OPERATING INSTRUCTIONS
TESTING IN CAT III / CAT IV MEASUREMENT LOCATIONS
Ensure the test lead shield is pressed firmly in place. Failure to use
the CATIII / CATIV shield increases arc-flash risk.
TESTING IN CAT II MEASUREMENT LOCATIONS
CAT III / CAT IV shields may be removed for CAT II locations. This
will allow testing on recessed conductors such as standard wall
outlets. Take care not to lose the shields.
AC CURRENT (LESS THAN 600A)
AC Current is measured by pressing the
clamp trigger
13
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
13
fully released, and
that the wire passes perpendicularly through
the center of the clamp
3
in line with the
arrow markings
14
.
To measure current:
1. Rotate the Function Selector switch
2
to the AC current A setting.
2. Place clamp
3
around wire. 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.
