• Never apply voltage to the inputs.
• Temperature affects readings. Allow the CLM100 to attain the ambient temperature of the wire under test.
• Use a 9 Volt alkaline battery only
• Use the test leads that came with the unit 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 insulation is stripped adequately from both ends of the wire under test. This will enable
measurements to be accurate.
• 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 compensate for the accuracy of the
meter. For example, 205 feet of wire is needed to run inside a piece of conduit that is 200 feet long. (This
would allow 2.5 feet on each end to attach the wire.) At 205 feet and 70˚F, the cable length meter has an
accuracy of ±7 feet. In this case it would be safer to measure out 212 feet of wire. This would ensure that
enough wire is available for the application.
