control

By means of a loudspeaker, which makes part of the standard
accessory, you can check the beat noise for irregularities and
side-noises.

An acoustic check is recommended when a clean diagram is
not formed with the normal amplification adjustment or when
the diagram shows irregularities which are not easily explicable.

Printout of the results

The following chapters can be used only if your instrument is
equipped with a printer.

13.1 Numerical

results

If the

print

key is pressed during a continuous measurement,

the results shown in this moment for rate, amplitude and beat
error will be printed out. In addition, the two header lines will be
printed out.

After each printout the paper is feed forward, so that the strip
can be tired off and attached to the watch.

13.2 Graphic

printout

If the key print

is pressed at the moment of a frozen display

(after pressing the key

start/stop

), the full actual display and

diagram will be printed out in a graphic form.

14 Operating

The following information is not necessary for operating the

watch-matic III

, but can help to understand the functioning of

the instrument and to interpret the displays correctly.

14.1

Beat noise of the watch

The beat noise of the watch is usually composed by three
different pulses:

•

The first noise results when the ellipse on the balance wheel
touches the fork (A). As to
time, this beat is very precise and is used for producing the
graph as well as for calculating
the rate and the beat error.

•

The contact of the escape wheel with the entry pallet
produces a second pulse (B). This noise is very irregular
and will not be used for the evaluation.
