4. Test LV current
High voltage, very dangerous
!
Only
personnel
after
training
can
conduct
operation on it. The operator should bear
safety regulations in mind; otherwise there
can be the danger of electric shock resulting
in personal injury or casualty.
Testing the LV current by the HV detector
available
Testing the 4 circuit currents or leakers by
the HV detector available
It is prohibited to insert LV current clamp for
an accurate measurement.
It is prohibited to use low voltage current
clamps to detect high voltage wire above
600V or 10A; otherwise there can be the
danger of electric shock resulting in
personal injury or casualty.
1)
Connect three LV current clamps to the corresponding principal
machines, power on the machine into the test mode.
2)
Vise the measured wires with the LV current clamp (Note: the
clip should be fully closed), observe the readings of the secondary
current, if the machine displays
the symbol “OL A” while detecting
the secondary current, it is indicated that the measured secondary
current overflows the preset maximum of the LV clamp in the tester,
it is recommended to use the HV detector for its measurements.
The tester is capable of detecting three-channel or four-channel
current /leaker, please operate based on actual requirements.
