26.
Press Shift Calibration, scroll to the CAL LEV P1 command, use ° to
scroll to the P2 parameter, and press Enter. This selects the second
calibration point.
CAL:LEV P2
27.
Press Shift Calibration, scroll to CAL DATA 0.00, and use the Entry
keypad to enter the product of the transformer ratio times the ac voltage
value displayed on the DVM.
CAL:DATA 0.00
28.
Press Shift Calibration, scroll to the CAL LEV P1 command, use ° to
scroll to the P3 parameter, and press Enter.
CAL:LEV P3
29.
Press Shift Calibration, scroll to CAL DATA 0.00, and use the Entry
keypad to enter the product of the transformer ratio times the ac voltage
value displayed on the DVM.
CAL:DATA 0.00
30.
Press Shift Calibration, scroll to the CAL LEV P1 command, use ° to
scroll to the P4 parameter, and press Enter.
CAL:LEV P4
31.
Press Shift Calibration, scroll to CAL DATA 0.00, and use the Entry
keypad to enter the product of the transformer ratio times the ac voltage
value displayed on the DVM.
CAL:DATA 0.00
The ac source is now holding the new ac rms voltage calibration constants in RAM.
Calibrating the OVP Trip Point
Action Display
32.
Press Shift Calibration, scroll to CAL VOLT PROT, and press Enter.
CAL:VOLT:PROT
33. Wait for the ac source to compute the OVP calibration constant. The
display returns to Meter mode when the OVP calculation is complete.
The ac source is now holding the new OVP calibration constants in RAM.
Calibrating and Entering rms Current Values
Action Display
34. Connect the DVM (ac rms mode), current shunt, and load resistor as shown
in figure B-1 with S1 closed.
35.
Press Shift Calibration, scroll to the CAL CURR AC command, and
press Enter.
CAL:CURR:AC
36.
Press Shift Calibration, scroll to the CAL LEV P1 command, and press
Enter.
CAL:LEV P1
37.
Press Shift Calibration, scroll to the CAL DATA 0.00 command.
Calculate the rms current value (DVM ac rms voltage/shunt resistance), and
use the Entry keypad to enter the rms current.
CAL:DATA 0.00
38.
Press Shift Calibration, scroll to the CAL LEV P1 command, use ° to
scroll to the P2 parameter, and press Enter.
CAL:LEV P2
39.
Press Shift Calibration, scroll to the CAL DATA 0.00 command.
Calculate the rms current value (DVM ac rms voltage/shunt resistance), and
use the Entry keypad to enter the rms current.
CAL:DATA 0.00
