3 Operation
The Ebatest allows the measurement of the shake on mounted watch-movements. Its accuracy is about one
micron. Its operating principle is as follows: when moving down the handle, the counter-tip (lower tip) moves up
and pushes the movement wheel from below so as to catch it in the slot. While continuing to descend the handle
the upper tip comes pressing on the wheel from above. By its own weight, the top pin will lower the wheel. A
feeler is measuring this displacement, which represents the clearance. The measure will be displayed on the
Micro Vision.

5 Use
To measure the shake of a wheel on a watch-movement, proceed as follows :
1. Connect the device (see chap. 4) and switch on the display.
2. Place the watch-movement you want to measure on the fitting.
3. Place the movement on the Ebatest. The mirror allows to easily set the correct fitting hole on the pin
(each hole corresponds to a wheel position on the movement and is specific to this movement).
