OPERATING INSTRUCTIONS
AC CURRENT (LESS THAN 400A)
AC Current is measured by pressing the clamp trigger
10
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
10
fully released, and that the wire
passes perpendicularly through the center of the clamp in line with
the arrow markings
11
.
To measure current:
1. Rotate the Function Selector switch
2
to the 200/400 A setting.
2. Place clamp around wire. The current measurement will be shown
in the display.
NOTE: If the measurement is less than 20A, rotate the Function
Selector switch

to the 2/20 A setting for improved resolution.
Disconnect test leads when measuring with the clamp.
