CONTROLS AND CONNECTIONS
FRONT PANEL CONTROLS AND METERS
Power On:
When depressed and locked, this illuminated pushbutton switch (green lens) supplies
power to all unit components with the exception of the high voltage power supply.
Voltage Control:
Clockwise rotation of this control increases the unit’s output voltage. The unit’s output
range is 0-15,000 volts DC. This control must be returned to the “0” (full counter
clockwise position) before a test can be initiated if either the “Power” or “High Voltage”
switches have been previously disengaged, or if an overcurrent condition has been
encountered.
High Voltage:
When depressed and locked, this illuminated pushbutton switch (red lens) supplies power
to the unit’s high voltage power supply, if voltage control is set at “0”. If voltage control is
not set at zero, high voltage will not activate and buzzer will sound until voltage control is
returned to zero.
Currentmeter-Megohmmeter:
The currentmeter range is selected by the five position rotary switch. The switch setting
indicates the full scale current of the currentmeter and the megohmmeter multiplier. The
table below shows the full scale currentmeter range with each switch setting.
The megohm multiplier is selected by the same five position switch as the currentmeter
range. This allows direct megohm readings at 5 and 10 kV. In order to read megohms
directly, the kilovolt meter must be set to either 5 or 10 kV. The megohms are then read
from the right hand meter, megohms at 10 kV on the top scale and megohms at 5 kV on
the middle scale. The table below shows the megohm range for each switch setting and
kilovolt range.
