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 CLM100B, 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. For example, when the “
k
” enunciator is on
and you are measuring in feet, a reading of 15k ft would indicate
a length of 15000 ft.
11. Disconnect the test leads from the unit when not in use.
User Select Mode
This mode allows you to save the resistance of a user wire (see NOTE
below) for additional measurements of unknown lengths of the same
gauge wire. in addition, it enables you to accurately measure the length
of standard gauge wires. In this mode, you can measure the length of
any metal wire, the resistance of which can be measured, as well as
Copper or Aluminum wires.
NOTE:
The sample length of user wires must be 20ft in FEET or 5m in
METER mode.
How to Save the Resistance of a User Wire
NOTE:
You will need a 20’ (or 5M in meter mode) sample length of the
wire you are programming into the meter. This will measure the resist-
ance of that wire and store a value to correctly measure longer lengths.
1. Turn the CLM100B on and perform the calibration procedure in
the “
R
” position.
2. Allow the CLM100B to attain the same temperature as the
user wire.
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 CLM100B, turn to a required memory
location in the User Select range. The meter has 6 internal
memory locations from 1 to 6, and the selected memory location
number will illuminate at the top left corner of the display. If the
selected memory location is occupied, the display shows
“
0000
”. If the selected memory location is empty, the display
shows “
no
”.
5. Press the ”
FT
” or ”
M
” button to select the measurement unit.
6. Press the Kelvin clip to one end of the 20’ section of the user wire
and the other Kelvin clip to the other end of the wire.
7. Press the ”
MEM
” button to enter the Memory function. The
“
MEM
” enunciator will illuminate in the top of the display.
8. Press ”
CAL
” button to store the resistance of the user wire.
9. If there is any stored resistance value in the selected memory
location, the meter will display “
SurE
”. In this case, press “
CAL
”
button again to store the new resistance value.
10. Press “
MEM
” button or turn the selector to any position in order
to exit Memory function.
Measuring Length of Wire in the User Select Mode
1. Turn the CLM100B on and perform the calibration procedure in
the “
R
” position.
2. Allow the CLM100B to attain the same temperature as the wire
under test.

4. Select the required memory location in the User Select Mode
using the selector and the Listing label on the bottom case.
5. Press the “
FT
” or “
M
” button to select the measurement unit.
6. Connect a Kelvin clip to one of the wire under test and the other
Kelvin clip to the other end of the wire.
7. Read the length of wire directly from the display.
8. Disconnect the test leads from the meter when not in use.
