External Control
Monitoring Measurements
The current waveform and voltage waveform of the withstanding voltage test can be checked with the
signals output from the monitor terminals on the rear panel.
In the partial discharge test mode of TOS930
1PD, the current waveform and electric charge waveform can
be monitored.
Monitoring current waveforms
Current waveforms of withstanding voltage tests can be monitored using the signal output from the I
terminal on the rear panel. (Except for the partial discharge test mode of TOS9301PD)
Monitoring voltage waveforms
Voltage waveforms of withstanding voltage tests can be monitored using the signal output from the V
terminal on the rear panel.
TOS9300, TOS9301, TOS9302,
TOS9303, TOS9303LC
TOS9301PD
Monitor signal output is isolated from the chassis (earth). If you connect an oscilloscope or an
external device whose BNC shield is grounded for other than PD tests, be sure to set the
grounding mode (GND) on the test conditions to Guard.
This will not be an issue for PD tests (no GND setting).
