KWS-1902C Type-c Two-way tester Color screen USB current and voltage test table
The KWS-1902C features a 0.96″ 1PS HD colour LCD with a 160 degree wide viewing angle, high brightness and long working life.
Connections as follows Can be used in both directions
High brightness, 160° wide viewing angle, IPS-grade full colour display with rich colours, long working life More expensive, quality assured.
Fast charging recognition is widely compatible
KWS-1902C supports QC2.0, QC3.0, PD, and SAMSUNG fast charging protocol recognition, so you can know the charging status of your phone!
4-bit precision, more accurate measurement
The KWS-1902C uses professional instrument sampling circuitry internally. Together with a unique accuracy algorithm, the ensures accuracy and stability at both hardware and software level!
Guaranteed data storage in the event of a power failure
The KWS-1902C comes with a power failure storage function. When the mobile power supply is disconnected, it can store capacity and energy data for subsequent viewing and easy energy measurement of the mobile power supply.
Mobile power supply capacity calculation method.
Mobile power fully charged connected to KWS-1902C (data cleared first) with the appliance and discharged to stop output. Method 1: Mobile power capacity = KWS-1902C measuring mAh data X output voltage ÷ battery voltage ÷ efficiency Method 2: Mobile power capacity = mWH measured by KWS-1902C ÷ battery voltage ÷ efficiency (General mobile power output voltage 5V, battery voltage 3.7V, efficiency about 85-90%) Power up again after a power failure to read capacity and energy data (Please note that low-end USB testers do not have a power-off storage function, so please shop carefully!)
Test load discharge power
Get a clear picture of the load’s impedance and current discharge power Better understanding of the load’s range of application, easier and faster to use
Instructions for key operation
1. Single short press to change the display page once 2. Quick double click on the key to rotate the display 3. Press and hold the key for 3 seconds to clear the saved data 4. Current and voltage calibration method. Press and hold the key with a standard voltage of 5.000 V. When the screen shows Factory setting, the key is released and the product is automatically calibrated. (Note! The product must not be connected to any load during calibration)
