Item Type: Electronic Load TesterMaterial: ABSWorking Current: 0.2~30AConstant Load Adjustment Rate: ±3% + 3 bytes1. Rapid Application Method of Constant Current Mode: When the product is energized and in the state of stopping discharge, long press the set button, and CC on the display interface starts to pulsate. At this time, short press the Add or subtract button to adjust several modes of cyclic display of CR-CP-CVCC. After selecting the corresponding functional mode and waiting for blinking to stop, the system saves and enters this functional mode. Then adjust and turn on and off discharge in the same way as the upper section constant current mode3. Detection Methods And Skills of Battery Capacity: 5. Capacity Measurement Methods And Skills of Mobile Power Supply: First of all, the charging bank is fully charged, and then the load capacity is cleared to zero, start to access the load and set the discharge value to discharge, until the recharge bank is exhausted, then read the cumulative capacity and electricity value on the display screen, this is the approximate value of the capacity and electricity of this charging bank, because this product internal memory function, Therefore, the discharge process can be completed in one discharge, but also can be divided into several discharge, until the power of the recharge bank is exhausted after the capacity value.Package List：1 x Tester1 x Adapter1 x Converter1 x 4 Interface Accessory1 x Red Crocodile Clip String1 x Black Crocodile Clip String1 x External NTC Temperature Probe1 x PC Computer Online Cable1 x User ManualNote:1. Before use, ensure that the maximum power of the set discharge point is within the range. Overpower will be automatically protected.2.
