: With an LED flashlight function that is convenient for use in the dark, it can also be used as an emergency light in an emergency. : The HANMATEK non-contact AC tester can adjust the gear in 9 steps, and the detection range can be freely switched between 12-1000v and 90-1000v. Two red lights, two green lights and one green light respectively indicate high, medium and low signal strength, and the buzzer sounds different alarms. The test pen lights up the corresponding signal strength indicator depending on the detected signal strength. : When the AC voltage is detected, the sensor indicator lamp of the tester blinks. : This test pen has NCV sensor, you can detect the presence of AC voltage by simply pressing the power switch and bring the probe of the test pen close to the power socket or live line. We provide 36-Month after sale service, Please feel free to contact us if you have any concerns. High Voltage Alert to warn you of voltage above 90V, the screen turn red and the safety symbol on the screen shines.ĬOMPACT DESIGN: Bright LED flashlight for work in dim ares Low-Power-Indicator when battery voltage is below 2.5V Automatic Power Off after 3 minutes without operation or signal detection Pocket-sized, pen hook allows you to carry it in your shirt pocket. SECURITY LEVEL: IEC rated CAT III 1000V CAT IV 600V, Meets CE requirements The electrical tester is safely double insulated. The NCV sensor automatically recognizes the voltage and displays it on the bar graph. Press the S button to adjust sensitivity and adapt low range for doorbells, thermostats, irrigation wiring etc. Handy circuit tester for electricians, homeowners.ĭUAL RANGE: Detects standard and low voltage (12-1000V AC / 48-1000V AC) for more sensitive and flexible measurements. The live wire detector can automatically detect the live or neutral wire. When the tip glows red and the pen beeps, you know there's voltage present. NON-CONTACT: With NCV inductive probe for AC voltage Just place the tip near a terminal strip, outlet, or supply cord. At the same time, the screen will be red or green, red means high voltage and live wire are detected, green means low voltage and null wire are detected. When the higher the sensed voltage is, or the closer it is to the voltage source, it beeps at a higher frequency. ![]() When the voltage is detected, the tip will send out red light and beep. As Bruce Kuhn, Klein’s director of product development, test and measurements products, told us, “If you make a tester like this sensitive enough to detect voltage on the ‘outside’ of a tamper-resistant outlet, it will be too sensitive in a crowded electrical box that contains several hot wires.” 2 Because the NCVT-3 is designed to detect standard and low voltage, it picks up the standard voltage when placed at the openings of a live tamper-resistant outlet, but from a distance, displaying it as low voltage, still confirming that the outlet is live.SAFETY FIRST: It will send out multiple alarms through sound and light. With these outlets, a traditional non-contact voltage tester doesn’t always work because it can read only standard voltage. To insert a plug in one of these outlets requires equal pressure on both prong openings (it’s a safety issue for children). ![]() The reality is that because it can read low voltage, the NCVT-3 can still pick up the current from the outside of the outlet, which is essential when dealing with the tamper-resistant outlets now required by electrical code. ![]() At first glance, this may seem like a problem, seeing as most other non-contact testers read power from an outlet only by being inserted into one of the openings. The NCVT-3 is unique because it cannot be inserted into an outlet. According to the company, the tool can also handle a drop of up to 6½ feet, which isn’t bad considering it’s a delicate piece of electronics. For a tool that’s often used in dim basements-or situations where the lights aren’t working-this is a minor but very helpful feature, and the Klein was the only model we tested that had this functionality. But the most useful feature is actually its bright LED flashlight, which can be operated independently of the voltage tester. The controls on the NCVT-3 are intuitive, the display is clear, and when testing it in a breaker panel full of live and dead wires, it was sensitive enough to read a dead wire from a short distance without giving us false positives from nearby live wires. This feature also makes it compatible with tamper-resistant outlets, which are now required by electrical code. And unlike some models we tested, it can automatically tell the difference between the two. The Klein NCVT-3 is a dual-voltage model, so it registers both standard voltage (house wiring) and low voltage (like irrigation, doorbells, thermostats).
