(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)

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)).

(Resistance Temperature Detector Type Default command) Sets the default Resistance
Temperature Detector (RTD) at power on and reset, which is saved in the Calibrator
non-volatile memory. (While saving configuration data in the non-volatile memory, a
period of about 2 seconds, the Calibrator does not respond to remote commands.)
