Page 13: Rate Measurement Of Quartz Watches
The Analyzer Q1 is equipped with a single transducer for acoustic, capacitive and magnetic signal acquisition. It allows checking watches with closed wristlet, open watches and movements. If the watch is supplied from the Analyzer Q1, its rate deviation is derived from the supply current (see chapter 9.2). -
Page 14: Result Display
If the signal is no longer available, the indication appears and the instrument jumps to the main menu after a while. Caution! If a watch is supplied from the Analyzer Q1, it is not possible to test another watch with the sensor. 6.3 Result Display Numeric mode, the current results are displayed in numerical and graphical analogue form. -
