(Resistance Temperature Detector Type command) Sets the Resistance Temperature

Detector (RTD) sensor type.

Before using RTD_TYPE, select RTD using the TSENS_TYPE command. After using

RTD_TYPE, select the output temperature using the OUT command. Changes in

temperature sensors changes the output to 0 °C. Once set, the Calibrator retains the RTD

type until power off or reset.

Parameters: PT385 (100-ohm RTD, curve α=0.00385 ohms/ohm/°C)

PT385_200 (200-ohm RTD, curve α=0.00385 ohms/ohm/°C)

PT385_1000 (1000-ohm RTD, curve α=0.00385 ohms/ohm/°C)

PT3926 (100-ohm RTD, curve α=0.003926 ohms/ohm/°C)

Example: RTD_TYPE PT3926

Set the RTD type to a 100-ohm type, using the pt3926 curve

(α=0.003926 ohms/ohm/°C). The resistance of 100 ohms refers to the ice point

characteristic, (the resistance of the RTD at 0 °C (32 °F)).
