Installation instructions
The Scale app uses Bluetooth pressure monitoring sensors.
After calibration, it shows the gross weight of the truck.
1
Installation of sensors
The sensors must be connected to the pressurized air of the suspensions. Choose easily accessible places to install the sensors outside the frame and close to the cabin. The sensors can be installed behind the gauges in the dash or under the hood. The trailer sensor can be installed near the gauge or on an air line going to the airbag suspension. Use air hose extension with wall mount if needed. The sensors are weather resistant and should not be in a metal box.
