1、FULL FUNCTIONING: This meter is an intelligent True RMS auto range high accuracy digital multimeter with intelligent and professional measurement functions. Complete functions with gear and analog bar display. 2、AUTOMATIC IDENTIFICATION: After starting, the measurement will automatically identify the object to be measured, and realize the intelligent anti burning of voltage, which is suitable for professionals and novices. 3、SUPPORT NCV FUNCTION: NCV non contact voltage detection and insulation test are safer. It is both multimeter and test pen, and the single test lead is inserted into the socket to judge the neutral wire and live wire. 4、WIDE RANGE OF APPLICATION: 4000 counts voltage resistance tester is suitable for household circuit detection, industrial circuit detection, office circuit detection, outdoor operation circuit detection, etc. 5、SMART MEASUREMENT MODE: This measurement mode is defaulted at power on. In this mode, you can measure DC voltage, AC voltage, resistance, on off, and the meter automatically recognizes the measurement signal. Item Type: Digital Multimeter Model: HT124B Material: ABS Battery: 2 x 1.5V AAA Battery (Battery Not Included) Application: Home circuit testing, industrial circuit testing, office circuit testing, outdoor work circuit testing Support Language: English Basic Parameters: 1.
