Current Programming and High-Range Measurement Calibration

Action

Display

13.Connect the appropriate current monitor as shown in figure B-1A. Connect the DMM (in dc mode) across the current shunt.

14.

Press Shift Cal, scroll to CAL CURR, and press Enter.

CAL:CURR

15.

Press Shift Cal, scroll to CAL LEV, and press Enter to select the

CAL:LEV P1

 

first calibration point.

 

16.

Press Shift Cal and scroll to CAL DATA. Wait for the DMM reading

CAL:DATA 0.00

 

to stabilize. Then read the DMM and compute the first current value

 

 

(DMM reading ÷ shunt resistance). Use the Entry keypad to enter the

 

 

first current value.

 

17.

Press Shift Cal, scroll to CAL LEV, use to scroll to P2 (the

CAL:LEV P2

 

second calibration point), and press Enter.

 

18.

Press Shift Cal and scroll to CAL DATA. Wait for the DMM reading

CAL:DATA 0.00

 

to stabilize. Then read the DMM and compute the second current

 

 

value (DMM reading ÷ shunt resistance). Use the Entry keypad to

 

 

enter the second current value.

 

Negative Current Programming Calibration

 

 

Action

Display

19.Connect a negative supply to the output in series with the appropriate load resistor as shown in figure B-1C. Set the DMM to operate in current mode. Set the negative supply to the full scale voltage rating of the UUT.

20. Press Shift Cal, scroll to CAL CURR NEG, and press Enter.

CAL:CURR:NEG

21.Wait for the dc source to compute the negative current calibration constant. The display returns to Meter mode when the calculation is complete.

Low-Range Current Measurement Calibration

Action

Display

22.Press Shift Cal, scroll to CAL CURR MEAS LOW, and press Enter. CAL:CURR:MEAS:LOW

23.Connect the UUT as shown in figure B-1B with the appropriate load resistor for your model. Set the DMM to operate in current mode.

24.

Press Shift Cal, scroll to CAL LEV, and press Enter to select the

CAL:LEV P1

 

first calibration point.

 

25.

Press Shift Cal and scroll to CAL DATA. Wait for the DMM reading

CAL:DATA 0.00

 

to stabilize. Then use the Entry keypad and enter the current reading

 

 

displayed on the DMM.
