2. Measurement
2.2.1 AC Current Measurement (Normal Mode)
2.1 Preparation for Measurement
(1) Set the Function Selector switch to the "
400A" or "
2000A" position.
"AC" should be shown on the upper left corner of the display.
CAUTION
(2) Press the open/close lever 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.
● The jaw section is a delicate, precision sensor. Do not subject the jaw to
unreasonably strong shock, vibration, or force when using it.
● If dust gets into the tops of the jaws, remove it immediately. Do not close
the jaws when dust is trapped in its joints as the sensor may break.
● Please check that the function and mode are set to the desired setting
before measurement.
NOTE
● During current measurement, keep the transformer jaws fully closed. Otherwise, accurate measurement cannot be made. The maximum measurable conductor size is approx. 54.5mm in diameter.
● The transformer jaws may buzz when measuring large current. This has
no effect on the instrument’s performance or safety.
2.2 Current Measurement
WARNING
● Do not make measurement on a circuit above 750VDC. This may cause
shock hazard or damage to the instrument or equipment under test.
● Do not make current measurement with the test leads connected to the Hi
and Lo 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.
