DollaTek Digital Multimeter DC 0 90V 100A Voltmeter Ammeter Power Watt Capacity Time Meter Battery Tester Monitor with LCD Screen Hall Effect Sensor

Two-way current detection, for users who detect load and discharge, can automatically identify and detect bidirectional current without changing the wiring direction. The extinction memory function can memorize the AH number before extinction after extinction, which is convenient for observation and measurement. The function of clearing time and AH number does not affect the next measurement. The number AH can be filled without affecting the direct flow measurement. Voltage, current, load capacity, AH number, WH number, time and power are displayed simultaneously and the information displayed is complete and clear. With the output stop function button, a flexible output to turn the output on or off (requires a relay). With over voltage, over current, over voltage, time limit, overload and other protection functions, you can perform online calibration. The LCD display can be turned off manually or automatically after reaching the minimum value for one minute. The current is detected by the Hall sensor, and the current through the sensor hole can be passed. The current in both directions can be detected, which is safe and convenient.
