PULSE PARAMETERS
7.1
General Introduction
In the case of the rate measurement based on the magnetic or current stepping motor pulses, the
instrument also analyzes the motor pulses. This analysis provides valuable information on the
operation of the watch module. In particular, the present power level of watches with adaptive motor
pulses (Asservissement) can be determined without opening the watch (see chapter 16.5).
7.2
Result Display
The following pulse parameters are measured and displayed:
Motor period and display of the
End of Life
function.
Inhibition (see chapter 16.2)
Pulse Width
Drive Level (percentage of the chopping level, see chapter 16.5).
The chopping level is also graphically represented as a bar diagram.

LONG-TIME RECORDING (TRACE MODE)
When the
MODE
parameter is set to
Trace
, a long-time recording of the rate deviation and of the
chopping level is performed as a diagram.
Long-time recording includes changes in the rate deviation (e.g. caused by temperature variations)
as well as changes in the chopping level of watches with adaptive motor pulses (e.g. caused by a
change of date) for a duration reaching 60h.
8.1
Result Display
The upper part of the display contains the rate measurement diagram and the lower part the power
level of the chopping pulses.
