Features: Concise Appearance: Compact and portable body, three-dimensional design, with a full-wrap silicone cover, protective and comfortable to grip. The combination of silicone cover and EVA storage bag, easy to carry, does not occupy the space, say goodbye to the traditional bulky and difficult to carry. 3.5-inch Color Display: IMD process screen, 3.5-inch large-size LCD color display with large font, very suitable for middle-aged and elderly electricians to use, easy to operate. Intelligent Auto Identification: Auto ranging, high-speed chip, no need to shift, say goodbye to cumbersome, no delay. Pluggable pen design, the current, voltage, resistance, and continuity will be automatic identification. Insert the test pen into the current jack for automatic switching. Multi-functional Design: It can be used to measure AC/DCvoltage, AC/DCcurrent, resistance, capacitance, diode, on-off, frequency, duty cycle, and non-contact infrared temperature measurement. Support True RMS 9999 counts, NCV non-contact measurement, LIVE wire firewire judgment, VFC inverter voltage test, laser level indication, V-alert AC voltage detection, V-alert alarm, two sensitivity adjustment, battery test, data storage, automatic shutdown, and night illumination function. LED & Diode Test Function: Support LED light-emitting diode test and light up the light-emitting LED within 16V, test the LED's operating voltage and current, test the fixture radiator temperature and surface temperature of LED, overhaul the control circuit boards of the LED lighting system, and can also be used in the automotive lighting system. Cover various types of diode tests, such as rectifier diodes, voltage regulator diodes, and light-emitting diodes, with a maximum test voltage of about 16V. Infrared Temperature Measurement: Non-contact infrared temperature measurement mode, temperature dual-screen display, you can see the maximum temperature value on the screen during the scanning process, non-contact testing of the maximum temperature of the current wiring bus connection, to find out whether there is a false welding or loose. Laser Level Indicator: It can be used on-site as a target positioning point to facilitate communication between field personnel, to meet the overhaul of cat 600V high safety standards 380V power distribution box, and global testing and maintenance. Power Supplying System: Adopts dual-mode power supplying system, support powered by the built-in 3.7V lithium battery or 2 AAA alkaline batteries (not included) to meet various needs. The multimeter prioritizes the use of the lithium battery for power supplies, after detecting the lithium battery power depletion, it will automatically switch to dry battery for power supplying. Widely Appications: Widely used in the electrical testing industry, electrician industry, electronic overhaul industry, LED industry, auto repairing industry, and so on.
