. True, the error still exists.

The dependence of the width of the tire on its height is different for some manufacturers. For example, Schwalbe tires are slightly larger than Continental tires of the same size. It is almost impossible to take this into account in the table. Despite this, the error will be extremely small.

Those who need the most accurate speedometer readings can measure the circumference on their own in two ways. The first is measuring with a thread. It needs to be wrapped around the outer diameter, i.e. on the tread.

Second way. It is necessary to mark the point of contact on the asphalt and tire. Then drive exactly one revolution so that the point marked on the tire touches the asphalt again and makes a mark on it.

The distance on the asphalt between two points will be the longest circle. It is believed that the second method is more accurate, since the tire deforms while driving.

During setup, you will also need to set the date and time as standard. On bike computers, you will need to indicate your weight, height, age and gender. You should also not forget about the choice of units of measurement.

Outcome

Correct attachment and adjustment of the bike computer is the key to the accuracy of its readings. The article described the general installation and configuration procedure, which will vary depending on the specific model.

To fully trust what the bike computer shows, it is imperative to read the instructions.

1. Zeroing. Before starting the cycling computer, you must reset its previous parameters. To reset the readings of the cycling computer, it is necessary to remove from the slot for a short time the flat rechargeable battery located under the cover on the back of the display and insert it back into the slot.

2. Wheel circumference. The display will show the digits "2060", the first digit on the right will blink. The figures shown represent the circumference of the bicycle tire. For correct subsequent measurements of the parameters of the movement of the bicycle, it is necessary to set the wheel circumference of your bicycle. This can be done in the following main ways:

Select from the table;

Directly measure the wheel circumference;

To select the circumference using the table, you need to find its diameter on the wheel tire, for example "26x1.25". In the table, we find, opposite the given diameter, the corresponding circumference - 1953 mm and enter it into the bicycle computer. To enter numbers, press the right button in succession and set the desired value of the right digit in the circumference (in our case, "3"). Then briefly press the left button. The second digit on the right side starts flashing. In the same way, with the right button we set the second digit (in our case "5") and in the same way set the two remaining digits "9" and "1".

A second more accurate way to measure the circumference of a wheel:

Apply a thin but thick transverse line on the tire with white chalk (tires must be pre-inflated to normal operating pressure). Next, you need to sit on the bike and slowly drive in a straight line for more than one wheel revolution, so that the first and second chalk marks on the tire are imprinted on the asphalt or other hard surface (this operation is best done with an assistant holding you while driving). Next, you need to measure the distance between the two risks in mm on the asphalt with a tape measure and enter the numbers into the bike computer in the way indicated above.

Press the LEFT button on the bike computer display to select the value of the desired parameter, then press the RIGHT button to store the value (from 0 mm to 9999 mm). Press the RIGHT button to turn on the CM / H mode.

3.Installation of KM / Ch and M / Ch
Press the right button to select KM / H or M / H. Press the LEFT button to enter ready mode. Press the LEFT button to cancel and enter CLOCK mode.

4... CLK mode - Clock mode
In watch mode, press and hold the LEFT button for 3 seconds to select 12h / 24h. Briefly press the LEFT button again to select 12h or 24h mode.
Press the RIGHT button to enter the TIME SETTING mode, when the number of hours indicator starts flashing, press the LEFT button to change the hour value.
Press the RIGHT button to continue to set the minutes, the minute indicator will flash, use the LEFT button to change the minutes.
Then press the RIGHT button to switch to SPEEDOMETER mode.

5. Setting the Last Odometer Value
In ODO mode, press and hold the LEFT button for 2 seconds to set the ODO value, the initial value will be 0000.0.
When one of the digits starts blinking, press the RIGHT button to change the value, then the LEFT button to save and move to the next digit.
(After replacing the battery, the last parameter value can be entered in accordance with the value that was before the battery was replaced).

6. Resetting the ODO parameter
Press the RIGHT and LEFT buttons simultaneously and keep them pressed for 3 seconds to reset the ODO parameters.
This will reset the wheel size and range. The time will remain unchanged.

7. SPD - indication of the current speed(similar to the speedometer reading in a car)
The current speed is constantly displayed on the screen. The maximum possible value is 99.9 km / h, the accuracy is +/- 0.1 km / h.

8 ."+" "-" indication of the deviation of the speed from the average SPEED COMPARATOR
During the ride, a "+" or "-" indicator appears on the screen, which means that the current speed becomes higher or lower than the average speed during the trip.

Clearing Current Trip Values press and hold the LEFT button for 5 seconds. In this case, all parameters of the current trip - DST (Distance traveled by the electric bike during the current trip), MXS (Maximum speed value recorded during the current trip), AVS (Average speed value recorded during the current trip), TM (Total value by the duration of the current trip) - will be reset to 0.

The mode of scanning the parameters of the cycling computer and their display on the display screen, while the following measured parameters are reproduced: DST, MXS, AVS and TM (parameters are displayed alternately, the duration of each display is 4 seconds)

In order to switch to CLOCK MODE, press the RIGHT button.

Sleep Mode - Sleep mode
If there is no signal from the sensor of the cycling computer for 5 minutes, the display goes into sleep mode, only the clock is shown on the screen.

Freeze Frame Memory - fixing the readings of the cycling computer in this moment time and
To fix the readings of the cycling computer at a certain fixed time, you must press the LEFT button and all readings will be fixed. The display will show TM (Current ride duration) flashing. Using the RIGHT button you can go to other fixed parameters.
To exit the specified mode - press the LEFT button.

Assigning the buttons of the cycling computer
RIGHT button is used when switching between ODO, DST, MXS, AVS, TM, SCAN modes (DST, MXS, AVS, TM and CLOCK).
The LEFT button is used only to switch the fixed readings of the bike computer (Freeze Frame Memory)

Installing bike computer parts

1.Fasten the reed switch (magnet) in the form of a cylindrical post to the outer spoke of the front wheel. The transducer is mounted with a screw on it so that you can move the transducer with a little force along the spoke as you select the desired position. In this case, the end of the sensor, with the magnetic part, must face the reader, which is to be fixed on the plug.

2. Install the reader (stationary) of the cycling computer on the interior racks (feathers) of the bicycle front fork with Velcro and additional fastening with two plastic clips. If there is a disc brake on the front wheel, it is better to install the reader on the fork post opposite from the brake disc. When choosing the place of attachment of the reader, it is necessary to proceed from the fact that the distance between the end of the sensor and the reader during the rotation of the wheel should be within 0.2-0.3 cm (while the end of the sensor should move against the central part of the reader). After setting the distance, finally secure the sensor to the spoke and the reader to the fork. At the same time, when finally tightening the fastening plastic clamps on the reader and the fastening screw on the sensor, the distance between the reader and the sensor should increase to 0.5-1.0 mm. This will be the correct working distance between the sensor and the bike computer reader.

3. Secure the display mounting pad with Velcro and two plastic clips to the handlebar.

Before attaching the display mounting pad to the steering wheel, it is advisable to pre-lay the wire from the reader to the display of the bike computer in such a way that, for any turns of the steering wheel, this wire remains free and without tension. Further, the wire from the reader is additionally fastened with flexible plastic clips in the right places.

4. We fix the display of the bike computer on the mounting platform.

Computer installation (see manufacturer's manual / diagram)

Secure the table to the handlebars using plastic straps (or rubber bands) and a rubber pad. Secure the sensor to the fork using plastic clamps (or rubber bands), do not tighten them all the way and a rubber gasket. Then attach the magnet to the spoke of the front wheel so that the distance between it and the sensor is no more than 5mm. Place the cycling computer on the table (until it clicks). Raise the front wheel and spin it. If the indication appears, then the bike computer is installed correctly, if not, check the position of the sensor and the sensor. Then tighten the clamps and magnet fasteners. To avoid damage to the wire connecting the sensor and the stage, it is recommended to fix it in several places with electrical tape / tape and / or wrap it around the frame, brake jacket and fork.

2.1. Before adjusting, you must correctly measure the circumference of the bicycle wheel. This is the main parameter that affects the accuracy of the computer (speed, distance traveled).
You can do it yourself:
Method # 1. Position the front wheel of your bike so that the camera valve (where the bike pump is connected) is perpendicular to the ground. Make a mark on the asphalt exactly opposite the valve. Roll your bike forward or backward until the wheel completes one full revolution. Make a second mark on the pavement opposite the valve when it is perpendicular. Measure in millimeters the distance between the marks - this is the circumference of your bike's wheel.
Method number 2. On each bicycle tire (tire), the manufacturer indicates its diameter in inches or, less often, in millimeters. Below is a table of bicycle tire circumference according to size. The tabulated lengths may differ slightly from the real ones, since the tire pressure affects the diameter (and the distance traveled) of the wheel.

2.2. Before starting to use a new cycling computer or after replacing the battery for a FULL data reset, press the "Reset" button (1) (Fig. 1).
2.3. After using the Reset button, a test of all display segments will begin. Check if all numbers and letters are displayed correctly on the LCD screen (Fig. 2).
2.4. Press the button (2) "Mode" (Fig. 1) to stop the screen test. A blinking "KM / h" overhead and the value "s2155" will appear on the screen (Fig. 2).
2.5. Pressing the "Mode" button (2) select the desired speed measurement method: "KM / h" (km / h) or "M / h" (mph). Each press of "Mode" will toggle the value between "KM / h" and "M / h".
Attention. If you do not press "Mode" for 30 seconds, the bike computer will automatically exit the setup mode. To return to the setting, press and hold the Mode button for 6 seconds.
2.6. Press and hold the "Mode" button for 3 seconds - until the number 2 starts blinking in the value "s2155". The computer will switch to the mode of entering the circumference in millimeters (see p.2.1.). The initial value (default) is 2,155 mm. for 28 ″ wheels. By quickly pressing the "Mode" button, set the value of the first digit. It will blink and change its value from 0 to 3 each time it is pressed. To enter the next digit, hold down the "Mode" button for 4 seconds. Subsequent digits can change their value from 0 to 9. To save the entered values, press and hold the "Mode" button for 6 seconds or more.

The following are screenshots of the computer screens during setup.

Although I planned to get hold of a bike computer, I didn’t bother to buy it in a year, I got by with a phone with GPS. Now I accidentally bought it, and decided to write a review for you, well, and a little for myself, so as not to read the instructions once again ...

The bike computer came without a track by a simple parcel, the declared price on the postal package is $ 2, inside the package there is a branded box with a window from which the "computer" itself is visible (not visible in the photo, but the screen has a protective film):


under it is a little white box, in which:
- instruction;
- a cheap magnet with a knitting needle;
- 6 black screeds;
- wiring, on one side of which there is a reed switch, on the other - a bicycle computer mount.
No dangling, like an enema, but it is reliably filled with black glue, probably this is the modern epoxy.


The bike computer mount can be positioned vertically or horizontally, but on the back side (where screws ) double-sided tape is already glued, if you (like me) want to attach it to the steering wheel, you will first have to peel off this tape. I would rate its quality as low, but there is no need for glue - this tape can be replaced with a piece of rubber.

well, if later we want to turn the mount, we will have to remove the ties, peel off the tape from the bike, from the mount to get to screws !

Unscrew screws , turn the mount 90 degrees and "snap" it to the holes:


then screw in screws and sculpt the scotch tape back:


We click "computer" - we get something like this:


It is removed with a slight upward movement with a simultaneous light pressure on the pipette below.

The sensor is symmetrical, maybe you know where it is in front, where is the rear, but I attached the forks in front, so that if it accidentally touches the magnet when moving the bike forward, it receives less damage. There is also double-sided thick tape there, but I have not yet glued it, because may need to be rearranged.

Magnet inside the spoke mount:

The bike computer itself with a diagonal of 6 cm (the view from below is better, perhaps on a new battery it will be more contrasting):

The battery is not included in the package - it's good: the price is lower and a new battery will often be better than the stock one. At worst, you can pull it out of the motherboard, I pulled it out of the almost unused flasher bought a year ago into the knitting needles - for the first time that's enough, the backlight is working and the indicator of the dead battery is not on yet.
When connecting it, I slightly bent the side contact - just in case for better grip.

More detailed description functions can be found in the instructions, I will describe what I learned and, perhaps, will supplement as I study.

The buttons are labeled from left to right: UP, MODE, SET.

The MODE button, when pressed briefly, switches between three display modes:
- main (DISPLAY);
- (INQUIRE);
- (Up & DOWN).

Long pressing the SET button from the first two modes will allow us to set the initial values ​​and settings.
You can change the values ​​using the UP button in a circle, and switch between the changed values ​​with the SET button. You can exhibit:
- units temperature(my sample measures the temperature with an error of about +3: at 4 degrees it shows 7),
- units time,
- current time,
- wheel circumference (CIRC) - according to the table, depending on the diameter of the wheel and the thickness of the tire (for my 26 "wheels and 1.5" semi-slick - this is 198.5),
- units distance,
- initial value distance traveled(ODO),
- initial value total driving time(RAT).

As you can see, this device measures the temperature (from -10 to +50 Celsius or Fahrenheit equiv., Sorry, without the possibility of calibration). If you do not ride or press any buttons, the cycling computer goes into "standby mode" and displays the time.

The backlight turns on when you press the buttons in the dark (you see, there is a light sensor) or when you press the MODE button for 3 seconds, then it goes out; if you hold it down for 5 seconds, the backlight will not go out until you hold down the MODE button again for 5 seconds.

A short press of the SET button from the first two modes will show us the stopwatch instead of the time on the second line. Start / pause - UP button, reset - SET, MODE button will hide the stopwatch, but will not stop it and you can return to it in bulk. If you remove from the base (do not ride) in stopwatch mode and do not press any buttons, the cycling computer will enter "standby mode" with the stopwatch displayed.

Also, there are functions for measuring the distance and time "in one direction" and "in the other", they are presented in the third mode, they can be reset by long pressing the UP button, while the total driving time (RAT), total mileage (ODO) and the current time are not reset.

And this is only part of the instructions. It can still "freeze" the values ​​on the screen, blinks with something at a speed of more than 20 km / h, after 300 km it reminds you to fill in oil, after 500 km it reminds you to carry out maintenance, shows with arrows, above whether the current speed is average or below and can show a low battery icon.

P.S. the package says “SD-563 A", In the instructions -" SD-563 B».

About buying. It all started with the purchase of cycling shorts: I ordered some, the seller sent others, and even used some kind of postal service from Aliexpress to send them. At first, I received a partial moneyback due to the discrepancy of the panties (fortunately, the size was the same, but the type of product and the seams were noticeably different), and a couple of weeks later I found a coupon from Aliexpress for a $ 3 discount for any purchase with an apology for the delay in mail in Tallinn! The date of purchase is still visible on the screen, from which we can conclude that the product has been going on for almost 6 weeks.

I found a review of almost the same device, the difference is, perhaps, in the absence of backlighting and the design of the screen - - the modes are very well described, good photos.
Another review - - with pictures of the insides!

If you have installed everything, sat down, drive, and the speed is at zero - do not rush to turn the reed switch and turn the magnet: check if the wheel diameter is correctly set - the "CIRC" setting, after setting the time!
