Material: plastic
Working range: voltage 3.5V - 7.0V; current 0A - 3A
Resolution: voltage 10mV current 1mA
Error: voltage < ±="" 1="" percent="" current="">< ±="" 2="">
Full-scale voltage drop: 200mV ( when measuring current )
Working temperature: 0 - 60 Deg.C
Use:
Very simple and practical small instrument:
◆Small and portable, no need for external power supply and other ancillary equipment, plug and play
◆It can detect any USB output power, charger, computer USB, car charger and mobile power
It can easily measure the no-load voltage of the USB port, the load voltage and the current when the device works, and judge the charging
Whether the performance of the device and the charging cable meets the requirements
◆Simple operation and wide application range: USB voltage and current are alternately displayed, and the test results are clear and clear, which are suitable for factories, laboratories and ordinary users
