Infrared Thermometer: The PV digital multimeter can also be used as infrared temperature gun. Uses an upgraded sensor for more accurate temperature measurement. It can show both the real-time temperature and MAX temperature at the same time, the laser pointer can be used as a target location point.Dual Mode Power System: The smart multimeter tester has 2 separated power systems, one is rechargeable lithium battery, the other is 2 alkaline batteries, you will never worry about no power problem.High-precision Measurement: 20,000-word photovoltaic multimeter high-precision four-and-a-half-digit test. Min resolution of current 0.1A Min resolution of voltage 0.01mV. DC/AC voltage can be measured up to 1499.9V/749.9V.Smart Mode: digital multimeter tester can automatically measure ac voltage, dc voltage, resistance and continuity with the best solution. All of this functions measurement can be done manually as well.Amp Test Automatically Activation: Electrical Amp Tester with automatic activation of the DC AC current test function. Automatic selection of range measurement. (Test leads need to be inserted into the amp port)
