Measurement Operation
Note:
Remove plugs from
ends of Test Leads (included)
before connecting to Meter.
Note:
Test Lead probes have removable
covers for overvoltage protection. With
covers in place, Test Leads are rated for
use with CAT IV circuits. Exposed probes
are rated for use with CAT II circuits.
AC Current Measurement
Measure AC conductors carrying
up to 400 amperes.
WARNING!
To prevent electric
shock, test conductor voltages
with care.
Only use one hand when
securing clamp around conductor.
WARNING!
Remove Test Leads before
taking measurements with Current Clamp.
Note:
Amperage is always tested
in series with circuit under test.
Note:
To measure 2- and 3-wire power
cords, use an AC Line Splitter (not included)
and follow its instructions.
1. Turn Rotary Switch to
4A~
,
40A~
or
400A~
position. Start with highest
range if amperage is unknown.
2. Using one hand, press Trigger to open
Clamp Jaws. Position Clamp Jaws
around conductor to be tested.
3. Center conductor between arrows
in Clamp Jaws, as shown.
4. Read measurement. Switch to
lower ranges, as necessary, to
get most accurate reading.
5. To compare difference between
two readings, press
REL
button
to store current reading. Take
second measurement, reading
will be difference between
first and second reading.
6. When testing is complete, turn
Rotary Switch to
OFF,
and store Meter.
