G.3 Resistive sensor measurement function
Rated maximum voltage in common mode: 60 VDC or VAC.
G.3.1 Resistance (TC622, TM612 and TM630)
The resistance measurement function is obtained by configuring the device as follows:
Sensor: PT100 and Unit: Ohm for the 400 Ohm gauge.
Sensor: PT1000 and Unit: Ohm for the 3600 Ohm gauge.
Gauge Scope of measurement Resolution (min) Precision / 1 year
400 Ohm 0 Ω to 400 Ω 10 mΩ 0.012% R + 10 mΩ
3600 Ohm 0 Ω to 3600 Ω 100 mΩ 0.012% R +100 mΩ

Temperature coefficient < 10 ppm R/°C from 0°C to 18°C and from 28°C to 50°C.

Automatic wiring diagram detection: 2 wires. 3 wires or 4 wires.

In the 2-wire assembly, the measurement includes the line resistances.

In the 3-wire assembly, add the line resistances imbalance.

For negative temperatures. use the value displayed L and not its absolute value.
Temperature coefficient: < 10 % of precision/°C from 0°C to 18°C and from 28°C to 50°C.
The above precision is given for a 4-wire connection to the temperature sensor.
You should also take into consideration the actual error of the temperature sensor used. as well as the conditions of its
setup.
