Button Function Instruction:

This tester has 0 and 1 two data groups; and data groups are switched by pressing the key.

When data group is the 1 group, the current capacity and energy will be stored after power off. And the stored values will be accumulated after power on. When the data group is the 0 group, the current capacity and energy will be stored after power off; when power on next time, the stored capacity and energy are blinking displayed. But when the new capacity is up to 0.01Ah, the stored capacity and energy will be covered, and the values will start over. At the two data groups, the accumulated values can be cleared to zero by keeping pressing the key.

Zero calibration operation

With the aging of components and influence of ambient temp, there might be tiny error for the current reading, especially when measuring low current. To calibrate it: 1, power off the meter.2, disconnect the load. 3 press and hold the front button .4, power on the meter.5, release the button when you see “AAA” on the screen. Done

Using Isolated Power Supplyto power the meter

The two power supplies must be isolated and don’t have any connections between them. The voltage of the isolated power supply must be less 60V

Using system to power the meter

The black thin wire connects nothing and you should use insulator wrap it to avoid short circuit.

Using DC-DC converter to power the meter

The black thin wire connects nothing and you should use insulator wrap it to avoid short circuit. The DC-DC converter must be common cathode structure.
