5.6 NCV (Non-Contact Voltage) Detection
WARNING:
Due to external interference source, this function may cause wrong voltage detection, the detection
result is for reference only.
Set the rotary switch to NCV position, contact the top part of meter with the circuit under test, the
indicating LED will flash and audible signal will sound.
NOTE:
● The detection result is for reference, do not determine the voltage by NCV detection ONLY.
● Detection may interfere by socket design, insulation thickness and other variable conditions.
● The external interference sources, such as flashlight, motor, etc, may cause the wrong detection.
5.7 LINE (Live Wire Recognition) Test
Set the rotary switch to LINE position, connect the black test lead to COM jack and red test lead to
VΩmA jack, hold the insulation part of black test lead and not put into circuit under measurement;
contact the red test lead to live wire, the buzzer of meter will be activated and red LED will be
flickered, when the red test lead connect the earth line, the buzzer does not sound and LED will not
flicker.
NOTE:
When the circuit is severely leaking (approx. Above 15V) and the red test lead contacts the ground
line, the meter bell will sound and the LED will flash.
