1、FOUR MODES OF OPERATION: CC constant current operation; CV constant pressure operation; CW constant power operation; CR runs with constant resistance. There are three intelligent safety protection in the discharge detection process of the tester, which can monitor the discharge tube status in real time, safe and reliable. External wired NTC thermometers allow for both internal and external temperature measurement 2、TECHNICAL PARAMETERS: 2.4in high definition large color screen blue digital curve version of high power tube digital load meter. With intelligent temperature control dazzling fan, large power, long life, durable cooling fan; 180W high power, 200V wide voltage, 30A large current, strong performance. Meet a variety of experimental detection 3、TEST OBJECTS: The tester supports testing for Android, Type C cables, for Mini and other wires, and displays various test data on one screen. Through the inspection, through the test of various data cables, charger testing, discharge aging, DC power adapter current, voltage, power and other parameters, simple operation, the test is convenient and fast 4、TEMPERATURE CONTROL FAN: 180W load discharge aging test, the tester adopts intelligent temperature control light effect fan design, built in large discharge tube, the temperature is maintained at about 50 ~ 80℃ 5、WIDE APPLICATION: The tester can easily test voltage, current, capacity and other data of various power sources, such as lithium batteries or USB chargers; Powerful, safe and reliable Item Type: Electronic Load Tester Material: ABS Working Current: 0.2~30A Constant Load Adjustment Rate: ±3% + 3 bytes 1. 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 mode 3. 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 charge 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 charge bank is exhausted after the capacity value. 1 x Tester 1 x Adapter 1 x Converter 1 x 4 Interface Accessory 1 x Red Crocodile Clip String 1 x Black Crocodile Clip String 1 x External NTC Temperature Probe 1 x PC Computer Online Cable 1 x User Manual
