Problems solved by technology
[0003] At present, the on-line test devices for low-voltage equipment on the market have separate display screens for displaying voltage and current, which is not conducive to staff observation and statistical data, and has no storage function, requiring staff to take notes on the spot, which is prone to errors. It is easy to make mistakes, and the records are deviated. The existing devices all use knob-type adjustment keys, which are not easy to operate, and the range of adjustment values is not accurate enough, which affects the test results and low work efficiency.
