1. The matching sampler must be connected in series to the negative circuit of the battery pack. The B-end of the sampler is connected to the negative electrode B - of the battery pack, and the P-end is connected to the negative electrode P -/C - of the charging and discharging point

2. Take a 0.3-0.75mm piece ² The red wire connects the positive electrode of the battery to the sampler B+for power supply to the electricity meter.

3. Connect the sampler to the meter with a shielded wire, confirm it is correct, and then power it on.

4. Wiring principle: Ensure that all current flowing through the battery passes through the sampler!
