TACKLIFE -The Latest Dual-Range NCV Tester With High- Definition LCD Display

✓Safety Factor Certification:CAT.III 1000V CAT.IV 600V；CE

- What does CAT level mean to users?

It means a commitment to the personal safety of customers!

Voltage values behind CAT indicate the upper limit of their ability to be subjected to voltage shocks.

- Static electricity on the human body can also cause the response of the tester,because it's sensitive enough to ensure the safety of customers.

✓Adjustable Sensitivity

✓High-definition LCD display

✓Identification of Live/Null Wire

✓Low-battery Indicator

✓Portable Pencil Hook

✓White LED Flashlight - Energy Saving, Convenient

✓High and Low Voltage Signal Indicator

✓Buzzer Alarm - Loud and Sensitive

✓Auto Shutdown

✓Good Sensitivity of NCV Sensor

Live Wire Testing

When the sensor end of the measuring pen is close to the object to be measured, the fast-paced buzzer alarms with its red indicator flashing quickly, and the LCD shows red light, indicating that the tested line is a LIVE WIRE

Null Wire Testing

When the sensor end is close to the object to be measured, the slow-paced buzzer alarms with its red indicator flashing slowly, and the LCD shows green light, indicating that the tested line is a Null Wire

Switching on/off

Tacklife VT02 is an improved version which retains only two buttons, making it EASY to use. - Press the power button for 2 seconds to switch it on, and press the same button once to switch it off.

High-Definition LCD Screen

- When testing the voltage, the brightness bar on the high-definition LCD screen will tell you the voltage intensity; The screen will light up in red/green to distinguish the Live/Null Wire

- High/low sensitivity:When first turned on, the tester is in low sensitivity mode(48-1000V) by default. Press and hold the Sensitivity/LED button until the LED light is turned on, and then press the same button again to make the "S" button light up, the high sensitivity(12-1000V) was chosen.

Safe Non-Contact Voltage Probe

- The electricity can be measured without touching the measured object, which greatly helps your safe use, then indoor wiring and wiring detection is no longer a concern for you.Moreover, the sensitivity of NCV probe is high enough and the response of measuring electricity is very fast.

- Note: Please do not use the tester to test a bulb exists in a closed circuit, because there is no leakage of current nearby, the electric field is very weak, and then the electricity can not be detected.

Bright LED Flashlight

- When the circuit in your house suddenly goes wrong at night and it's dark all around, this pen with a bright LED light installed on the probe will be your most helpful friend at that time. - Under dark conditions, you can press and hold the sensitivity / flashlight button for more than 2 seconds to turn on/turn off the LED Flashlight, and then you can quickly use it to look for the problems in the circuit. LED flashlight saves power and provide convenience.

Portable Pencil Hook

- Convenient and friendly design. For it's weight or overall design, this pen is as easy to carry as a regular pen. The design of the pencil holder enables you to carry the pen anywhere you want. You can take it away directly in your pocket after use, without occupying much space

▲Please install the battery correctly and pay attention to the positive and negative electrodes. Error installation will make the voltage tester pen unable to work normally.

Intelligent Electricity Consumption Reminder

Auto Power Off - After about 3 minutes without any operation or signal detection, the voltage detector will be automatically shut down to save power, which can also extend the battery life;

Low Battery Indicator - It is helpful for you to use the pen safely. When the power of the pen is insufficient, the LCD screen will give relevant prompts to remind you to replace the battery in time, so as to avoid using the pen when the pen has no power.

User questions & answers

Question:	Will this work on Christmas lights
Answer:	That depends on what type of light you have. Does your christmas lights power by batteries (DC), or AC source? What about the range of working voltage output? Does it within AC 12V-1000V? a.If your Christmas lights are powered by battery, that is DC voltage, this AC voltage tester will not suit for DC voltage; b. If your Christmas lights are powered by plug in socket, that is AC voltage, this tester could test AC 12-1000V. Please note: 1. This is a AC Non-Contact Voltage Tester, range (AC 12V-1000V), will not suit for DC voltage; 2. Due to the wide measurement range (AC 12V-1000V), there will be an alarm when there is live equipment or static electricity nearby. 3. It will flash and beep when the Non-Contact Voltage Tester is close to AC voltage Source during the specified voltage range even though without touch the measured object. As more closer, it will beeps louder. You can distinguish the Hot and Null Wire through different frequency alarm sound and LED Indicator. You could refer the video in the listing.

Question:	Can it detect load? My other sensor gives a positive on a cable even though the light switch is off
Answer:	If there is power on the cord you will pick up a voltage signal.
Question:	does this tester have a beeping sound whence detecting voltage
Answer:	YES! The Neoteck Non-Contact Voltage Tester DOES BEEP when voltage is detected! The beeping is very convenient to have when sticking the tester in a space where one has a hard time seeing the light-indicator.
Question:	What is the diference touching positive,negative an neutral
Answer:	This product only could test positive and test whether the wire has high voltage or not. If you need to distinguish positive, negative and ground wires, you could purchase this: B0819VNT6V.

Tips of Non-Contact Voltage Tester:

• Due to the wide measurement range (12V-1000V), there will be an alarm when there is live equipment or static electricity nearby.
• It will flash and beep when the device is close to AC voltage greater during the specified voltage range even though without touch the measured object. You can distinguish the Live and Null Wire through different frequency alarm sound and LED Indicator.
• The video in listing in reference.

Live Wire Testing

• The buzzer gives a quick and frequent warning when the end of the tester is near the object to be measured.
• The red indicator light flashes quickly. This indicates that the line under test is a live line.
