DC Ammeter,Digital DC Multimeter 0-90V 100A Voltmeter Ammeter Current Amp Power Watt Capacity Time Meter Battery Tester Monitor with LCD Screen

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