5DISPLAY MODES
5.1 Display Mode Diagram
Measured values for rate deviation and
beat error are continuously displayed during
the measurement process. The slope of the
diagram can be changed (1, 2, 4, 8 and 16
times) by pressing the plus and minus
buttons (zoom).
Measured values for rate deviation, ampli-
tude and beat error are displayed numeri-
cally. The last measured result remains
displayed when measurements are paused.
The last eight pages are shown as small
format strips under the current diagram if
measurements have been performed for a
long enough time. If measurements are paused, one of the last pages can be selected with the left
and right buttons. The desired page can also be displayed in a large format by directly touching it.
5.2 Trace Display Mode
This display mode is combined with the
Vario display mode. It is possible to switch
between the two modes during
measurement or during a pause.
The rate deviation and the amplitude are
contiguously recorded. The plus and minus
buttons allow zooming in and out (1 to 8
times).
Measured values for rate deviation, ampli-
tude and beat error are displayed numeri-
cally. The last measured result remains
displayed when measurements are paused.
The means are numerically displayed at the
end of the measurement time.

Witschi Electronic Ltd Chronoscope X1 (G3) Page 15/39
5.3 Vario Display Mode
The Vario display mode measures the rate
and amplitude stability over a longer time
range.
The following measured values related to
rate and amplitude is continuously up-dated
during the measurement process: smallest
and largest measured values, mean,
standard deviation, elapsed measurement
time and current measured value.
Measured values for rate deviation, ampli-
tude and beat error are displayed numeri-
cally. The last measured result remains
displayed when measurements are paused.
The means are numerically displayed at the end of the measurement time.
Checking the rate quality:
The evaluation of the quality takes place via the interpretation of the 2 analysed rate values.
-The difference between the minimum and the maximum rate value, presented with the
vertical arrows, is a quality indicator of the watches condition. The smaller the difference the
better is the rate stability.
-The average value X is an indicator for the adjustment quality of the watch movement.
-σ(Sigma) shows the standard deviation ( 68.2%) of all instantaneous rate and amplitude
measurements. (1 Sigma = +/- 34.1% = 68.2%)
5.4 Sequence Display Mode
A measurement cycle including up to 10 test
positions can be defined in this mode. The
measurement cycle can also be started from
Micromat C.
The left and right buttons allow selecting
one of the Diagram, Trace, Vario and
Sequence formats during or after the
measurement cycle.
The following measurement results are
calculated for rate, amplitude and beat
error:
-Mean for each test position
-X: Mean of all test positions
-D: Difference between the largest and the smallest measured value.
-DVH: Only for rate and amplitude. Difference between the mean of all vertical test positions
and the mean of all horizontal test positions.
-Di: Only for rate. Difference between the 6H and CH test positions.

Page 16/39 Chronoscope X1 (G3) Witschi Electronic Ltd
-DVm:
Standardized rate difference proportionally to the size of the unbalance. I.e. theoretical
maximum rate difference causes by the unbalance of the balance wheel, at an amplitude of
270°, in the two vertical positions where the unbalance is down or above on the vertical.
-Φ:
Watch is in vertical position. Shows the place of the unbalanced point on the balance wheel
(flash)
I.e. The rotation angle of the stem refers to the 3H position.

Witschi Electronic Ltd Chronoscope X1 (G3) Page 17/39
During the course of a measurement cycle,
the test position and measured rate accuracy
will be displayed.
After an elapsed measurement cycle appears
in “Diagram” display mode the test positions
with its numerical measuring values of rate
accuracy, beat error and amplitude.
5.5 Polar Display Mode
POLAR display mode indicates the rate stability in a polar diagram. One revolution (rotation time) of the
Tourbillon watch corresponds to one revolution on the diagram. The average values of rate, beat error
and amplitude for specific angles are calculated and displayed. The watchmaker can now determine the
centre of gravity of the balance wheel.
First, the desired start position (9H, 6H, 3H or
12H) must be selected. By pressing the
 start button on the MMC the start position
6H is automatically approached.
Upon reaching the start position, the
stabilisation time must be awaited before
starting the measuring cycle (i.e. 30 seconds
stabilisation at a rotation time of 60
seconds= half turn of the Tourbillon cage).
Then start the cycle with:
- start button on the MMC or
- button on the X1

Page 18/39 Chronoscope X1 (G3) Witschi Electronic Ltd
Important!
The measurement time should be at least the
tourbillon rotation time. Recommended is a
measurement time that corresponds to five
full tourbillon rotations (see chapter 6.5vv,
page 26).
The first result is automatically assigned to
the value P000. Thus, the measurement can
be repeated again and again, the user must
define a starting point based on the visible
balance wheel and the trigger the
measurement always in same condition (Fig.).
With the two arrow buttons you can toggle
between the displays of rate accuracy and amplitude.
Results:
-P000: Average value of the results at the star of the measurement
-P090: Average value of the results after a 90° rotation of the tourbillon cage
-P180: Average value of the results after a 180° rotation of the tourbillon cage
-P270: Average value of the results after a 270° rotation of the tourbillon cage
-Xv: Average value of the four results P000, P090, P180 and P270
-Xp: Average value of all results of the total measurement time

Witschi Electronic Ltd Chronoscope X1 (G3) Page 19/39
5.6 Scope Display Mode
Mode: Scope 1
The acoustic beat noise of the watch is
graphically shown in this mode. A tick and
a tock are always alternatively shown.
A time range of 20 ms, 200 ms or 400 ms
can be selected with the left and right
buttons.
The last eight beat noises are shown as
small format strips under the current beat
noise if measurements have been
performed for a long enough time. The
desired beat noise can also be displayed in
a large format by directly touching it.
Mode: Scope 2
In this mode the averaging can be
switched on and off with the button. The
time range is fixed at 20 ms. Presentation
of the beat noises (tic and tac) on two
horizontal axes.
When the averaging mode is turned off,
the beat noises are continuously recorded.
When the averaging mode is turned on,
the graphical presentation of a certain
amount of beat noises is averaged.
Picture 3 Picture 5
The duration of the measurement cycle is determined by the beat number and the selected interval.
He is finished after 50 Tic and 50 Tac intervals. Then the average value of the amplitude is displayed
on each horizontal axe. It cannot be said on which horizontal axe the Tic or the Tac is assigned.
When you click on Picture 3 the average value after 10 intervals is displayed, and for Picture 5 after
20 intervals.
The Averaging of the signal is a process, by which the noise can be reduced in repetitive signals. By
additive superposition the signal is thereby increased, while the superposition of random noise leads
to no gain. Overall, the signal-to-noise ratio is improved.
