Operational Hints
•
Never apply voltage to the inputs.
•
Temperature affects readings. Allow the CLM
33
to attain the
ambient temperature of the wire under test.
•
The sample length of user wires for the User Select Mode must be
5m in METER or 20ft in FEET mode.
•
The Listing label on the bottom case of the meter enables users to
make a short memo of each user wire for the User Select Mode.
•
Use a 9 volt alkaline battery only.
•
If the meter is on and inactivate for approximately 15 minutes, the
meter will automatically enter into Sleep mode and display “ ”.
Reactivate the meter by turning the selector to any position or
pressing any button.
•
Use the test leads that come with the meter only. Other leads will
not work.
•
Ensure that the test leads are clean and in good working order.
•
Use an abrasive pad similar to the one provided to ensure the
wire under test is clean and free of oxidation.
•
Ensure that the alligator clips are connected across the diameter
of the wire under test.
•
When measuring wire for insertion into conduit, add extra wire to
compensation for the accuracy of the meter. For example, 104m
of wire needed to run inside a piece of conduit that is 100m long.
(This would allow 2m on each end to attach the wire.) At
104m and
21°C, the cable length meter has an accuracy of ±1m.
In this case,
it would be safer to measure out 105m of wire.
This would ensure
that enough wire is available for the application.
