Testermeter-ZHY-2000 lithium battery internal resistance tester internal resistance tester
Description
| This instrument is used to measure the internal impedance and voltage of the battery, it is to apply 1KHz AC signal to the measured object, and obtain its internal resistance by measuring its AC voltage drop (it is different from the principle of measuring resistance by multi-meter, it measures the value on the milliohm level, while the multi-meter measures the ohm level, and the multi-meter can only measure the resistance value of the object with no power supply, while the internal resistance meter can not only measure the resistance value of the object with no power supply, but also measure the resistance value of the active object), it determines the quality of the battery by determining the internal resistance. The internal resistance meter can not only measure the resistance value of passive object, but also the resistance value of active object), it can determine the advantages and disadvantages of the battery by measuring the internal resistance. It is not only fast but also highly reliable. Its biggest advantage is to be able to set the range of test parameters, and the microcomputer system can automatically alarm if the measured result is not within the set range. To eliminate the error of human misjudgment and misinterpretation, to ensure product quality. This is also the difference with the ordinary internal resistance meter. |
Application
1. Nickel-cadmium and metal hydride batteries (batteries) used in cell phones, lithium batteries, dry batteries. 2, lead-acid batteries and maintenance-free batteries. 3, can also be applied to various types of battery research and testing of scientific research units and manufacturers. |
Safe Working Guidelines
To avoid damage to the instrument or the battery under test, please follow the guidelines below: 1. Before use, check the instrument's case for breaks or missing accessories. Pay special attention to the insulation near the connectors. 2, Check whether the test pin is open or not, if the test pin is damaged or disconnected, please change before using the instrument. 3, Two test pins on the same fixed plate should not be in contact with each other to prevent short circuit. 4. Do not use the instrument near explosive gases, vapors, acidic environments or dust. 5, when measuring, the internal resistance and voltage of the battery must be within the range measured by the instrument, otherwise the reading will not be accurate, more than the rated voltage (19.99V) will burn the instrument. 6, It is strictly prohibited to measure the instrument with high voltage power supply (e.g. 220V power supply or other high-voltage power supply), otherwise the consequences will be borne by you! |
