Introduction
The CLM100 Cable Length Meter is ideal for measuring cable length on
the spool or in existing conduits. Includes test leads, copper calibration
bar, an abrasive pad for removing oxidation and carrying case.
Features include
• 3 digit display with enunciators
• Measures in FEET (ft) or METERS (m)
• Measures COPPER (CU) or ALUMINUM (AL) wire
• Resistance range for milliohm measurements
• Automatic temperature compensation
• User calibration mode. Calibration standard included
• Auto power off
WARNING!
Make sure wire under test is not energized. Never apply voltage
to inputs.
NOTE:
Temperature affects accuracy of readings. Please see accuracy
specifications. For best results, allow the CLM100 to attain the same
ambient temperature as the wire under test. The length of time this will
take depends on the ambient temperature. Typically it will take 10 to 15
minutes for the CLM100 to attain equal ambient temperature.
Safety Tips
Before using this meter, read all safety information carefully. In
this manual the word
"WARNING"
is used to indicate conditions
or actions that may pose physical hazards to the user. The word
"CAUTION"
is used to indicate conditions or actions that may
damage this instrument.

Operating Instructions
Calibration Procedures
1. Turn the CLM100 on by depressing the green on/off button
2. Insert the black test leads into one pair of input jacks and the
red test leads into the other pair of input jacks. (Ignore the gray
marking on the banana plug.) This is very important to ensure
that the meter works correctly. If black and red test leads are
mixed the unit will give a false reading. (Fig 1)
3. Connect the Kelvin clips to the calibration standard. Make sure
the clips are as close together as possible. (Fig 2)
NOTE:
Make sure the calibration standard is clean. The Kelvin
clips must be connected across the diameter of the standard.
Use the abrasive pad to clean the calibration standard.
NOTE:
Make sure clips are as close together as possible. Use the
tips of the Kelvin clips when performing measurements on small
diameter wire.
4. Press and hold the
“CAL”
button until all segments in the display
illuminate. This completes the calibration procedure and will
ensure all measurements are as accurate as possible.
5. Disconnect the leads from the standard.
Measuring Length of Wire
1. Turn the CLM100 on and perform the calibration procedure.
2. Allow the CLM100 to attain the same temperature as the
wire under test.
NOTE:
Temperature affects accuracy of readings. Please see
accuracy specifications. For best results, allow the CLM100 to
attain the same ambient temperature as the wire under test.
WARNING!
Make sure wire under test is not energized. Never apply voltage
to inputs.
