Wuhan UHV-408 Circuit Breaker Analyzer

Time measurement

12 natural switching (closing) time

The opening (closing) phase is not at the same time

The difference between different periods of switching (closing)

Closing (opening) Bouncing time (number of bounces)

Internal trigger test range: 1 ms ~ 10000 ms, resolution: 0.01 ms

External trigger test range: 1 ms ~ 10000 ms

Resolution within 999 ms: 0.01 ms, 1000–9999 ms: 0.1 ms, over 10000 ms: 1 ms

Accuracy within 200 ms: 0.05% ± 0.1 ms
