remind: First of all remind the speed problem, the meter does not have the speed inaccuracy, as long as the alignment is well calibrated, it will be accurate.
The meter has 2 speed lines, the blue and white bar is the phase line speed, and the thick line of the motor is connected. Or choose another white spare wire without copper, this is the hall signal connected to the hall of the motor. Hall speed and phase linear speed can only be connected to one.
If the acceleration speed is displayed as 199, then the Hall signal of the meter is connected to the phase line of the car. Need to putThe speed line is connected to the motor Hall line, Do not connect the phase line or the previous speed line, otherwise the speed will beRandom jumping 199 not allowedof. In addition, there is no Hall line in the front of the car. Don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t doubt the product when you encounter speed jumps. The products are the same. Others can do yours. The speed jumps are all wrong lines.
Monochrome screen voltage range 12v 24v 36v 48v 60v 64v 72v 80v 84v 96v. Can be customized 12v power supply 0-108v universal.
Color screen 48 60 64 72v optional. 48v, special voltage message is sent by default, or Wangwang informs the seller.
Applicable scope of the instrument:
Ordinary original two-wheel electric vehicles can be installed directly.
Refit electric vehicles, tricycles, and small lithium batteries. If the motor has gears, toothed high-speed motors, or thinking cars, 2-wheel balance cars, etc., the speed is normal when driving, but the speed will not be displayed when coasting. It can be solved with an external sensor.
Motorcycles, cars and other vehicles without Hall sensors can also be connected to an external speed sensor for speed measurement.The sensor picture is at the end of the page.
The picture below is an old model and is for reference only. New models are now released.
The above picture shows the instrument fixing bracket, which can be fixed and locked on the handlebar. If you need to install it on the handlebar, you can take one or two. Buyers are welcome to provide the renderings after installation, or provide other more reliable and suitable installation methods, and those who provide pictures will receive free shipping on the next purchase. The screw holes on the meter case are relatively small, so you can use scissors to drill larger.

<> Features:
Digital voltage（Over a hundred）Electricity, speed（Over a hundred）, Accumulate mileage（One thousand kilometers increased to one hundred thousand kilometers）, 123 gear display, driving time,Single mileage, Headlights, turn left and right. An external sensor can be connected.The screen is blue by default, which makes it clear during the day and night.
Buyer installation effect display
The picture below shows the modification effect of a separate display screen. You can also purchase a separate screen.
Sensor picture and installation reference.
In response to the requirements of the majority of modification enthusiasts, a meter suitable for modification is specially introduced. It is small in size and can almost be installed on a pedal electric vehicle.（The circuit board size is 8cm×5cm. The liquid crystal size is 5.7*3.6cm）
New weight launch:
Function, accurate voltage display, can accurately judge your battery voltage, error range, 0.2v up and down
How to look at the battery voltage "For example, if you are a 36v car, the voltage range is 31.5v-38V as the power supply range. You can calculate it like this. After the battery is fully charged, the voltage per cell will increase to 13.2v (in the case of full charge)）In this way, the number of battery cells is your current fully charged voltage number, n*13.2=full voltage number, battery undervoltage is 10.5v, so calculate, 10.5×n = voltage undervoltage value, n represents the number of battery cells
Hall speed display,（To be connected to the Hall line of the car.Hall line search method:There are 8 wires from the motor to the controller, the 3 thick ones are the phase wires, and the 5 thin ones are the Hall wires. The colors are red, black, yellow, green and blue..Can pick up fine yellow, fine green, fine blue,Don''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''t connect black red.）In order to display the speed accurately, the Hall signal from the motor to the controller is adopted, and there is no need to add a Hall signal. The instrument uses this signal and then combines the speed calculated by the wheel diameter.（There is a potentiometer under the meter to correct the display speed, the principle is to adjust the ratio of Hall pulse to the governor）So it is very accurate and suitable for all kinds of electric car modification,
Accumulated mileage, you can accumulate the mileage you have ridden, power-off memory, if the accumulated number is completed, the calculation will automatically start from zero（This time is relatively long）
Driving time, you can record the time you drive, not Beijing time,Turn signal indicator, headlight indicator, 123 gear indicator,Really achieve full-function display LCD instrument,The perfect substitute for mechanical watches.
The instruments are guaranteed, and each instrument is guaranteed for 100 days. It can be refunded within 7 days, replaced within 30 days, and repaired within 100 days.
