The ChronoMaster/ChronoMaster Air is a precision measuring
device that allows measurement of the rate deviation, the
amplitude and the beat error of mechanical watches. The
compact microphone features integrated measurement elec-
tronics.
All standard beat numbers can be determined automatically.
Manual adjustment for any beat numbers in a range from
3,600 to 72,000 A/h is possible as an alternative.
Watches can be tested in the 6 main testing positions, in 4 ver-
tical intermediate positions and in 2 special positions. The
position is identified automatically.
Using different measuring modes, watches can be tested with
the following escapements:
•Swiss lever escapement
•Cylinder escapement
•Duplex escapement
•Chronometer escapement
•Co-axial escapement
•AP escapement
Information on the measuring options
Further information on the measuring options
can be found under
Ä
“Measuring modes”
on page 9 and in the corresponding software
manual.
Two versions of the ChronoMaster software are available:
•ChronoMaster
•ChronoMaster PRO

The “Witschi Token Installer” software can be used to install
what is known as a token on the ChronoMaster to upgrade the
ChronoMaster to the PRO version.
Ordering a token
The token is created specifically for the Chrono-
Master to be upgraded. The token contains the
item number and the serial number of the Chro-
noMaster.
More information can be found in the software
manual.
Using what is known as a demo token, you can test the PRO
version for a limited time. The demo token features a time-
stamp, and can only be installed once on the ChronoMaster. If
new functions are provided by the manufacturer, a new demo
token can be created, which can be installed again once.
A USB cable is used to connect the device to the PC or tablet
computer. The measurements are controlled using the corre-
sponding “Chronoscope Service” display software.
The “Chronoscope Service” display software allows you to
choose between the “Diagram” and “Vario” display modes
for both versions. In addition, the “Trace” , “Sequence” ,
“Polar” , “Scope 1” and “Scope 2” display modes are
included with the ChronoMaster PRO version.
The ChronoMaster Air can either use a USB-C cable or a Blue-
tooth connection to communicate with the PC or tablet com-
puter.

ments is to be found under
