voltage detector NT-320
User manual
Warning
Please read the instruction manual carefully before
use and strictly observe the safety rules and the
caution, attention and warnings listed in the
instruction manual.
Safety Instruction
Warning
To avoid possible electric shock or personal injury:
The protection provided by the stylus can be
compromised or rendered useless if you fail to
use it according to instructions.
Before using the voltage detector, please test
on a known live power supply to ensure that the
detector is in good working condition.
When using voltage detector, even if there is no
indication or no sound alarm, there may be a
voltage. Do not use the product if it is
damaged or does not work properly. If any
problem is suspected, please send it to repair
in time.
Do not apply more than the rated voltage
marked on the probe.
When testing voltages above 30 volts, be extra
careful, because such a voltage will pose a risk
of electric shock.
Comply with local and national safety
regulations and use appropriate protective
equipment as required by local or national
authorities.

Operation Description
Power on/ off
Press the power key and keep up for more than 1
second, the buzzer deeps and the screen lit up then
entered the open state.when the meter is turned
on,press the power key and keep up for more than
1 second, meter turn off.
Flashlight
When the meter powered on, press the
“power/lightbutton to turn on the flashlight; when
the flashlight is turned on, press the “power /light”
button again to turn it off.
The meter will be turned off automatically after 5
minutes when there is no induction signal and no
operation.
Broken point search/Inductive Mode
Measuring
Power-on default sensing mode measurement
status. When the probe of the test pen is placed
close to the AC voltage source, the buzzer sounds;
the frequency of the buzzer sounds has three levels,
which increases with the signal. At the same time,
the display screen will display " U" , and "HI"
when the signal is strong. With this function, you
can find the break point of the wire.
AC Voltage Detection
After starting up, press and hold the contact
measurement key to enter the AC voltage
measurement mode. When the probe of the test
pen contacts the conductor with AC voltage, the
display screen displays the corresponding AC
voltage. This function can detect the AC voltage and
distinguish the zero and live wires according to the
voltage.
Wire connected detection
After the machine is turned on, press the test pen
conduction/positive pole measurement button with
the right hand, hold one end of the uncharged wire
with the left hand, contact the other end of the wire
with the probe of the test pen, if the wire is
connected normally, the display will display the "- -
C" and buzzer sound, if the wire is open, the test
pen does not respond.
Voltage Positive detection
After starting up, press and hold the
connection/positive pole measurement key of the
test pen with the right hand and the negative pole
like of the battery with the left hand; use the
probe of the test pen to touch the positive polelike
of the battery. If it is correct, the display screen
will display " P" and the buzzer will sound. If
it is connected reversely, the test pen will not
respond.
In general, when the backlight is red, it indicates
that the object under test may be dangerous
and should be operated carefully.
Warning
1When using, please ensure that the human
body is insulated to the earth, please wear well-
insulated shoes; a certain part of the human
body contact with an electrified object, Large
areas of metal or the Earth, will affect the
accuracy of the measurement.
2This product can only be used to measure
the AC voltage(≤300V 50/60Hz,such as other
processed power supply voltage, the
measurement deviation is large.
3Due to the different structure of the socket,
when the zero and live wires cannot be
distinguished by the induction mode, it can be
switched to the AC voltage detection mode,
which can generally be distinguished according
to the voltage detected by the electric pen.
4When the induction mode is used to
distinguish the zero and live wires: if the zero
and live wires are very close, separate the two
wires as far as possible for detection; if it is
impossible to separate them, distinguish them
according to the strength of the detected signal,
the one with strong signal is the live wire, and
the one with weak signal is the zero wire.
5As the detector measurement requires
human contact to form a loop, please ensure
that your fingers can touch the detector keys
well.
6Because the induction mode of the electric
pen has high sensitivity, it can sense the weak
electric field signal, so it is normal to trigger the
induction when the metal detector contact the
object with the weak electric field directly.
7Do not use as a screwdriver.
Auto Power Off
After about 5 minutes without any operation and No
signal detection, the voltage detector will be
automatically shut down to extend the battery life.
Low Battery Indicate
When the battery voltage drops to less than 1.2
volts, the display will display " " symbol. When
low battery tip, please replace the battery.

Replace the Battery
Push off the battery cover as shown below, then
take out the old battery, and install the new battery
according to the positive and negative
indications of the battery.
Warning
To avoid electric shock, do not use a voltage probe
to detect the voltage before the battery cover is
fastened and locked. \n In order not to affect the
detection, please ensure that the human body is
insulated from the ground.
Clean maintenance
Clean with a wet cloth.
Notes: After cleaning, the voltage detector can’t be
used until it is completely dry.

关机。
照明
在开机状态下,短按下开机/照明灯按键,
电筒打开;在手电筒打开状态下,再短按开
/照明灯按键,则关闭手电筒。
无感应信号及无任何操作 5分钟后会自动关
闭。
断点寻找/应模式测量
开机默认感应模式测量状态。
将测电笔的探针放在靠近交流电压源时,
鸣器响;蜂鸣器响的频率有三档,随信号增
强,递增。同时显示屏会显示“——U,
号强时显示HI以此功能,可查找电线
断点。
交流电压探测
开机后,按住接触测量按键,进入交流电压
测量模式,测电笔的探针接触带有交流电压
的导体时,显示屏幕上显示对应的交流电压。
此功能,可检测交流电压大小,根据电压的
大小区分零火线。
电线导通
开机后,右手按住测电笔导通/正极测量按
键,左手捏住不带电导线一端,用测电笔探
针,接触导线另一端,如导线连通正常,
显示显示“——C”蜂鸣器响,如电线开路,
测电笔无反应。
电压正极检测
开机后,右手按住测电笔导通/正极测量按
键,左手负极(如电池负极)用测电笔探针,
接触正极(如电池正极)如正确,则显示
屏显示“——P”蜂鸣器响,如接反,测电笔
无反应。
一般情况下,背光亮红色时,说明被测物体
可能存在危险,需小心操作。
1:请确保人体与大地绝缘,请穿着绝缘
性好的鞋子,或是站在绝缘垫上使用;
体的某一部位接触到带电物体,或者是其他
大面积的导电物体或者是接触到大地,
会使测量结果偏大
2:本产品只能用于测量市电电压,如测
量其他经过处理的电源类电压,误差较大。
3:由于插座的结构不同,当不能通过感
应模式区分零火线时候,可切换到交流电压
检测模式,一般可根据电笔探测到的电压大
小来区分。
4:当使用感应模式分辨零火线时,如果
零火线靠很近时,尽可能将两根线分开来检
测;如实在不可分开,可根据探测到信号
弱来区分,信号强的一根是火线,信号弱
一根零线。
5:因电笔测量需要人体接触形成回路,
所以请确保手指可以良好的接触测电笔按
键。
6:因电笔的感应模式有极高的灵敏度,
可以感应微弱的电场信号,所以在金属探测
头直接接触带有微弱电场的物体时,触发感
应,属正常现象。
7:请不要当做螺丝刀使用。
