4-in-1 DC Multimeter: with 1.0 grade measuring accuracy, it combines Voltage, Current, Power and Energy measurement in one combo, super compact and lightweight that can be portable and easily used. Unique Voltage Alarm Function: the backlight and voltage value will flash simultaneously if the testing voltage is beyond alarm threshold (6-90V factory alarm value), and it can be set if neededData Storage Design: it is designed to automatically storage the last testing data when suddenly powered off and the energy value can be reset by a short press after long pressing the function button for secondsSuper Large Digital Display: 51x30mm easy reading LCD screen, clearly displays all testing figures at the same time, while the recessed button used to control the backlight, reset energy value, set voltage alarm threshold and choose measuring rangeBonus Current Shunt: it comes with a 100A/75mV current shunt, suitable for large range measurement, no need to waste extra money to get another one.4-in-1 DC Multimeter is able to measure voltage, current, power and energy of most electrical devices (100A max.), which features high accuracy, low power consumption and easy reading large display. It also functions beyond voltage alarm, energy value reset, data storage, backlight control and measuring range option, suitable used for RV battery, voltage regulator, device detection and replacing various pointer-type electric meters.Specification Working Voltage: 6.5-100V/DCPower Rating: 100A/10000WMeasuring Accuracy: 1.0 gradePower Consumption: 0.2WMeasuring Speed: 2 times/sNet Weight: 190g/0.42lb/6.70oz Meter Dimensions: 9.0x5.0x2.4cm/3.5x2.0x0.9 inch Shunt Dimensions: 10.5x3.0x2.2cm/4.1x1.2x0.9 inchDisplay format: 1.
