NOTE:
The power will become automatically off approx. 10 minutes after the switch
operation due to auto power off function.
Measurement of line current cannot be done on Ior current mode.
Current measurement ranges of this instrument are auto but it can be changed to
manual in case that the range cannot be fixed due to input fluctuation.
Please refer to (5) Change of Current Range for the operation.
(2) Leakage Current Measurement
1)
Measurement at grounding line
Do the same method as for line current measurement.
2)
Measurement for other circuit except for grounding line
The operations are the same as for line current but clamp CT to 2 wires en bloc in
case of single phase and 3 wires en bloc in case of 3 phase.
(3) Voltage Measurement (500V Range)
1)
Press POWER switch once. All display lightens
and the range becomes Io current measurement.
2)
Press Voltage display switch once and the display
changes to voltage.
3)
Set Frequency switch according to the circuit
to be measured.
4)
Insert the test leads into the voltage input
terminals (Red & White).
5)
Connect the test lead clips to the circuit to
be measured.
6)
Read the displayed value.

WARNING
Do not apply the voltage more than 500V AC to the voltage input terminals
(~VINPUT). It may cause breakage

POSSIBLE ELECTRICAL SHOCK
●
Measuring test leads are consumable articles. Confirm there is no damage at
insulation coating of the wire before use. When having found unusual point,
stop the use and repair or replace to the new one.

POSSIBLE BURNING & WOUND
●
Connect the lead wires correctly & firmly.
It may cause spark by mis-connection.
