【 Laptop Charging Monitoring 】 When powering the laptop, prepare two Type-C cables and connect this meter as shown in the following figure for testing

The screen supports 360-degree arbitrary rotation to meet the reading requirements at any Angle. The menu bar corresponding to the long key can rotate the screen, allowing various digital devices to be inserted at any Angle and read in the forward direction, making the measurement more convenient.

Real-time current and voltage curve display, with two modes and two curve detection. Voltage and current curve detection; D+D- curve detection enables real-time viewing of current and voltage fluctuations

【 Wire Resistance Measurement 】 After inserting the data cable, the screen of the tester turns black, indicating that the voltage difference is too large

Test various USB chargers and monitor their performance stability. Play with and test various USB chargers. Just pair them with a constant current load and you can easily conduct the tests

【 Power-off Memory Data Storage function, suitable for testing the capacity of various power banks 】 It is equipped with a power-off storage function. When the power bank is powered off, it can store the capacity data of the power bank, which is convenient for subsequent viewing and capacity testing of the power bank. When the power is cut off, the current capacity is temporarily stored. When the power is turned on again, the currently used capacity will be accumulated. If it is not needed to be accumulated, it can be manually cleared.

【 Test Type-C/ Android Data Cable 】 Insert the Android data cable into the Micro USB input port of the "Juwei A3 Color Screen Meter", and then insert the adjustable constant current load into the USB output port of the "Juwei A3 Color Screen Meter" for adjustment and testing

【 Test various data cables and monitor mobile phone charging data in real time 】 Charge your mobile phone, test and monitor the charging data. The larger the current, the better. Monitor the charging status data of your mobile phone in real time. Easily test the quality of the data cable. Simple operation, convenient and safer measurement.
