RTD_MEAS
Sequential OverlappedIEEE-488 RS-232
x x xx
(RTD Measure command) Selects the measure RTD mode.
Parameters: CEL (Celsius) (optional)
FAR (Fahrenheit) (optional)
Example: RTD_MEAS CEL
Measure the RTD temperature that is attached to the Calibrator RTD terminals, in
Celsius.
RTD_TYPE
OverlappedIEEE-488 RS-232 Sequential
xx xx
(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 (100-ohm RTD, curve α=0.00385 ohms/ohm/°C)
PT385_200 (200-ohm RTD, curve α=0.00385 ohms/ohm/°C)
PT385_500 (500-ohm RTD, curve α=0.00385 ohms/ohm/°C)
PT385_1000 (1000-ohm RTD, curve α=0.00385 ohms/ohm/°C)
PT392_100 (100-ohm RTD, curve α=0.003926 ohms/ohm/°C)
PTJIS_100 (100-ohm RTD, curve α=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)
USR_DEF<x> (RTD with user defined coefficients (x from
1 to 5)
Example: RTD_TYPE PTJIS_100
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)).
