4.5.6 Wiring
Note:
It is not necessary to connect analog inputs COM terminal to negative power supply.
Long wires resistance compensation
Process of compensation:
Short all wires to analog sensors at the end (replace sensors with shorting links).
Hold the compensation button on IGS-PTM through the hole in upper cover when switching IGS-PTM on.
Result of compensation will be shown in 2 seconds by flashing of POWER LED.
One flash and pause – compensation fail.
Three flashes and pause – compensation success.
Measured lead’s resistance is stored in EEPROM memory (separate value for each input) and is
subtracted from measured value when resistance measuring.
