YaeTek Watch Timing Machine Tester Tools Multifunction Timegrapher
<b>Feature:</b><br> - This watch testing machine automatically calculates rate, amplitude, and beat error using readings from the microphone stand. This stand allows you to position the watch 6 different ways to test reliability in different settings. <br> - The LCD screen shows the readings in real time with two dotted lines moving across the screen to provide a visual representation of the "tic tock" from your watch.<br><br> <b>Specification:</b><br> Sampling periods: 2, 4, 6, 8, 12, 20, 30 and 60 seconds<br> Rate Deviation Range: ±999 s/d with precision ± 1 s/d<br> Automatic beat settings: 12000, 14400, 18000, 19800, 21600, 25200, 28800, 36000, 43200<br><br> <b>Manual beat settings:</b><br> 3600, 6000, 7200, 7380, 7440, 7800, 9000, 9100, 10800, 11880, 12000, 12342, 1248, 12600, 13320, 13440, 13500, 14000, 14040, 14160, 14200, 14280, 14400, 14520, 14580, 14760, 14850, 15000, 15360, 15600, 16200, 16320, 16800, 17196, 17258, 17280, 17786, 17897, 18000, 18049, 18514, 19332, 19440, 19800, 20160, 20222, 20944, 21000, 21031, 21306, 21600, 25200, 28800, 32400, 36000, 43200<br><br> A good amplitude level is between 275 and 315.<br><br>
