Alarm Function
Press the
button to enable the alarm function after the HI and LOW limits are set. The
symbol will be displayed in the LCD.
If the resistance measured falls within the range of HI and LO limits, a symbol of PASS is shown
in the LCD. If not, the buzzer will beep to indicate a fail.
If the reading is OL, the alarm function is temporarily disabled until a reading is obtained.

Cable Length Measurement
1. Prepare a 1 foot or a 1-meter-long sample from the cable to be measured.
2. Select the proper range of resistance, press the
START
button and measure the resistance of
the sample.
3. Press
the
Ω
/LENGTH
button for over 2 seconds. The meter will beep and the LCD will display
units of FT or m. The measured value is stored and used to determine cable length.
4. If needed, press the
FEET/METERS
button to change the units. If the units are changed, press
the
Ω
/LENGTH
button for over 2 seconds again.
5. Disconnect the sample cable and connect the Kelvin clips to the cable to be measured. The
