CONTROLS AND CONNECTIONS
FRONT PANEL CONTROLS AND METERS
Raise Voltage:
Clockwise rotation of this control increases the tester
’
s output voltage. The tester
’
s output
range is 0-6,000 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.
Power:
When depressed and locked, this illuminated pushbutton switch (green lens) supplies AC
power to all tester components with the exception of the high voltage power supply.
High Voltage:
When depressed and locked, this illuminated pushbutton switch (red lens) supplies AC
power to the tester
’
s high voltage power supply. In normal operation this switch will
illuminate when depressed if the
“
Raise Voltage
”
control has been set to
“
0
”
. Illumination
of this switch indicates that high voltage output is available.
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.
Currentmeter Ranges
Switch Setting Currentmeter Ranges
.5 microamps 0-.5 microamps
5 microamps 0-5 microamps
50 microamps 0-50 microamps
500 microamps 0-500 microamps
5000 microamps 0-5000 microamps
The megohm multiplier is selected by the same five position switch as the current-meter
range. This allows direct megohm readings at 2.5 and 5 kV. In order to read megohms
directly, the kilovolt meter must be set to either 2.5 or 5 kV. The megohms are then read
from the right hand meter, megohms at 5 kV on the top scale and megohms at 2.5 kV on
the middle scale. The table below shows the megohm range for each switch setting and
kilovolt range.
Megohmmeter Ranges
Switch Setting 2.5 kV 5 kV
x10K 5,000 - 500,000 megohms 10,000 - 1,000,000 megohms
x1K 500 - 50,000 megohms 1,000 - 100,000 megohms
x100 50 - 5,000 megohms 100 - 10,000 megohms
x10 5 - 500 megohms 10 - 1,000 megohms
x1 .5 - 50 megohms 1 - 100 megohms
