ZOYI ZT-DB02 Voltage Tester, Non-Contact Voltage Tester, AC 12V-1000V/48V-1000V Dual Range, Live/null line Tester, Electric Tester with flashlight,Wire Breakpoint Finder, Buzzer Alarm device.

【Non-contact measurement】AC voltage NCV induction probe, put the probe end close to the power supply and voltage, if the distance is closer, the frequency of flashing red lights will be higher, and there will be a high-frequency beeping sound, which means that there is voltage, The live tester automatically detects live or neutral, is ideal for break-point testing.It is a convenient circuit tester for electricians and homeowners.

【Precise dual-range measurement】Dual-range measurement (48V-1000V/12V-1000V AC), adjusted according to the usage scene, the measurement is more accurate, the default low-sensitivity measurement mode (48V-1000V AC) when powered on, press the S key to enter High-sensitivity measurement mode (12V-1000V AC), suitable for low ranges such as doorbells, thermostats, and irrigation wiring.

【Efficient】Press and hold the switch key for two seconds to power on, as long as the voltage is detected, the red light strip in the test pencil will flash, and a buzzer will sound at the same time. When not in use or no voltage is detected, the test pen will enter the sleep state, and it will automatically shut down if there is no operation or no signal detection within 15 minutes.

【Small, Lightweight, Durable Design】LED flashlight, suitable for use in dim environment; Two AAA 1.5V power supplies, low voltage tips below 2.5V; Convenient clip, fits securely into your pocket, compact design, convenient and practical.

【Safety level】CAT II 1000V volt level provides extended operations and protection, and meets CE requirements. The screw wire cover with the O -shaped ring can ensure the prevention of dust and water, and that the best effect is to tighten the back cover of the battery.
