AC/DC CURRENT (LESS THAN 2000A)
AC Current is measured by pressing the
clamp trigger
and placing it around a current-carrying wire.
When measuring, care should be taken to
ensure that the clamp
closed with trigger
that the wire passes perpendicularly through
the center of the clamp

To measure current:
1. Rotate the Function Selector switch

2. The meter defaults to AC measurement. To
measure DC, press the "SEL/DC ZERO"
button to toggle between AC and DC
