TEST VOLTAGE
Control
This control is to adjust the test voltage. As you turn the control clockwise from the “0” position,
the test voltage increases. The “MAX” position is for the highest test voltage corresponding to
the voltage range value selected by the TEST VOLTAGE switch
5
.
For the AC/DC models (TOS5101 and TOS5051), the control is for both AC and DC test modes.
Model Selectable ranges and mode
TOS5101 0 to 10kV AC or more 0 to 5kV AC or more
0 to 10kV DC or more 0 to 5kV DC or more
TOS5051 0 to 5kV AC or more 0 to 2.5kV AC or more
0 to 5kV DC or more 0 to 2.5kV DC or more
TOS5050 0 to 5kV AC or more 0 to 2.5kV AC or more
Caution
• Be sure to keep the
TEST VOLTAGE
control
6
in the fully
counterclockwise position (“0” position) whenever no test is done.
• When the
TEST VOLTAGE
control
6
is set in the fully clockwise
position (“MAX” position) in the no load state, the output voltage in
the DC mode may be higher than the test voltage range value you
selected with the
TEST VOLTAGE
switch
5
. In the AC mode, the
output voltage may be higher still depending on change of the AC line
voltage. Although higher voltages may be available, be sure to
operate the Tester with voltages lower than the corresponding range
value.
7
HIGH VOLTAGE Terminal
This terminal is for the high line of the Tester output. The output voltage is delivered between
this terminal and the
LOW
terminal
8
. For the AC/DC models (TOS5101 and TOS5051), this
terminal serves in common for both AC and DC modes of test operation.
WARNING
• Never touch the
HIGH VOLTAGE
terminal
7
when in the
TEST-ON status (status that the DANGER lamp
9
lights or the
TEST
message
29
appears).
8
LOW
Terminal
This terminal is for the low line of the Tester output. This terminal is directly connected to the
Tester chassis.
