This command sets the Resistance Temperature Detector (RTD)
sensor type for RTD source and measure. Normally, before using
the RTD_TYPE command to select the RTD type, use the
TSENS_TYPE command to select RTD mode, and afterwards set the
output temperature using the OUT command, if applicable. A
change in temperature sensors sets the output to 0 °C. Note that the
SPRT can only be used to measure signals, not source them.
Parameters:

ohms/ohm/°C
PT385_500
500-ohm RTD, curve a=0.00385
ohms/ohm/°C
PT385_1000
1000-ohm RTD, curve a=0.00385

ohms/ohm/°C
PTJIS_100
100-ohm RTD, curve a=0.003916
ohms/ohm/°C
CU10
10-ohm RTD, empirical curve
NI120
120-ohm RTD, empirical curve
YSI_400
YSI thermistor curve
OHMS_HIGH
4000 ohms range
OHMS_LOW
400 ohms range
SPRT
standard PRT with user defined
error coefficients, only available
for measurement
USR_DEF<x> RTD with user defined custom
coefficients, where x is the curve
number and ranges from 1 to 5,
i.e. USR_DEF2 for curve 2
Response:
<None>
Example:
RTD_TYPE PTJIS_100
This example sets the RTD sensor to a 100-ohm
type, using the PT3916 curve (a=0.003916
ohms/ohm/°C). The resistance of 100 ohms refers
to the ice point characteristic, the resistance of the
RTD at 0 °C (32 °F).
