Automatic Multimeter Intelligent Digital Display Multifunctional Maintenance Electrician Special Portable Small Power Meter Features: With 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-contact voltage test with sound and light alarms; energy-saving and safe. No need to connect wires to measure AC voltage, making it easier to troubleshoot wiring. Overload protection measures are built into the instrument to improve safety performance and maximize user security. The silicone cover protects the multimeter from damage and potential shock. Supports data hold, auto power off, low battery indication, backlit display, and flashlight function. These convenient features make this instrument suitable for daily use by hobbyists, car owners, and homeowners. Easy to use for various DIY applications. How to Use: 1. Remove the rubber sleeve from the back of the multimeter, open the battery compartment cover, and insert 2 AAA batteries according to the polarity markings. Close the battery cover securely. 2. Turn on the multimeter, insert the test leads as indicated, and wait for calibration before beginning measurements. 3. Measure alternating current/direct current voltage, resistance, or continuity by inserting the test leads into the multimeter and connecting them to the device under test. The multimeter automatically detects the measurement type without manual selection. Note: Do not use test leads when using the NCV (non-contact voltage) function.
