Note, HV ON/OFF Button will be grayed out until E-Stop is OFF, Interlock Circuit is
CLOSED, Power input is connected, and the Amplifier turns on.
1. Before starting the test, confirm Ungrounded-Specimen-Test (UST) or Grounded-
Specimen-Test (GST) Current Measurement Circuit option. If the test specimen’s
return is ungrounded, select UST, and refer to section 5.1.2. If the test specimen’s
return is grounded, select GST, and refer to section 5.1.1.
Example Operation Interface with High Voltage On
In the image above, the unit is in operation in Manual mode. The HV ON/OFF button is
red, indicating the presence of high voltage. The test circuit mode, target voltage, and
leakage current threshold are set and cannot be changed during operation. Meter
displays can be toggled between analog and digital during testing. Resistance is
