1.
Rotate the rotary switch to
.
2.
Connect the red test lead to the
terminal.
3.
Measure the object undergoing testing with a
test lead.
4.
If a voltage is detected, the indicator light on the
top of the display will flash, and the multimeter
will emit a “beep beep beep” sound. The sound
will change with the level of the detected voltage.
When a high voltage is measured, the screen
will display “---H”, and when a low voltage is
measured, the screen will display “---L”.
Live Wire Detection
To detect the presence of AC voltage, place the
top of the multimeter close to a voltage source.
When voltage is detected, the LED above the
display will glow, and the multimeter will beep.
Taking Measurements (cont.)
Non-Contact Voltage
Detection (NCV)
Warning:
• Always
test the NCV function on a known live
circuit before use.
• Do not
attempt to use the multimeter as an AC
Voltage Detector if the battery is weak or bad.
•
Even without indication, voltage may still be
present.
Do not
rely on NCV detection to check
a shielded wire. Detection could be impaired
by socket design, insulation thickness, or other
factors.
•
External interference such as static electricity
sources could mistakenly trigger NCV indication.
