Appendix 5 Supplying DC Bias
A8
• In order to avoid electric shock accident, be absolutely sure not to touch the test termi-
nals while the DC bias voltage is being supplied to them.
• If you disconnect the sample under test from the test terminals with the DC bias voltage
still being supplied, then the test sample is left charged, which is very dangerous. In
order to avoid electric shock
• accident, be absolutely sure to discharge the test sample.
• Do not short circuit between the clips of the test probes with the DC bias voltage still
being supplied. Doing so may damage the probes or cause a short circuit accident.
• When measuring the element whose DC resistance is not high enough, DC current will
flow to the main unit and the measurement will not be performed properly.
