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 5m in
METER or 20ft in FEET mode.
Note:
You will need a 5M (or 20ft in feet mode) sample length of
the wire you are programming into the meter. This will measure
the resistance of that wire and store a value to correctly measure
longer lengths.
1. Turn the CLM
33
on and perform the calibration procedure in the
“R” position.
2. Allow the CLM
33
to attain the same temperature as the user wire.
WARNING: MAKE SURE USER WIRE IS NOT ENERGIZED.
NEVER APPLY VOLTAGE TO INPUTS.
3. Strip the insulation back on each end of the user wire.
NOTE: Make sure both ends of the user wire 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 CLM
33
, turn to a required memory location
in the User Select range. The meter has 8 internal memory locations
from 1 to 8, 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 “ ”.
If the selected memory location is empty, the display shows “ ”.
5. Press the “FT” or “M” button to select the measurement unit.
6. Connect a Kelvin clip to one end of the 5m section of the user
wire and the other Kelvin clip to the other end of the wire.
7. Press “MEM” button to enter the Memory function. The “ ”
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 “ ”. 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.
1. Turn the CLM
33
on and perform the calibration procedure in
the “R” position.
2. Allow the CLM
33
to attain the same temperature as the wire
under test.
WARNING: MAKE SURE USER WIRE 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. 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.
1. Disconnect the test leads from the meter.
2. Select the required memory location to be cleared in the User
Select range using the selector.
3. Press “MEM” button to enter the Memory function. The “ ”
enunciator will illuminate in the top of the display.
4. Press “CAL” button. Then, the meter will display “ ”.
5. Press “CAL” button again to clear the stored data.
6. Press “MEM” button or turn the selector to any position in order to
exit Clearing memory function.
