Operating Instructions
Warning: Electric shock hazard: Do not connect the unit to live
voltage. Contact with live circuits could result in severe injury
or death.
Power ON/OFF
Rotate the function dial to any position to power on the meter. If the meter
does not turn on, check the batteries. For details on battery replacement,
refer to section ''Battery replacement'' for details.
Calibration Procedure
Every time the meter is turned ON, it must be calibrated before use.
1. Turn the function dial from the OFF position to the Ω position.
2. Connect the red Kelvin clip to the meter's red terminals.
3. Connect the black Kelvin clip to the meter’s black terminals.
Important: Ensure that both the calibration bar and the jaws of the
Kelvin clips are clean before proceeding.
I
4. Connect the two alligator clips to the supplied copper rod.
5. Adjust the clips so they are as close together as possible along
the rod.

8. Press the MEM button. If the display briey indicates “dOnE” and
then returns to resistance measurement mode, the calibration
has succeeded.
Note: If the display indicates "FAIL" after pressing the MEM Button,
the calibration has failed. Check whether the connections and contacts
are correct and secure.
9. If you press the CAL button again, the meter will exit calibration
mode and return to resistance measurement mode.

Measuring the Length of a Cable
Warning: Electric shock hazard: Do not connect the unit to live
voltage. Contact with live circuits could result in severe injury
or death.
1. Turn the function dial from the OFF position to the Ω position.
2. Follow the steps outlined in the "Calibration Procedure" to ensure
accurate measurements.
Note: Temperature affects the accuracy of the readings. For best
results, allow the meter and the cable to reach the same ambient
temperature. Typically, this takes about 30 minutes.
3. Strip the insulation from both ends of the cable. Ensure the exposed
conductor is clean and fully visible. If necessary, use abrasive paper
to remove any oxide layer from the exposed ends.
Note: Both ends must be clean for accurate measurement.
4. Adjust the function dial to the appropriate cable gauge position
based on the cable being measured.
Example: For a cable gauge of 1 mm², set the rotary switch to
the “1” position.
5. If the cable is copper, press the Cu/AI button until "Cu" appears on
the display. If the cable is aluminum, press the Cu/AI button until "AI"
appears on the display.
6. Press the FT/M button to choose the unit of measurement (feet
or meters).
7. Attach one alligator clip to one end of the cable and the other
alligator clip to the opposite end of the cable.
8. The display will indicate the measured length of the cable in the
selected unit (feet or meters) and the ambient temperature.

Note: If the temperature falls below 23°F (-5°C), the display will
show "-OL" to indicate it is out of range. If the temperature exceeds
122°F (50°C), the display will show “OL” to indicate it is out of range.
Press and hold the Cu/AI button to toggle between Celsius (°C) and
Fahrenheit (°F) display modes.
9. Once the measurement is complete, disconnect the alligator clips
from the cable.
User-selected Programming Mode:
The User Selected Mode offers the following functionalities:
Resistance Parameter Storage: Users can save the resistance
parameters of a specic cable for length measurements of cables with the
same characteristics (i.e., same gauge and conductor material).
Accurate Length Measurement: It allows precise measurement of
standard gauge cables.
Versatility: In this mode, users can measure the length of various metal
cables, including copper and aluminum cables.

How to Save the Resistance of a Test Cable
Note: Before starting, prepare a sample cable with a length between
4 m and 100 m (or 13.1 ft to 320 ft in FEET mode). This sample will
be programmed into the meter so that it can correctly measure and
store the resistance of this specic cable type. Ensure the cable being
measured is not energized or live.
1. Turn the function dial from the OFF position to the Ω position.
2. Follow the steps outlined in the “Calibration Procedure” to calibrate
the meter.
Note: Temperature affects the accuracy of the readings. For best
results, allow the meter and the cable to reach the same ambient
temperature. Typically, this takes about 30 minutes.
3. Remove the insulation from both ends of the sample cable.
Note: Ensure the two conductors are clean and fully exposed. Use
a grinding pad if needed to clean the exposed cable ends for better
conductivity and easier clamping with the test rods.
4. Use the function dial to select a
User-Dened Mode from 1 to 8.
5. The selected User-Dened mode will be
displayed in the bottom right corner of the
screen. If the selected User-Dened mode
already contains a stored cable parameter,
the screen will display "OL" as shown below.

8. Use the Up/Down buttons to adjust the displayed value.
9. Adjust the display until it matches the actual length of the sample
cable to be measured.
10. Attach one alligator clip to each end of the sample cable, ensuring
secure connections at both ends.
11. Press the MEM button. If the display briey indicates “dOnE” and
then returns to measurement mode, the setting has succeeded.
Note: If the display indicates "FAIL" and "ERROR", the setting has
