General description
This chapter contains general information about the ONEOF® Accuracy Motion.
Introduction
The ONEOF® Accuracy Motion is an automated acoustic measuring instrument with backlash-
free positioning. It is designed to measure watches or mechanical movements in production,
laboratory or after-sales service.
One connector allow the device to be controlled by the software. The other one is an optionnal
power supply (iPhone/iPad only).
No other access to the components of the device is possible outside the technical services of
Petitpierre SA and H2i Sàrl.

The motor control, based on an inertial measurement unit, allows to reach any position of the
half-sphere with the required degree of accuracy. The device is supplied with a software
allowing the control of several devices in real time. The software is also equipped with a
sequence editor to automate the testing process. All data collected by the device can then be
stored locally or in a database.

A. Unhook a rubber band (1) from the bottom of the
Accuracy Motion.
The rubber band will be used to secure the watch
or movement to be measured on the Accuracy
Motion.
FIG. 5-1 - Holding rubber bands
location
The device can be used with a single power cable
(2) on a computer but requires a second power
cable (3) to be connected to a standard USB 5 V
charger (phone charger type) when used on an
iPhone or iPad with Lightning connector.
A 5 cm space around the base of the Accuracy
Motion must be left free to avoid any impact. FIG. 5-2 - Electrical connections
Installation
Installation and commissioning
The device has been checked, adjusted and tested in our workshops.
Application installation
A. Download and install the ONEOF® Accuracy2 App for Windows at https://h2i.ch/apps
System requirements :
• Windows 10 version 1803 or higher
• 64 bits
• Intel i5 processor or higher
• 4GB RAM or higher
The Accuracy Motion is also compatible with iOS and macOS.
Commissioning
B. Place the device on a flat surface before connecting it.
C. Connect the power cable (2).
D. The device goes to the initialization position
E. Wait 3 seconds during the calibration of the inertial measurement unit.
It is important not to touch the Accuracy Motion during this 3 seconds period.
The Accuracy Motion is closed-loop controlled and the measuring head cannot be
moved. It is not recommended to move the device once connected.
Installation 11|36

F. Open the cart and place the watch or piece to
measure.
G. Insert the holding rubber band into the lugs
provided (4) and (5).
The holding rubber band is used to secure the
watch or movement to be measured on the
Accuracy Motion.
It is very important to secure the object to be
measured with the holding rubber band provided
for this purpose. Petitpierre SA and H2i Sàrl cannot
be held responsible for any damage caused by a
falling piece or a watch during a measurement.
FIG. 5-3 - Position the rubber band
2 rubber bands are provided with the Accuracy Motion.
In case of loss or wear, contact Petitpierre SA to get new ones.
H. Start the application.
It is very important not to touch the device during a measurement or during a change of
position.

Description of the contextual menu tabs (5)
Accuracy
The Accuracy tab is dedicated to device overview and control. The Accuracy2 application
allows simultaneous control of multiple devices from the ONEOF® range. All connected devices
are displayed directly on the screen in the accuracy window. From there you can start
measurements, sequences and access all current data of your measurement.
[See Accuracy Tab, page 14]
Parameters
The Parameters contain the data about the watch you want to measure (frequency, lift angle,...)
but also how you want to measure it (how much integration time, stabilization,...). A
measurement cannot be made without parameters. There is always at least one set of built in
parameters called "default" that is used in situations where no parameters have been chosen.
[See Measurement parameters tab, page 23]
Criteria
The Criteria are used to control the way measures are displayed.

Performing a measurement
Simple measures
The control bar (see FIG. 6-3) allows you to make a simple measurement by selecting a
position.
The Simple measures control (3) button enables you to stop or restart the measurement.
Selecting a new position allows the measurement to be continued at the newly selected
position.
Sequence measurement
The Measurement sequence control button (2) is used to start or stop a sequence of
measurements.
A measurement cannot be performed without parameters. When a device is connected, a
set of default parameter, defined in the parameters tab, will be used. If no default
parameters are set in the parameters tab, the application will use the "built-in"
parameters instead. . You can view these parameters by clicking on the Device
parameters button (6) located in the Control bar (voir FIG. 6-3).
To view the Device parameters, remember to select the Device overview window.
Saving a measurement
The Measurement saving button (4) of the Control bar (see FIG. 6-3) enables you to save the
measurement that has just been made.

Results area
Device status
The Results area (7) displays the result of the measurement in real time. It includes the
beat error, the accuracy and the amplitude of the measured watch. Each of these values
is updated every second.
The Scope view is the graphic display of the ticking signal of the watch movement. Through the
bezel, expert watchmakers can detect problems with the escapement phase. It is also a very
useful tool to determine if the upcoming signal is good enough for a correct measurement of the
watch.
The Swiss lever escapement is composed of 3 distinct impulses. The first pulse is
temporally very accurate and is therefore used for the calculation of the rate accuracy
and the beat error. The second pulse is very irregular and cannot be used. The third
pulse, the most powerful, is used to estimate the amplitude of the balance wheel.

Every second, a new value of precision rate, amplitude and beat error is added to the graph. It
is always interesting to check how these two values vary over time. Some particular and natural
fluctuations may appear, such as the impact of gear train defects, the drop of the amplitude at
the time of change, or more generally the variation of the rate over the whole power reserve of
the watch. Each position is represented by a color.

As soon as the frequency is detected, the diagram starts to display the results. Each point
represents a tick or a tock in time, which is shown as two lines.
• If the watch tends to run faster, the slopes are positive.
• If the watch tends to slow down, the slopes are negative.
• If the watch is perfectly accurate, the graph displays flat lines.
If the watch has no beat error, the two lines are superimposed. If the beat error is greater than
0.0 ms, the lines are spaced. The greater the beat error, the greater the space between the
lines.
