Product Features
- Signal source: built-in sine wave generator and sweep controller, dual SD card signal output, can be two groups to do different signal aging tests
- Two groups of voltage can be arbitrarily set 20-way simultaneous monitoring, automatic recording and display of voltage/current/DCR/temperature rise/test time and status
- Automatic calibration of test voltage, accuracy up to ≤2%, display 0.001V
- Panel 7 inch LCD, display content is richer, larger font, easy to observe
- Temperature rise measurement range: 0 - 200 ° C, measurement accuracy ≤ 5% ± 1 ° C
- Support a variety of operating modes normal intermittent debugging, including a small intermittent support 0.5S, and still be able to accurately measure the voltage
