Keithley 2001 Calibration Manual

Calibration
2-20
16. Perform user AC calibration by sending the following
command:
:CAL:UNPR:ACC
Note that the AC calibration phase will take about six
minutes to complete.
17. Check for AC calibration errors by sending the follow-
ing command:
:SYST:ERR?
NOTE
The following steps perform the low-level
part of the calibration procedure. Use only
the indicated calibration values for these
steps. Be sure the instrument completes
each step before sending the next calibra-
tion command.
18. Connect the Model 2001 to the calibrator using 2-wire
connections, as shown in Figure 2-3.
19. Program the calibrator to output 20V AC at a frequency
of 1kHz, then send the following command to the Model
2001:
:CAL:PROT:LLEV:STEP 1
20. Program the calibrator to output 20V AC at a frequency
of 30kHz, and send the following command to the Mod-
el 2001:
:CAL:PROT:LLEV:STEP 2
21. Set the calibrator output to 200V AC at 1kHz, then send
the following command:
:CAL:PROT:LLEV:STEP 3
22. Set the calibrator output to 200V AC at a frequency of
30kHz, then send the following command:
:CAL:PROT:LLEV:STEP 4
23. Program the calibrator to output 1.5V AC at a frequency
of 1kHz. Send the following command to the Model
2001:
:CAL:PROT:LLEV:STEP 5
24. Program the calibrator to output 200mV AC at a fre-
quency of 1kHz, and send the following command to the
Model 2001:
:CAL:PROT:LLEV:STEP 6
25. Set the calibrator output to 5mV AC at a frequency of
100kHz. Send the following command to the Model
2001:
:CAL:PROT:LLEV:STEP 7
26. Program the calibrator to output 0.5mV AC at a frequen-
cy of 1kHz. Send the following command to the Model
2001:
:CAL:PROT:LLEV:STEP 8
27. Set the calibrator output to +2V DC. Send the following
command to the Model 2001:
:CAL:PROT:LLEV:STEP 9
28. Program the calibrator to output -2V DC, and send the
following command to the Model 2001:
:CAL:PROT:LLEV:STEP 10
29. Set the calibrator output to 0V DC, and then send the
following command:
:CAL:PROT:LLEV:STEP 11
30. Connect the calibrator to the AMPS and INPUT LO ter-
minals, as shown in Figure 2-4.
31. Program the calibrator to output 20mA AC at a frequen-
cy of 1kHz. Send the following command to the Model
2001:
:CAL:PROT:LLEV:STEP 12
32. Set the calibrator output to +200mA DC. Send the fol-
lowing command to the Model 2001:
:CAL:PROT:LLEV:STEP 13
33. Program the calibrator to output +2A DC, then send the
following command to the Model 2001:
:CAL:PROT:LLEV:STEP 14
34. Connect the multifunction synthesizer to the Model
2001, as shown in Figure 2-5.
35. Set the synthesizer operating modes as follows:
FCTN: sine
FREQ: 1Hz
AMPTD: 2Vrms
MODE: CONT
36. Send the following command to the Model 2001:
:CAL:PROT:LLEV:STEP 15
37. Calculate new calibration constants by sending the fol-
lowing command to the Model 2001:
:CAL:PROT:LLEV:CALC
38. To check for calibration errors, send the following que-
ry:
:SYST:ERR?
If no errors are reported, calibration was successfully
completed.
