Pro's Kit MT-3202 - Non-Contact Voltage Detection (NCV)

8
Note:
 Clamp two lines of the measured circuit or more at the same time will not obtain correct
measurement results.
 To obtain accurate readings, try to enable the measured cable in the middle position of
the current clamp.
4.6 Non-contact Voltage Detection (NCV)
1） Turn the rotary switch to the NCV position,
2） Put the clamp NCV sensor square close to the measured cable,
the meter could detect if the measured cable is >90V AC voltage
or not. When the meter detects AC voltage, the meter buzzer
alarms and the NCV LED flashes.
Note:
 Even there is no alarm indication, the voltage might still exist. Do not judge if there exist
voltage or not in the cable relying on non-contact voltage detector. The detection
operation might be affected by various factors such as the socket design and insulation
thickness types are different and so on.
 In NCV detection mode, the meter will not measure the voltage, resistance and current
at the same time.
4.7 Measurement of AC voltage and DC voltage
The meter provides DC voltage measuring ranges as follows: 400mV, 4V, 40V, 400V and
600V. AC voltage measuring ranges: 4V, 40V, 400V and 600V.
Measurement of AC voltage or DC voltage
1） Turn the rotary switch to the position “ V” and press “FUNC” to choose DCV or ACV.
2） Connect the test lead in black and test lead in red to COM input socket and V/Ω input
socket respectively.
3） Use another two ends of the test lead to measure the voltage of the circuit to be
measured. (In parallel connection with the circuit to be measured.)
4） Read the measured voltage value on LCD screen. When DC voltage measurement is
attempted, the display unit will show the voltage polarity of the circuit connected to the
lead-shaped meter in red.
Note:
 Within the measuring range of DC or AC voltage, even if there is no input or no
connection to the test lead, the meter will display some information. In this situation,
press short circuit “V” and “COM” terminal to reset the meter to zero.
 The value of the AC voltage measured with this meter is True RMS (root mean square).
These measurements are accurate for sine wave and other waves (without DC offset),
square wave, triangular wave and step wave.
