NJTY 600A AC/DC Digital Clamp Meter with Temperature Auto Ranging Multimeter with Audible Continuity Beep True-RMS Clamp Meter with Diode/NCV/Voltage/Current/Resistance/Frequency/Capacitance/LoZ/VFC Tester Meter   A versatile and practical clamp meter tailored for professionals, maintenance engineers, electricians, home DIYers, etc.  Features: [Versatile Meter]Applied for measuring AC/DC voltage, LoZ low-impedance, AC/DC current, resistance, capacitance, temperature, diode, frequency, VFC, continuity and NCV. [Accurate Measurement]High-speed digital processing unit with 6000 counts features speedy readings and true-RMS calculation up to AC 1KHz. [Live/Null Wire Detector]Non-contact detects the live/null line and alerts you with a beeping sound. Quickly checks shorts or broken circuits in all types of electrical devices. [Easy e]Beeps as it gets closer to AC fields; audible continuity buzzer; low battery indicator; data hold button and selector dial; auto sleep mode; comes with batteries and a case. [Backlit & Flashlight]Designed with backlit and flashlight to ensure sharp read-out and good visibility in the low-light or dark area. Note: *Batteries are not included. *Do not use it on over 600V AC/DC when testing voltage; not over 250V AC when testing frequency, resistance, continuity and diode; not over 600A when testing current. *Auto sleep mode only turn off the LCD screen after no operation in 15 minutes, you can turn on the meter immediately by pressing any buttons under sleep mode. But selector dial should be twisted to 'OFF' to totally turn off the product if the clamp meter is not in use for a long time. *Please read the user manual carefully before use.
