User Manual

The tester switch “OFF” completely when the rotary switch is in
the “OFF” position.
The tester has a “Hold the last reading before stopping the test”.
The tester is fuse protected and has a crowbar between C
1
and
C
2
. This crowbar is activated by voltage. If the voltage is too
high, that crowbar will blow the fuse automatically to interrupt the
circuit.
The voltage between P
1
and P
2
is also protected for over
voltage, but does not have a fuse.
The tester has a temperature shut down. The temperature
sensing is done on a current regulation transistor. Should this
over-temperature LED lit, allow the instrument to cool down for a
while before proceeding further.
