OPERATING INSTRUCTIONS
AC/DC CURRENT (LESS THAN 600A)
AC Current is measured by pressing the clamp trigger
10
to open
the clamp
3
and placing it around a current-carrying wire. When
measuring, care should be taken to ensure that the clamp
3
is
completely closed with trigger
10
fully released, and that the wire
passes perpendicularly through the center of the clamp
3
in line
with the arrow markings
11
.
NOTE: Current measurement can be made by clamping around
single conductors, but not cables containing both live and neutral
wires. In this case a line splitter is required, Klein Cat. No. 69409 is
recommended.
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 clamp
3
around 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 meter in DC
current mode, press and hold the "SEL" button
9
to activate the
DC current ZERO function. Subsequent DC current measurements
automatically subtract the offset correction for improved accuracy.
