Description of the test unit

The device (R58/37, R58/117 V01 or R58/117/1) contains an electronic calibration unit for each of the sensors SI and SII of the double wheel sensor. The activation of the internal sensors are indicated by LEDs. The power supply of the testing device is provided by a built-in 12-VDC Ni-Cad battery (1.2V x 10).
