Automatic Multimeter Intelligent Digital Display Multifunctional Maintenance Electrician Special Portable Small Power Meter Features: With the intelligent auto mode, the smart digital multimeter quickly switches between all measurement tasks, including alternating current / direct current voltage, resistance and continuity, without the need to select a mode or range. It makes measurement easy, fast and accurate. Completely safe non- voltage test with sound and light alarms;-saving and safe. You don't need to connect wires to measure voltage AC wires, making it easier to troubleshoot wiring. Overload protection measures are used inside the instrument to improve the product's security performance and maximise users' security . The silica gel cover protects the multimeter from damage and potential shock. It supports data hold, auto power off, low battery indication, backlit display and flashlight. All these convenient features make this instrument sufficient for daily use by hobbyists, car owners and homeowners. Easy to use and enjoy unlimited DIY pleasure! : How to use 1. Please take off the rubber sleeve the back of the multimeter, open the back cover of the battery, and put 2 AAA batteries into the battery compartment according to the polarity markings. Close the battery cover. 2. Turn the power of the multimeter, insert the test leads according to the prompts, and enter the test when the ends of the test leads are in for calibration. 3. Measure alternating current / direct current voltage, resistance or continuity. Insert the test leads into the multimeter and connect them to the ends of the DUT. The multimeter automatically measures without user selection. Note: No need to use test leads if you want to use the NCV function.
