OPERATING INSTRUCTIONS
AC/DC CURRENT (LESS THAN 600 A)
AC current is measured by pressing the clamp trigger
10
to open
the clamp
3
and placing it around a wire carrying a current. When
measuring, care should be taken to ensure that the clamp is
3
completely closed, with the trigger
10
fully released, and that the
wire passes perpendicularly through the centre of the clamp
3
in
line with the arrow markings
11
.
To measure current:
1. Rotate the Function selector switch
2
to the AC/DC current
A
setting.
NOTE:
The meter defaults to AC measurement. Press the 'SEL'
button
9
to toggle between AC and DC modes. The AC or DC
icon on the LCD indicates which mode is selected.
2. Place the clamp
3
around the wire. When measuring DC current,
align the polarity markings
15
on the clamp with the polarity of
the wire to avoid negative readings. The current measurement will
be shown in the display. The meter will auto-range to display the
measurement in the most appropriate range.
Disconnect test leads when measuring with the clamp.
NOTE:
If non-zero values are displayed prior to measuring in DC
current mode, an offset correction is required. With the meter in DC
current mode, press and hold the 'SEL' button
9
to activate the DC
current ZERO function. Subsequent DC current measurements will
automatically subtract the offset correction for improved accuracy.
