Features 1、Multifunction: Accurately Measures AC/DC voltage, resistance, continuity, and diodes, etc., suitable for electrician test, household use, automotive, industrial electrical problems. 2、Battery Test: Connect the red test lead to the positive terminal of the battery to be tasted, and the black test lead to the negative terminal of the battery. 3、Non-Contact Voltage Test: Place the non-contact voltage induction zone of the meter close to the live wire of the AC voltage; The non-contact voltage induction indicator will light up and you will hear the beep sound, indicating that there is AC voltage on the live wire. 4、AC/DC Voltage Measurement: Connect the test probes to each end of the voltage to be measured. Read the measurement results from the display. When measuring DC voltage, the display also shows the voltage polarity of the test point of red test probes. 5、Diode Test: Connect the red test probe to the anode of the diode to be measured and the black test probe to the cathode of the diode to be measured. The reading on the display is an approximation of the forward voltage drop of the diode. Reverse connection will show /"OL/". Specification This portable digital multimeter has stable performance, high accuracy, low power consumption and novel structure, which is safe and reliable, making it an ideal measuring instrument for most users.
