Baijian Testing is mainly engaged in textile, insulation, cosmetics, food, hardware industry related product testing, as well as providing product certification services, but also in the broadening of the scope of the testing industry, the laboratory issued a report can be stamped CNAS/CMA/CAL qualification seal, the report is true and effective.
Report qualification: CNAS, CMA, CAL, etc.
Testing costs: Quotation sample size according to customer needs and experimental
complexity: Choose to send samples or come to the door according to the sample size
Standard No.: JB/T5871-1991 Chinese Standard Name: Line Charging Current Opening and Closing Test for AC High Voltage Circuit Breakers Chinese Standard Classification No.: K43 Part Replacement Standard: The original standard number GB4876-1985 has been replaced by the following standard: IEC56-1987, non equivalent; IEC427-1989, non equivalent use 1> How to measure the voltage of a battery: The voltage of a battery can be measured using a pointer multimeter or a digital multimeter. Method: 1. Select the range of the multimeter (1.5V, 3V, 6V, 9V); 2. Connect the red lead to the positive pole of the battery, and the black lead to the negative pole of the battery. 2> How to measure the charging and discharging current of a battery: To measure the current of a battery, still use a pointer multimeter or digital multimeter: Method: 1. Select the mileage of the multimeter (100mA, 500mA, 1A, 5A); 2. Connect the multimeter in series in the circuit; 3. The red pen allows the current to flow in, while the black pen allows the current to flow out; 4. Electrical appliances must be connected to the circuit, and the ammeter must not be directly connected to both ends of the battery
