CS-200 intelligent battery internal resistance tester is used to measure the internal resistance of the battery and the battery level of acidification film damaged equipment, hereinafter referred to as the instrument. It is an AC signal of 1KHz is applied to the measured object, by measuring the AC voltage drop across the internal resistance is obtained. (It is different from the principle of resistance measurement multimeter, measure the value of what it is milliohms level, while the measured value is Ohm Meter level; and no resistance multimeter can measure the power of objects, and not only resistance tester No power resistance measurement objects can also be measured have resistance power objects, so the two can not equal) use to determine the size of the internal resistance of the resistance of the deteriorated state of the battery, (generally) lower the resistance of the battery the better the performance. Therefore, the use of the battery internal resistance measurement method is a good way to speed and high reliability. First, ?? Scope 1, mobile phone use nickel-cadmium, nickel-metal hydride battery (group), lithium batteries; 2, lead-acid batteries, and maintenance-free batteries; 3, is also applicable to various types of battery research institutes research trials and manufacturers. ?? Second, safe working practices in order to avoid damage to the instrument or test batteries, please follow the following guidelines: 1 ,? before use, please check the instrument casing for cracks or missing parts. Special attention to the insulation surrounding the connector. 2 ,? check test whether the needle is turned on, if the test pin is damaged or broken behavior, even after the use of this instrument. Two test pins 3 ,? same mounting plate not in contact, to prevent short circuits. 4 ,? Do not use the instrument in explosive gas, vapor or dust near the acidic environment. 5 ,? measurement, battery internal resistance and voltage must be within the scope of the measurement instrument, otherwise inaccurate readings, more than the rated voltage (19.99V) will burn instruments. 6 ,? forbidden instruments to measure the high voltage power supply (eg: 220V power supply or other high-voltage power supply), or peril! ? Third, a comprehensive index ?? ,? Input Power: AC 220V 50Hz 2 ,? ??? degree temperature: 0 ℃ -50 ℃ 3 ,?
