Connect the digital multimeter with the connecting line of the analog interface. Set in
menue Set oft RTM the operating mode Continous. Take the calibration stick into the
RTM at the receiver-side.
The voltage value at the analog output has to be between 2,25 V and 2,75 V.
The exact voltage can be calculated with following formula:
Calibration stick value in % : 100 x 5 V = voltage
E.g.: 51,5% : 100 x 5 V = 2,575 V.
In case of error:
- Ceck the connecting line with ohmmeter.
Error still present:
- Replace the interface circuit board.
