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.
3.
Strip the insulation back on each end of the wire being tested.
NOTE:
Make sure both ends of the wire under test are clean and the conductor is fully exposed. The insulation
must be stripped away so the Kelvin clips can be connected across the diameter of the wire. Use the abrasive pad
to clean the wire ends.
4.
Using the selector on the CLM100, turn to the size of wire under test.
5.
Press the
“COPPER”
button if copper wire is being tested.
The
“CU”
enunciator will illuminate in the top left corner of the display.
6.
Press the
“ALUM”
button if aluminum wire is being tested.
The
“AL”
enunciator will illuminate in the top left corner of the display.
7.
Press the
“FT”
button if you require readings to be in feet.
The
“ft”
enunciator will illuminate in the display.
8.
Press the
“M”
button if you require readings to be in meters.
The
“m”
enunciator will illuminate in the display.
9.
Connect a Kelvin clip to one end of the wire and the other
Kelvin clip to the other end of the wire.
10. Read the length of wire directly from the display.
Please note the
“k”
enunciator illuminates if measurements are at or above 1000 feet/meters.
11. Disconnect the test leads from the unit when not in use.
Low Battery Indication
The
“BAT”
enunciator will illuminate in the lower left side of the display to indicate battery voltage is low.
The battery should be changed immediately to ensure proper function and accuracy. Only alkaline 9 Volt
batteries should be used.
Measuring Resistance
1.
If the resistance to be measured is wire, follow steps 1 through 3 under “Measuring Length of Wire.”
Then follow steps 2 and 3 below. If a discrete resistor is being measured, turn the cable length meter
on and perform the calibration procedure.
2.
Using the selector on the CLM100, turn to “R” on the dial.
3.
Read the resistance of the wire directly from the display.
