5. Push OPER on the 552xA to set the operate mode, if necessary, and wait for the calibrator
to stabilize.
6. Record the voltage, current, and power indication on the DUT in the test record.
7. Set the 552xA calibrator to output the next power test point (see Ta b l e 14 ).
8. Repeat steps 5 through 7 for all DC test points.
Note
Do not move on to AC current test points yet.
9. Set the 552xA calibrator into standby mode.
10. Set the 552xA calibrator to output the first AC power test point (see Ta b l e 1 4 ).
Note
For AC test points, it may be necessary to have the 552xA LCOMP feature on. The test
point table shows when to use LCOMP (see Ta b l e 1 4 ).
11. Push
on the DUT to switch to AC measurement mode.
12. Momentarily push
on the DUT to enter Continuous AC measurement mode.
13. Repeat steps 5 through 7 for all AC power test points.
14. Set the 552xA calibrator to standby mode.
When the calibration is complete, set all equipment to standby and disconnect all test leads.
