Main Technical Parameters

1. 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: 1ms ~ 10000ms, resolution: 0.01ms,

External trigger test range: 1ms ~ 10000ms,

Resolution within 999ms: 0.01ms,1000-9999ms: 0.1ms, and over 10000ms: 1ms.

Accuracy within 200ms: 0.05%± 0.1ms

2. velocity measurement : instant separating (instant closing) velocity

Appointed time slot( stroke segment or angle segment) average

velocity
