６．Measurement

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.

①Set the function selector switch to the " A" position. “DC" should

be shown on the upper left corner of the display.

②With 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.

③Press 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.
