Overview
12.04.2018 Precision measuring device ChronoMaster 5

The ChronoMaster is a precision measuring device for measuring
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 vertical
intermediate positions and in 2 special positions. The position is
identified automatically.
Using different measuring modes, watches can be tested with the
following escapements:
nSwiss anchor escapement
nCylinder escapement
nDuplex escapement
nChronometer escapement
nCo-Axial escapement
nAP 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.
Two ChronoMaster software versions are available:
nChronoMaster
nChronoMaster 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 version
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 created, which can be
installed again once.
