Operation
Electric shock hazard:
Do not connect the unit to live voltage.
Contact with live circuits could result
in severe injury or death.

Calibration Procedure

Each time the meter is turned ON, it should be calibrated
before use.
1. Refer to "Typical Measurements" for calibration setup
diagram.
2. Ensure the calibration bar and Kelvin clips jaws are
clean.
3. Move rotary switch from the OFF position to Ω.
4. Ensure that both leads for the red set of Kelvin clips
are plugged into the red terminals on the meter.
Ensure that both leads for the black set of Kelvin clips
are pluggged into the black terminals on the meter.
5. Place each Kelvin clip on the calibration bar. Move the
clips as close together as possible.
6. Press the CAL button. Dashes appear on the LCD.
Next "MEM" and "donE" appear on the LCD. Then
"RES" on the LCD indicates the meter is back in
resistance mode. If "FAIL" appears on the LCD and the
buzzer sounds, there was an issue with the calibration
process. Turn meter OFF and return to step 1 of this
procedure.
7. After successful completion of the calibration process,
the meter is ready for normal operation.

Operating Procedure

1. If the unit does not function as expected on a known
functioning configuration, replace the batteries.
If the unit still does not function as expected, call
Greenlee for technical assistance at 800-435-0786.
2. Refer to "Typical Measurements" for specific mea-
surement instructions.
3. The meter does not compensate for manufacturing
tolerances of various cable manufacturers.
4. Before making a measurement, ensure the following:
• Cable conductors have been cleaned with
abrasive material to remove oxide layer and other
contaminants.
• Kelvin clip jaws are clean.
• Both the cable and meter are at the same
temperature.
• Cable conductor material must be either aluminum
or copper.
5. To measure odd cable sizes:
• AWG (5, 7, 9, 11 AWG, etc.) (CLM-1000): When
measuring odd numbered cable sizes, set the rotary
switch to the next smaller size, and multiply the
reading by 1.261.
For example, to measure a 9 AWG length of cable,
set the rotary switch to 10 AWG. Then multiply the
reading by 1.261 to get the length.
• kcmil (CLM-1000): When measuring odd
numbered cable sizes, set the rotary switch to
1000 kcmil. Divide kcmil size of cable being mea-
sured by 1000, and then multiply this number by the
meter's length reading.
For example, 477 kcmil cable is being measured.
The multiplier becomes 477/1000 = 0.477. Take
the value shown with the rotary switch in the 1000
kcmil position and multiply it by 0.477 to get the
length.
• mm 2 (CLM-1000E): When measuring odd
numbered cable sizes, set the rotary switch to
2
500 mm . Divide mm
sured by 500, and then multiply this number by the
meter's length reading.
For example, 289 mm
The multiplier becomes 289/500 = 0.596. Take the
value shown with the rotary switch in the 500 mm
position and multiply it by 0.596 to get the length.

Programming Procedure

1. Calibrate meter according to "Calibration Procedure."
2. Obtain known length of cable between 30 ft and
320 ft (9 m and 97.5 m) long. Cable must be alumi-
num or copper.
3. Set rotary switch to desired location. Programmable
location appears on the LCD. If the location has
already been programmed, "OL" appears on the LCD.
If it has not, "no" appears.
Note: Data in a programmed location can be deleted.
With Kelvin clips removed from cable and rotary
switch turned to location to delete, press MEM button.
4. Press CAL button.
5. Enter the known length of cable in feet or meters.
Use qp arrows.
6. Select "Cu" or "Al".
7. Connect Kelvin clips to the conductor on each end of
the cable.
8. Press MEM button. "MEM" and dashes appear on the
LCD. After approximately 1 second, "donE" appears
on the LCD if programming was successful. If "FAIL"
appears, check connections and repeat procedure.
