same module.
4. Press Sensor Settings > Sensor, specify the type of transducer probe used as 2-wire or 4-wire RTD.
Then, selects the nominal resistance, R
0
, as PT100 (100 Ω) or PT1000 (1000 Ω). R
0
is the nominal res-
istance of a RTD at 0 °C.
5. Press Use as ref to enable (On) or disable (Off) the currently selected channel to be used as the ref-
erence channel for subsequent thermocouple measurements that specify an external reference source.
