1. Introduction
1.1. General information on the device function
The Chronoskop CHR-9 timegrapher is an electronic measuring and testing device for the
production, repair and service of mechanical watches. The Timegrapher allows as well an
acoustic as a light barrier measurement with an external light barrier. Values such as Rate,
Beat Number, Beat Error and the average duration of a half-wave can be determined. With
sufficient quality of the acoustic signal, the amplitude of the clock can be measured. In a
long-term measurement, the temporal behavior of the rate can be observed on a graph. The
measurement results are displayed as graphically and as numerical values on the illuminated
touch display. During the measurement, you can switch between different display modes.
The target rate can be determined automatically, selected manually or individually set and
saved.
The acoustic measurement is realized with the built-in or an external piezo microphone. To
decouple acoustic noise, the built-in piezo is mounted on a 5 mm thick foam. The signal gain
can be adjusted with the rotary knob in the front wall. To measure a watch or a small clock, it
is to be placed on the piezo disk of the built-in microphone.

The optical measurement with the light barrier is used to measure pendulum clocks.
The multilingual menu navigation in English, German, Spanish, French, Italian and Polish
guides you easily and clearly through the functions.
The Timegrapher can be calibrated with an optional DCF77 radio receiver. The radio signal
of the atomic clock in Mainflingen (DCF77) is used as a reference signal for calibration. This
calibration method allows a measurement accuracy of a few seconds per year. In order to
ensure the highest stability of the quartz frequency and thus also the measuring accuracy,
the built-in quartz oscillator is heated in a quartz oven and kept at a constant temperature.
Thanks to the built-in headphone jack, you can directly listen to the clock work. The device
also has an external microphone input, an interface for external sensors and active
microphones, a microphone sensitivity control, a contrast adjustment knob and a touchpen
slot.
The measurement results can be sent via a USB interface to a PC, where they can be saved
or printed with the software Chronoport 2.0. All data is constantly sent to the computer and
displayed there as numerical values and graphics. Direct data transmission allows the entire
measurement to be displayed in a movable endless graphic. You can switch the operating
language between the languages English, German and Polish. The measured data are
stored together with the graphic. An summary of the measurement is printed on a DIN A4
sheet. The software can be installed on the computer, but can also be started from the disk.
System requirements: MS Windows from version Windows 98. The software is available as
download on our website. Of course the device works also without a PC.
The use of the latest microcontroller electronics realized with modern SMD technology allows
a compact solution (about 9cm x 9cm x 4cm) that gives the device manageability, it is easy
to transport and can be used in battery mode in many places. For further actual information,
please refer to the user manual, which you can download from our website.

1.3. Touchdisplay
The device has a touch display. It should not be confused with greater force than the weight
of 100g: Fracture risk! To operate the timegrapher use the included touch pen. Do not use
sharp metal objects. You can also use your fingernail or a blunt tip of a plastic pen. Fields
with a given touch function in the moment, are always described on display with bright
lettering on a dark background.
1.1. Commissioning
For power supply use only the power supply included in the
package or our battery pack. Commissioning of the unit should
be considered in the ambient temperature in which the
instrument has been calibrated (see chapter "calibration"). The
timegrapher turns on by pullig the touch pen from the housing.
To turn it off insert the touch pen back into the housing.
1.2. Battery mode
The device is equipped with a battery case, which is located on the lower side of the device.
In battery mode, the Timegrapher is operated with a 9 V block. In order to increase the
battery life, the display illumination can be switched off in the settings. It may happen that
when the battery power drops, the display contrast must be readjusted when switching to
battery operation.

2. Theoretic basics
2.1. Beats / Rate / Period Time
To calculate the rate deviation (R), the measured period is compared with the set or
determined reference value. The period or half-cycle duration is the average time between
beats.
Period duration is calculated as follows: TP= ( TTIC + TTAC ) / 2
The number of beats per hour is called the Beat Number (BR).
2.2. Beat error
If the balance oscillates asymmetrically around the zero position, the period duration of
consecutive beats TTAC and TTIC is unequal. The beat error is calculated from the difference
between the half-wave durations and given in miliseconds.
Beat error is calculated as follows: TP= ( TTAC –TTIC ) / 2

2.3. Amplitude
The amplitude is the maximum amplitude of the balance and is given as an angle to the
equilibrium position. The amplitude values of the wristwatches are around 260 ° - 310 °.
To determine the amplitude, the impact sound must be examined more closely. A beating
noise of the Swiss lever escapement consists of three impulses:
1. Impuls: The lever of the roller hits the fork of the anchor.
2. Impuls: A tooth of the escape wheel hits the impulse surface of a pallet and the
anchor fork touches the lever stone.
3. Impuls: The strongest noise. A tooth of the escape wheel falls on the resting surface
of the pallet and the anchor rod strikes a limit pin.
Based on the known lift angle λ(mostly 50°- 52°) and the measured lifting time of the
balance TH(time interval between the first (1) and the third (3) impulse), the amplitude Ais
determined.
