Note:
• If the measured capacitance is shorted or the
capacitance exceeds the maximum range of the
meter, the display will show “OL”. It takes a
longer time to correctly measure capacitances
over 600uF.
• To ensure measurement accuracy, discharge all
residual charge from the capacitor under test
before connecting the capacitor to the meter.
This is particulary important for capactors with
high voltages to prevent damage to the meter or
to prevent personal injury.
• After completing measurement operations,
disconnect the test leads from the EUT.

8. Non-contact AC Voltage Sensing NCV (See
Figure 10)
In order to sense whether there is AC voltage or
an electromagnetic field present, place the front
-end of the clamp meter near the conductor to be
tested (distance <10mm). When the electric field
voltage is ≥100VAC, the display will indicate up
to four levels, “-”, “--”, “---”, “----”, based on the
sensed voltage.
The buzzer will beep continuosly and the NCV
LED will flash red.
