RTD_TYPE? IEEE-488 RS-232 Sequential Overlapped
This command returns the Resistance Temperature Detector (RTD) sensor type being
used for RTD temperature source and measurement.
Parameter: <None>
Response: <value>
where <value> is one of the following:
PT385_100 100-ohm RTD, curve a=0.00385 ohms/ohm/°C
PT385_200 200-ohm RTD, curve a=0.00385 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
PT392_100 100-ohm RTD, curve a=0.003926 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
Example: RTD_TYPE?
PTJIS_100
This example indicates that the RTD sensor type is a 100-ohm RTD
with curve a=0.3916 ohm/°C.
