VERSATILE DIGITAL MULTIMETER - Accurately measures AC/DC Voltage, DC Current, Resistance, and Diode. This Multimeter is a really useful tool for solving industrial and household electrical issues. Suitable for Household Outlets, Fuses, Batteries (including Vehicles), Automotive Circuit Troubleshooting, Charging System, Testing electronics in Cars etc.

TROUBLESHOOTING WITH Accuracy - This Multimeter has a sampling speed of 2 times per second; Built-in a backlight LCD display with 3 ½ digits (1999 count) 0.6”, and high polarity including negative and positive readings.

ENSURES SAFETY - Double ceramic fuse is anti-burn and protects from overloading.The silicone cover is able to protect the multimeter from failing damage and prevent electric shocks. And low battery indication will be displayed when battery power is low.

SAFETY FIRST: It will send out multiple alarms through sound and light. When the voltage is detected, the tip will send out red light and beep. When the higher the sensed voltage is, or the closer it is to the voltage source, it beeps at a higher frequency. 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.

NON-CONTACT: With NCV inductive probe for AC voltage; Just place the tip near a terminal strip, outlet, or supply cord. When the tip glows red and the pen beeps, you know there's voltage present. The live wire detector can automatically detect the live or neutral wire. Ideal for breakpoint Test. Handy circuit tester for electricians, homeowners.

DUAL RANGE: Detects standard and low voltage (12-1000V AC / 48-1000V AC) for more sensitive and flexible measurements. Press the S button to adjust sensitivity and adapt low range for doorbells, thermostats, irrigation wiring etc.; The NCV sensor automatically recognizes the voltage and displays it on the bar graph.

A SAFEGUARD OF HOUSEHOLD APPLIANCES: Built in Premium LCD Digital Display with Black Character, this test can immediately detect and measure the current voltage by connecting to the switch plug or the other kind of wall socket. It allows you to check on power health of devices for preventing the low voltage damage to your valuable household appliances.

WIDE MEASURING RANGE & LOW CONSUMPTION: Measuring range: AC80-300V, Consume Power: Less than 1W(about every 1200hours consume 1 kilowatt-hour).2 Prongs Flat US Plug with Compact Size Design is ideally applicable to measuring the AC voltage in family, office space, industrial and mining enterprises, etc.

ADJUSTABLE POTENTIOMETER: There’s an Interior Potentiometer for accuracy adjustment. Just use screwdriver to open the outer coving and adjust the potentiometer with small size screw driver. Adjust potentiometer in counter-clockwise when it’s excessive voltage, but if display voltage is too low, adjust potentiometer in clockwise.
