Enter the actual output value in scientific notation format. For example, if the calibrator’s display
shows 0.9999615 MΩ, enter this value as:
CAL:PROT:DC:STEP 2,0.9999615E6
11. Wait until the following message is displayed on the 2100:
Cali OK
12. Set the 5700A output mode to
STANDBY
.
13.
Set the 5700A to 0Ω, 2 WIRE COMP OFF, EX SNS button on, EX GRD button off, and output to
STANDBY
mode.
14. Using shielded, low-thermal EMF cables connect Fluke 5700A output HI, output LO, sense HI,
sense LO to the 2100 input HI, input LO, sense HI, and sense LO terminals. Allow connections to
stabilize for a minimum of five minutes before proceeding.
15. Set the 2100 to the four-
wire, 1 MΩ resistance function by sending the fo
llowing SCPI command:
CONF:FRES 1E6
16. Set the measurement rate to 10 PLC by sending the following SCPI command:
FRES:NPLC 10
17. Set the average function to 100 counts by sending the following SCPI command:
AVERAGE:COUNT 100
18. Set the 5700A output mode to
OPERATE
.
19. Adjust the input offset by sending the following SCPI command:
CAL:PROT:DC:STEP 1,1E6
20. Wait until the following message is displayed on the 2100 display:
Cali OK
21.
Set the 5700A output to 1 MΩ.
22. Adjust the full-scale measurement by sending the following SCPI command:
CAL:PROT:DC:STEP 2,<ACTUAL CALIBRATOR OUTPUT>
23. Wait until the following message is displayed on the 2100 display:
Cali OK
24. Set the 5700A output mode to
STANDBY
.
25. Set the 2100 to the four-
wire, 100 kΩ resistance function by sending the following SCPI
command:
CONF:FRES 1E5
26. Set the measurement rate to 10 PLC by sending the following SCPI command:
FRES:NPLC 10
27. Set the average function to 25 counts by sending the following SCPI command:
AVERAGE:COUNT 25
28.
Set the 5700A to 0Ω and output mode to
OPERATE
.
29. Adjust the input offset by sending the following SCPI command:
CAL:PROT:DC:STEP 1,1E5
