Positioning is set, and electrically susceptible protection equipment of different shapes is directed to when test, only need to unscrew fixed screw, measuring device can be in walking trough
Middle progress position is mobile；
It is furnished with graduated scale in the scale framework, graduated scale length is 50cm, and precision 0.1mm is used to indicate test
The mobile distance of prism；
Position of the hand screw for prism pallet is mobile, can guarantee test prism kept in moving process
It is steady and accurate；The clamping screw is used for the fixation of hand screw shift position, when being tried in measurement process
It can guarantee that current test position does not shift when testing interruption；
The prism pallet is furnished with tuning drive gear, prism holder and moving track, and prism pallet is by M6 screw and manually
Screw rod is connected, and tuning drive gear is directed toward scale framework, and prism holder is used to test the position of prism for installing test prism, moving track
Set movement.It, can be according to wheelbase size rotation manual screw rod, according to scale after determining the grating wheelbase of electrically susceptible protection equipment
Pointer indicates that guarantee prism centers are directed at beam center to move the travel distance of prism pallet.
