Horotec FLASHTEST - Unjamming Wheel Trains (Turbo); Measuring Rate Stability (Accuracy)

11
E. Unjamming the wheel trains
It is possible that a watch does not restart immediately after a battery change or a prolonged stoppage.
It is then necessary to generate a powerful magnetic field to test or unjam the wheel train.
If during this action the hands do not make a fast rotation, it means that a wheel (or wheels) is broken or that the wheel train is too dirty.
E1. Press the
TURBO
key on the main menu
FLASHTEST
to unjam the wheel trains.
The following screen displays :
F. Measuring the stability of the rate (gain/loss) of a watch or movement
The tester for analogue quartz watches receives magnetic signals from the motor of the watch. The device measures the stability of the rate of the watch and
calculates an average by a specific method from the received impulses (the average is given in sec/month).
F1. Press the
ACCURACY
key on the main menu
FLASHTEST
to measure the stability of the rate.
The following screen displays :
Place the watch on the blue velvet plate.
Press the key and check if the hands have a fast rotation. Press to the test.
Note 1 : when operating on battery, reduce the test duration to preserve the capacity of the device battery.
Note 2 : it is sometimes necessary to move or turn the watch on the sensor plate to find the ideal position.
Place the watch on the blue velvet plate.
The generation time of signals (1, 2, 5, 10, 20, 30 or 60) will appear on the screen after a few seconds (sec/pulse). (1)
In the middle of the screen the number of required impulses at the beginning of the analysis (60/generation time of signals) will be displayed. The software starts
a countdown by pulsations. Once the countdown is finished, the rate accuracy of the watch will be displayed on the screen (in sec/month, for example : -1.75 sec/
month). (2)
There are 5 signal levels. The more bars displayed (1 bar = low, 3 bars = medium, 5 bars = optimal), the more the measurement precision. (3)
If a watch is detected when the main menu
FLASHTEST
is displayed or the device is in sleep mode, the screen will automatically switch to the submenu
