0-90V 0-20A DC Digital Multimeter LCD Voltmeter Ammeter Volt Amp Watt Time Capacity Meter + Relay

0-90V 0-20A DC Digital Multimeter LCD Voltmeter Ammeter Volt Amp Watt Time Capacity Meter + Relay

Features:
- Bidirectional Detection: this bidirectional meter can detect and display current to charging and discharging. Note: it can not detect current of two directions at the same time
- Power Off Memory Function: this battery tester can automatically save the parameters when the display power off; if the monitor module also needs to power off, press OK button can save the parameters
- Clear Function: clear function of time and AH value without affecting the measurement
- Multimeter: this multifunctional meter can detect DC voltage, current, capacity of charging and discharging, time, power and other physical information at the same time
- LCD Color Display: it can be seen even under sunlight; LCD display will automatically turn off after two minutes if the current is less than 50mA, pressing any key can turn it on, or it will wake up automatically when the current is greater than 50mA
- Application: it is quite suitable for monitoring the output voltage and current, as well as applications such as battery charge and discharge
