How can you test waveforms for steady-state testing ups battery? Generally in the no-load and full-load conditions, the observed waveform is normal, with the distortion meter to measure the output voltage waveform distortion. Under normal operating conditions, the maintenance-free batteries ups 44ah, load resistor, with distortion meter to measure the output voltage waveform total harmonic relative content of the product shall comply with the requirements specified in the import ups battery 44ah, generally less than 5%. Above content provided by Hebei Tianyi Electric Co., Ltd., we hope to help a friend in the same industry. UPS battery should be how to maintain it? UPS batteries are typically sealed maintenance-free batteries, users are recommended three to six months to do a discharge test, ups battery 44ah, and observe the battery capacity indicator changes in order to understand the current battery status. Other battery maintenance detection method is as follows: 1. visual inspection of the battery exterior if there is deformation or swelling leakage phenomenon. 2. View the battery + and - poles oxide 3 detects whether the battery terminals are loose 4. Charging the battery terminal voltage measurement?. (Each cell is normal for 13.7 ~ 13.8Vdc) 5. UPS battery life longer, regular maintenance should be more intensive, prevent the mains power supply interruption UPS can not be delayed. 6. It is recommended for use at ambient temperatures between 0 ℃ ~ 40 ℃, supply ups battery 44ah, avoid direct sunlight and keep the clean air. 7. The personnel responsible for implementation of the recommendations battery maintenance Battery maintenance under the guidance of a professional engineer or ask a professional engineer to perform, to avoid electric shock happens.
