６－１ DC Current Measurement
 DANGER
● Do not make measurement on a circuit above 1000VDC.
This may cause shock hazard or damage to the instrument or
equipment under test.
● 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 COM terminals.
● Keep your fingers and hands behind the barrier during
measurement.
① Set the function selector switch to the "

Ａ" position. “DC"
should be shown on the upper left corner of the display.
② With the transformer jaws closed and without clamping them onto
the conductor, press the Zero Adjust/Reset button for about one
second to zero adjust the display. (Zero adjust feature is for 400A
range only.) When zero adjustment is completed, "AUTO" appears
on the display.
③ Press the trigger to open the transformer jaws and clamp them onto
the conductor under test, then take the reading on the display. The
most accurate reading will be obtained by keeping the conductor at
the center of the transformer jaws.
