2.3 Method of Operation
2.3. 1 Connect the equipment as described in Section 2.1 .
2.3. 2 Remove the power switch operating key before connecting the equipment to the main
supply. This will ensure the equipment is in the OFF position as the key is only
removable in that position. The key is trapped in the ON position.
2.3. 3 Once the equipment is connected to the main supply the key operated switch can be
moved to the ON position. The following will now occur:
a. Power ON lamp will be lit
b. HV OFF lamp will be lit
c. The variable overload reset lamp will be lit
2.3. 4 Press the variable overload reset push-button thus arming the circuit. The indicator lamp
in the reset push-button will go out thus indicating that the circuit is armed.
2.3. 5 Select the desired voltage range on the kV meter and set the desired overload mA trip
level.
2.3. 6 Before commencing testing ensure that the regulator is in the fully anticlockwise position.
2.3. 7 Depress HV ON push-button and this will close the internal circuit breaker The HV OFF
lamp will extinguish and the HV ON lamp will be lit. The output voltage can now be
increased to the desired level as indicated on the kV meter.
2.3. 8 In the event of a test object failure the HV output will be automatically switched off by the
protection system.
2.3. 9 When the test is completed, turn the regulator control knob fully anti-clockwise and switch
off the HV output and then the main supply.
