NOTE
● During current measurement, keep the transformer jaws fully
closed. Otherwise, accurate measurement cannot be made. The
maximum measurable conductor size is approx. 55mm in diameter.
● When the current flows from the upside (the display side) to the
underside of the instrument, the reading is indicated positive.
● The Zero Adjust/Reset button may not completely zero adjust the
output voltage from the OUTPUT terminal. In this case, make zero
adjustment on the recording device.
● Turing the function selector switch to a position other than DCA
cancels the zero adjustment.
６－２ AC Current Measurement
 DANGER
● Never use the instrument on a circuit above 750VAC. This may
cause electrical shock hazard and damage to the instrument or
the circuit under test.
● Do not make measurement with the test leads plugged into the
instrument.
● Do not make measurement with the battery compartment cover
removed.
● Keep your fingers and hands behind the barrier during
measurement.
