The ChronoMaster is a precision measuring device for meas-
uring the rate deviation, the amplitude and the beat error of
mechanical watches. The compact microphone has integrated
measurement electronics.
All common beat numbers can be determined automatically.
The manual adjustment for any beat numbers in a range
between 3’600 and 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 anchor escapement
•Cylinder escapement
•Duplex escapement
•Chronometer escapement
•Co-Axial escapement
•AP escapement
Information on the measuring options
Further information on the measuring options is
to be found under
Ä
“Measuring modes”
on page 8 and in the corresponding software
manual.
Measuring options
01.09.2020Precision measuring device ChronoMaster6

Two ChronoMaster software versions are available:
•ChronoMaster
•ChronoMaster PRO
The “Witschi Token Installer” software can be used to install a
token on the device to extend the device to the PRO version.
Ordering the token
The token is created exactly for the device to be
extended. The token contains the item number
and the serial number of the device.
For further information, see the software
manual.
Using what is called a demo token, you can test the PRO ver-
sion for a certain time. The demo token has a timestamp and
can only be installed once on the device. If new functions are
provided by the manufacturer, a new demo token can be cre-
ated, which can be installed again once.
A USB cable is used to connect the ChronoMaster to the PC or
tablet computer. The measurements are controlled using the
corresponding “Chronoscope Service” display software.
In the “Chronoscope Service” display software, you can
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 for the ChronoMaster PRO version.
Information on controlling the measurements
Further information on controlling the measure-
ments is to be found under
