Charge calibration
Figure 2-28: Connecting the calibrator
11.Connect the calibrator CAL 542 in parallel to the device under test (DUT).
12.Keep the cable connections between CAL 542 and the DUT as short as possible.
13.After connecting and adjusting CAL 542, place CAL 542 inside of the high-voltage area, if available.
For the actual calibration, the high-voltage terminals have to be temporarily ungrounded.
WARNING
Death or severe injury caused by high voltage or current possible
► Always observe the five safety rules (see 1.2.2 "Safety rules" on page 6) before
entering the high-voltage area.
► Switch off the high voltage and ground the test setup before connection or
disconnection of CAL 542.
► Keep the high voltage switched off during the whole charge calibration process.
► During the actual calibration of the PD measurement, the high voltage has to be
temporarily ungrounded. Ensure that all safety rules are met at any time.
