The Serplex digital multimeter helps with quick electrical checks at home, in workshops, and during routine circuit testing. This pen type digital multimeter combines a compact probe-style form with non-contact voltage detection for identifying live wires without direct contact. Use it for AC/DC voltage and resistance measurements, with the LCD readout showing test values clearly. The built-in LED light supports visibility when working inside panels, around sockets, or in dim areas. Compared with carrying separate voltage testers and resistance meters, this digital multimeter tester brings common checking functions into one device. The 6000-count display supports detailed readings for everyday electrical inspection. Insert the required battery before use, as the battery is not included. Select the correct measurement function, keep the test leads and probe tip clean, and follow the user manual. Verify operation on a known source before testing an unknown circuit, and switch the meter off after use.
