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
first calibration point.
CAL:LEV P1
16.
Press Shift Cal and scroll to CAL DATA. Wait for the DMM reading
to stabilize. Then read the DMM and compute the first current value
(DMM reading
÷
shunt resistance). Press Enter Number and enter
the first current value.
CAL:DATA 0.00
17.
Press Shift Cal, scroll to CAL LEV, use Ì to scroll to P2 (the
second calibration point), and press Enter.
CAL:LEV P2
18.
Press Shift Cal and scroll to CAL DATA. Wait for the DMM reading
to stabilize. Then read the DMM and compute the second current
value (DMM reading
÷
shunt resistance). Press Enter Number and
enter the second current value.
CAL:DATA 0.00
Low-Range Current Measurement Calibration
Action Display
19.
Press Shift Cal, scroll to CAL CURR MEAS LOW, and press
Enter.
CAL:CURR:MEAS:LOW
20. Connect the appropriate calibration load resistor as shown in
figure B-1B. Connect the DMM (in current mode) in series with
the load.
21.
Press Shift Cal, scroll to CAL LEV, and press Enter to select the
first calibration point.
CAL:LEV P1
22.
Press Shift Cal and scroll to CAL DATA. Wait for the DMM
reading to stabilize. Then press Enter Number and enter the
current reading displayed on the DMM.
CAL:DATA 0.00
AC Current Measurement Calibration (Agilent 66312A only)
Action Display
23. Disconnect all loads from the dc source.
24.
Press Shift Cal, scroll to CAL CURR MEAS AC, and press
Enter.
CAL:CURR:MEAS AC
25. Wait for the dc source to compute the ac current calibration
constant. The display returns to Meter mode when the calculation
is complete.
