2. Power-off memory function, after power-off, it can memorize the AH number before power-off, which is convenient for observation and measurement. 3. The time and AH number reset function will not affect the next measurement.
4. The number of AH can be topped up without affecting the direct discharge measurement.
5. The voltage, current, charging capacity AH number, WH number, time and power are displayed at the same time, and the display information is comprehensive and clear.
6. With an output shutdown function key, the output can be turned on or off flexibly.
7. With overvoltage, overcurrent, overpower, time limit, overcharge and other protection functions. 8. It can be calibrated online, which is convenient for customers to correct errors in time.
