2 Parts of the machine
A wheel is positioned between the ruby Vs and set to revolve by a belt. The Wheeltest 1 comprises a series of
control knobs for the motor, and four screws to adjust the position of the Vs and of the drive.

3 Use
3.1 Start-up
The machine is started by the slide switch next to the power connection. When it is turned on, the motor will not
turn, but the last parameters used (speed and direction of rotation) will be restored.
3.2 Use
3.2.1Placing the component on the Wheeltest 1
The component to be measured must be placed between the two Vs of the Wheeltest.
3.2.2 Adjustments
1. Adjust the spacing of the two Vs by means of the micrometric buffer, in order for the wheel to be held in
the manner closest to its function once mounted in a watch.
2. The height adjustment of the V closest to the user is made by means of the black knob placed on the
right of the Wheeltest. The precise adjustment may be visualised by checking that the part displayed on
the screen is seen exclusively from above.

3. The wheel is now correctly placed, and must now be driven. The wheel should rotate at a maximum
speed of a one or two revolutions per second, or three teeth per second for slightly toothed wheels.
With buffer option:
The buffer allows the spindle of the wheel to be supported.
The buffer support pin is adjusted by means of the adjustment screw placed on the side of the buffer.
Drive adjustment is thus made by lowering the belt on a part of the wheel without visual measurement. The
position of the belt is adjustable, as to depth, by the screw placed at the back of the apparatus; it should be
placed on the spindle of the wheel or any other part of the wheel outside of the part to be measured. A height
buffer allows the bow to be positioned with a repeatable pressure.

Figure 2 : height buffer bow
Rotation speed is adjusted by the « + » and « - » buttons on the control panel; a lighted bar comprising 8 LEDs
allows the speed chosen to be visualised. Rotation is launched by pressing on the « on/ off » for 2 seconds; the
LED will turn on at the top of the button. Brief pressure on the « on/ off » button allows step-by-step rotations.
The wheel rotation direction is alternated by pressing the button at the far left.

5 Exclusion of responsibility/warranty
Damages caused by use, transportation or storage that do not comply with those described in this manual are
not taken care of by the manufacturer. Modifications to the machine and opening the casing are forbidden and
entail an exclusion of responsibility. The right to a warranty expires when these are demonstrated or if the faults
noted cannot be original. Consumables (belts) are not subject to warranty.
6 Maintenance and care
No special care is necessary for the Wheeltest 1, if it is used in a laboratory, except classic cleaning with a dry
cloth. The belt is a consumable to be replaced when the user deems necessary.
