EJ-BC22 can be used to measure percentage and AH of remaining capacity, DC positive and negative bidirectional current, DC voltage, DC positive and negative power, DC positive and negative bidirectional accumulated electric energy.
Alarm flashing function, it will alarm and flash to draw your attention when the real voltage is higher or lower than preset alarm voltage and real current is higher than preset current. the preset voltage and current could be adjusted as you need. it will also alarm and flash to draw your attention when the remaining capacity of battery is low and the battery icon will keep flashing that means you need to charge for your device
It will automatically fill the capacity of the battery when it is full voltage,
It has the function of clearing current and accumulated electric energy data and the function of storing data when power-down. The capacity of the battery and accumulated electric energy will be saved automatically when power-down.
EJ-BC22 is suitable for lithium batteries, lithium iron phosphate batteries, lead-acid batteries, and nickel metal hydride batteries which voltage is from 0V to 300V.
The EJ-BC22 with 3 wires, allows to be powered by a wide voltage range and has a wide voltage measuring range. If the measured voltage is DC5~90V. you can use two wire system connection to make it work, which is easy and simple. There are 3 wires on the back of meter, as following:
The black wire is for power supply-
The red wire is for power supply+. ( Noted: power supply range must be DC5~90V, or this meter will be burnt.)
The yellow wire is for the input lead wire of the measured voltage, it has to be connected to the lead wire of the measured voltage.
