６−１ Current Measurement
WARNING
●
Do not make measurement on a circuit above 750V AC. This may
cause shock hazard or damage to the instrument or equipment under
test.
●
Transformer jaw tips are designed not to short the circuit under
test. If equipment under test has exposed conductive parts,
however, extra precaution should be taken to minimize the
possibility of shorting.
●
Do not make measurement with the battery compartment cover
removed from the instrument.
●
Do not make current measurement with the test leads connected to the
V/
Ω
and COMMON terminals.
●
When measuring current is not less than 1000A, make sure to stop
measurement within the maximum measuring time shown below.
Otherwise, transformer jaws may heat to cause a fire or
deformation of molded parts, which will degrade insulation.

６−１−１ AC Current Measurement (Normal Mode)
①
Set the function selector switch to the "
〜
400A" or "
〜
2000A"
position and make sure that the current under test does not exceed
the upper limit of the measuring range you are selecting.
②
Press the trigger to open the transformer jaws and clamp them onto
the conductor under test.
