When using a battery load tester, the following precautions should be taken to ensure the accuracy and safety of the test:
1. Preparation before testing
① Environmental inspection: Ensure that the working environment of the tester meets the requirements and should be placed in a dry, well ventilated space to avoid the presence of moisture and harmful gases. Specifically, there should be no obstacles within 4-5 meters before the inlet and outlet of the equipment.
② Equipment inspection: Before use, carefully check whether the testing instrument is intact, including whether the power connection is firm, whether the circuit insulation is good, etc., to avoid electric shock or fire accidents.
③ Battery preparation: Before testing, it is necessary to eliminate surface contamination, oxidation, and other conditions on the battery, usually using a dry cloth to clean the surface. At the same time, confirm whether the battery voltage and current meet the requirements of the tester.
2. Connection and Settings
① Correct connection: When connecting the tester, be sure to first check the positive and negative terminals of the battery and ensure that they are correctly connected to the corresponding interface of the tester. When connecting, pay attention to the stability of the wiring to ensure that the current can pass smoothly.
② Parameter setting: Set the test parameters according to the instructions on the instrument, such as discharge current and time. When setting parameters, reference should be made to the specifications of the battery and appropriate testing parameters should be carefully selected.
3. Testing process
① Observing data: During the testing period, carefully observe the data displayed by the instrument to ensure the accuracy of the test. If a fault occurs, the fault indicator light will light up and the LCD screen will display the fault information.
② Avoid interference: During the testing process, avoid unnecessary touch or operation of the tester to avoid affecting the accuracy of the test results.
4. Maintenance after testing
① Power disconnection: After completing the test, disconnect the power supply in a timely manner and perform necessary cleaning and maintenance work on the tester to extend its service life.
② Storage and maintenance: The tester should be stored in a dry and ventilated place to avoid battery depletion and damage caused by prolonged disuse. It is recommended to charge the instrument every 3 months (after turning on, the displayed battery level should be around 90%).
5. Other precautions
① Follow the instructions: Before use, carefully read the instructions, operate according to the correct method, and keep the instructions properly for reference.
② Safe operation: During the testing process, do not arbitrarily change or adjust the internal structure of the tester to avoid affecting the normal operation of the instrument. Meanwhile, avoid touching the internal components of the machine during testing to prevent electric shock.
③ Troubleshooting: In case of any abnormal situation, please immediately disconnect the power supply (by unplugging the power plug) to stop the test urgently.
Following the above precautions can ensure the correct use of the battery load tester, improve the accuracy and safety of testing.
The ZC-420A battery load tester is specifically designed for conducting verification discharge experiments, capacity testing, daily maintenance of battery packs, engineering acceptance, and testing of the carrying capacity of other DC power sources for battery packs. Using wireless communication technology, the discharge process of the battery can be monitored in real-time through PC monitoring software, monitoring the discharge process of each battery cell. The power consumption part of the instrument adopts a new type of alloy resistor as the discharge load, which is safe, reliable, pollution-free, stable and high. The whole machine is controlled by a 32-bit ARM microprocessor, with a 5.7-inch LCD touch display and multiple interfaces for users to choose according to their needs. The appearance design is novel, with small size, light weight, and easy mobility. After setting various discharge parameters, the entire discharge process is automatically completed.
