Detection

1, open and close valve voltage applied contrast test

1.1 conditions: perform on (or off) moves lowest energy (that is, the load voltage DC2 ~ 3 V), action in place, and then perform a reverse action to close (or open) the highest energy (that is, the load voltage DC4.2 V to 6 V) action in place.

1.2 Requirement: repeatedly in 5 ~ 10 times

1.3 Scope: all inspection

1.4 Instruments: homemade special testing table
