Action
5.
Connect the DMM (in voltage mode) directly to the dc source. Do
not connect the load resistor or current shunt.
6.
Press Shift Cal, scroll to CAL VOLT, and press Enter.
7.
Press Shift Cal, scroll to CAL LEV, and press Enter to select the
first calibration point.
8.
Press Shift Cal, scroll to CAL DATA, press Enter Number, and
enter the voltage value displayed on the DMM.
9.
Press Shift Cal, scroll to CAL LEV, use
second calibration point), and press Enter.
10.
Press Shift Cal, scroll to CAL DATA, press Enter Number, and
enter the second voltage value displayed on the DMM.
Overvoltage Protection Calibration
Action
11.
Press Shift Cal, scroll to CAL VOLT PROT, and press Enter.
12.
Wait for the dc source to compute the OVP calibration constant. The
display returns to Meter mode when the calculation is complete.
Current Programming and High-Range Measurement Calibration
Action
13.
Connect the appropriate current monitor as shown in figure B-1A.
Connect the DMM (in voltage mode) across the current shunt.
14.
Press Shift Cal, scroll to CAL CURR, and press Enter.
15.
Press Shift Cal, scroll to CAL LEV, and press Enter to select the
first calibration point.
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 in amperes.
17.
Press Shift Cal, scroll to CAL LEV, use
second calibration point), and press Enter.
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 in amperes.
