V-TECH KCX-017 LCD USB 3V-7V Voltage Current Detector Power Tester

Garansi: 1-minggu Keterangan lengkap: goo*gl/NBwEa4 KCX-017 LCD USB Voltage Current Detector Mobile Power USB Charger Tester Meter Description: This test can be a USB charging current, voltage, discharge capacity, intelligent devices. It can be very easy to find digital device charging problem. Tester three dimensional size 60 * 28.5 * 15mm (without cable), about 15 cm length of the line The only button on the tester is used to view and test data switch, the tester can store 10 groups of test data Specifications: 1. Input Voltage: 3V - 7V current: 3 .4A 3. Parameters that you can test: Voltage of battery. Current of battery, value of discharging capacitor.(Total ten parameters) 4. Communication function: Yes 5. Parameters adjusting function:Yes. Equipment for parameters adjustment: One electronic load, one constant current source. Voltage of constant current source should be set to 8.5V There are 3A, 2A, 1A and 0.3A models for current adjusting. Here is a example for 3A: When you set electronic load at 3A model, the current will be adjusted step by step. It will cost you about 10 seconds and you can see the result changing procedure in the LCD screen. When you see the 3A result shown in LCD screen, the adjustment process is finished. You can shut off the electronic load and the parameters will be saved automatically. the data: Push the button until the parameters changed to next sets of parameters. Then release the button. Then the next sets of parameters will be started and they will start from zero. 7. Check the parameters: Quick beat the button double times(within 0.5s), then it is checking model. The LED background will be you can see the next set of parameters in LCD screen. Quick beat the button double times again, you release the parameters checking model. LED background be be light with flash. 8. Ngak muat, baca di link diatas
