)
• Connect a digital voltmeter (DVM) to
Tp 1 (signal) and Tp 2 (GND) on the elec-
tronics board OXS (g. 7-15).
• Adjust the measured signal to 3360 mV DC
(± 5 mV) utilizing the potentiometer R4 on
OXS board.
Having replaced the worn sensor, the board´s
output signal requires some adjustment.
Note!
Once the output signal has been adjusted
for a specic sensor, further changing the
potentiometer settings will cause incorrect
measuring results!
