Note:
1) Clamping two or more leads of circuit to be tested simultaneously
will not give correct readings.
2) To get accurate reading, connect the lead to be tested at the center
of current clamp.
3) In the manual measuring range mode, when LCD only shows "OL",
which indicates over-range, choose higher measuring range.
4) In the manual measuring range mode, if you don't know the size of
value to be measured in advance, choose the highest measuring
range, then decrease gradually until the correct range is displayed..
4.18 NCV Measurement
1) Turn the meter to NCV Range.
2) The meter shows "NCV" sign, the main display of meter shows
- - - -; and the alternate display shows the current NCV detection
sensitivity "SE-n" (number of n is from 0 to 9). The bigger digit is,
the higher sensitivity will be. Press RANGE key to increase sensitivity,
MEM key to reduce sensitivity. Press HOLD key to save the setting
sensitivity.
Note:
1: Even there is no indication, voltage may exist still. Don't use
non-contact voltage detector to test whether there is voltage
in the wire. Detection operation could be affected by socket
design, insulation thickness, type and other factors.
2: When inputting voltage on the meter input terminal, due to the
existence of the induced voltage, voltage induction indicator also
may light.
3: Interference sources of external environment (such as flashlight,
motor, etc.) may trigger non-contact voltage detection by mistake.
