I. Judging from the appearance, there is no deformed, protruding, leakage, broken blow, charred, screw connection, etc. Second, the load measurement If there is no abnormality in the appearance, the UPS operates in battery mode, with a certain amount of load, if the discharge time is shorter than normal discharge time, after charging 8 hours, it is not necessary to return to normal alternate times, determine the aging of the battery.

Third, the battery decomposition instrument is used to test the simple battery tester, and the battery voltage can only be measured in a large current discharge state, which is generally judged to the storage capacity of the battery. At present, more advanced battery testers can accurately measure cold start current (CCA), such as WDKR-J battery discharge monitor, in addition to start discharge. The judgment is as follows: 1.

When using the battery tester 10 to 15 seconds, the voltage is maintained at 10.5 to 11.6V, indicating sufficient capacity, battery is not faulty; 2, the voltage is kept at 9.

6V ~ 10.5V, indicating insufficient capacity However, the battery is not faulty; 3, the voltage drops below 9.6V, indicating that the capacity is less insufficient or the battery is faulty.

Product specific features: 1. Have internal resistance detection, capacity evaluation function on battery packs. 2, with the function of online monitoring of the battery pack multiple index properties: in the battery pack, in the line discharge, all charge, the battery pack and each cell battery can be monitored online, the monitoring content includes: Battery whole set of voltage, each unit battery voltage, battery pack charging current, battery pack monitoring time, battery pack charging capacity and other indicators.

3. Function with fast and accurate identification of battery strength. It has the function of checking the discharge experiment on the battery pack according to various discharge rates, accurately known the true capacity of the battery; online compensation discharge function, realization dynamic compensation in all the processes of the discharge, to ensure the real constant current discharge of the battery pack.

4, using the device online discharge process, the voltage of each single battery is monitored in real time; 5, the entire set of voltage is 24V / 48V / 110V / 220V / 380V, the monomer voltage is 2V, 6V, and 12V battery packs for detection , Users can choose to set the monomer voltage type. Monomer volta fanaraha-maso Module, tariby Wireless azo atao. 6.

Four discharge termination conditions can be set at the same time when doing capacity discharge experiments: 1 Termination of the entire set of voltage; 2 single voltage stop conditions; 3 discharge time termination conditions; 4 discharge capacity termination conditions. It can also be based on the active detection process to terminate; 7,7-inch color touch screen. 8, easy to operate: all modular interfaces, good human-machine dialogue, simple operation, clear process, every interface and operation steps have simple tips, fundamentally alert error operation.

9, the instrument can perform histogram and curve decomposition and curve comparison function on tight detection results. Convergence the voltage curve can continue to be enlarged, narrowed, easy to observe. No need to upload the PC can clearly decompose data.

10, discharge parameter template function, straight call preset parameters can be discharged. Intelligent discrimination procedure, can intelligently judge that the monomer is not falling off, and if the monomer is falling off, it will not interrupt the detection. Input overvoltage protection, LCD prompt, buzzer alarm; overcurrent protection, LCD prompt, buzzer alarm; battery voltage polarity reverse protection, LCD prompt, buzzer alarm; 11, complete communication function, RS232 Communication Interface and SD card interface.

The data is incompatched into the computer, performing the library management, can make long-term historical data saving and decomposition; use SD card delivery data, detect at any time to save, light, safe and reliable. 12. The probe main machine uses the monitoring part and the power part integrated design, and the power part uses new high-function devices.

13. Adopt a new special low-efficiency load material and advanced control technology to ensure higher constant current accuracy. 14, the instrument has a parallel function, which can also be loaded, so that the instrument can detect a variety of large-capacity batteries.

15. Powerful PC software decomposition function: supply data management, printing, decomposition, report statistics, automatic generation of probe reports, reporting features. Convergence the voltage curve can continue to be enlarged, narrowed, easy to observe.

Quick Find History. 16, with automatic detection protection function: When testing the entire group or monomer battery is tested, the detection is automatically terminated, and the alert has caused the battery, and complete alert to the equipment; can also be terminated according to people Informed detection process. 17.

After the detection is completed, all calculation results are automatically displayed, and the maintenance proposal is supplied according to detailed data. 18, storage mode: internal storage or external storage can be selected. Internal storage minimum interval 1 minute.

External storage minimum 5 seconds. .
