Keithley 2001 User Manual

IEEE-488 Reference
4-160
Programming example Suppose you are using an SPRTD that has been calibrated for subrange #2 above that is calibrat-
ed for measurements between 24.5561 and 273.16K. Model 2001, however supports only
SPRTD temperatures down to 83.805K, so temperatures below this value will be reported as an
overflow even though the SPRTD is capable of measuring lower. The calibration certificate lists
A2, B2, C1, C2, and C3 as the calibration coefficients. You can set up Model 2001 for this mea-
surement as follows:
1. Set the temperature sensor type to FRTD (4-wire measurement) by sending:
:SENS1:TEMP:TRAN FRTD
2. Choose the RTD type as SPRTD:
:SENS1:TEMP:RTD:TYPE SPRTD
3. Set the RTD sensor 0˚C resistance value:
:SENS1:TEMP:RTD:SPRTD:RZER <R_zero>
4. Set the A4 coefficient to the RTD certificate value for A2:
:SENS1:TEMP:SPRTD:A4 <certificate_A2_value>
5. Set the B4 coefficient to the RTD certificate value for B2:
:SENS1:TEMP:SPRTD:B4 <certificate_B2_value>
Note that the A7, B7, and C7 values will not be used for this sensor.
6. Change to the temperature function, and begin taking readings.
