AC/DC CURRENT (LESS THAN 400A)
AC Current is measured by
pressing the clamp trigger
to open the clamp and placing it
around a current-carrying wire.
When measuring, care should be
taken to ensure that the clamp
is completely closed with trigger
fully released, and that the
10
wire passes perpendicularly
through the center of the clamp
in line with the arrow markings
To measure current:
1. Rotate the Function Selector switch
to the 400A setting.
2. Place clamp around wire. The current
measurement will be shown in the display.
NOTE: The meter defaults to AC measurement. Press the SEL/NCV
button to toggle between AC and DC modes. The AC or DC icon on
the display indicates which mode is selected.
NOTE: If the measurement is less than 40A, rotate the Function
Selector switch
NOTE: If non-zero values are displayed prior to measuring in DC
current mode, a DC zero offset correction is required. With meter in
DC current mode, press the REL/ZERO button
current ZERO function. ZERO icon will be present on the display.
Subsequent DC current measurements automatically subtract the
offset correction for improved accuracy. Press REL/ZERO button
to return to normal measuring mode.
Disconnect test leads when measuring with the clamp.
