5-3
GENERAL TEST PROCEDURE
1. Make sure that Main Power Circuit Breaker on the Control Panel is in the Off position.
2. Make sure that all electrical connections have been properly and securely made and that the test
specimen is properly connected to the High Voltage Transformer (refer to Initial Set-up Procedures). Make
sure the Guard / Ground / Return Jumper Clip is set properly for test being performed. Make sure all
personnel are clear of danger and test area is clearly marked.
3. Connect Input Cable to Controls and to Power Source. Switch the Main Power Circuit Breaker on the
Control Panel to the On position.
4. Set Measurement Divider switch to the position that matches the High Voltage output being used.
5. Set Overload Trip dial to desired trip-out level.
(
NOTE
: In setting this device, it is important to take into account the capacitive current that the sample
under test will require. Set the dial to a high enough value to preclude false failure indications. If this
value is not known, it is recommended that the dial be left in a higher setting.)
6. Press the HV On switch.
(
NOTE:
The following conditions must be met before High Voltage will engage: Security Circuit Loop
must be closed, Emergency Off Switch must be closed (mushroom button up), Overload Reset Lamp must
be off, Voltage Control at Zero Start, Transformer Power Circuit Breaker on, and Ready lamp illuminated.)
7. Raise the manual Voltage Control knob on the Control Panel until desired test voltage level is
reached. Keep voltage at desired level for required duration. Record data if desired.
8. After completion of the test, manually return the Output Voltage to zero or its lowest level via the Voltage
Control knob.
9. Press HV Off momentary switch.
10. If during the test a failure should occur or if the Overcurrent Trip setting is exceeded, the High Voltage will
automatically shut off. In order to regain High Voltage, the Reset pushbutton must be pressed and
Voltage Control knob returned to Zero.
