If the beat error is high, the two 'tracks' will be further apart and even further as the error is increased. If the beat error is satisfactory, the 'track' will usually appear as one 'track' or two very close together. 0.6ms or under is very good for any watch. The Timegrapher displays the movements bph automatically, yet can be manually set. The lift angle is directly related to the amplitude readings. These lists mostly deal with Swiss movements. By the way, there are a couple of lift angle lists floating around on the internet. The lift angle default is 52 degrees, but can be manually set for your particular watch. The parameter display switches back and forth from the bph to the lift angle. The Timegrapher displays the +-sec/day, amplitude, beat error and beats per hour. If the 'track' is angled up, the watch is running fast, angled down, the watch is running slow, straight across and it is perfect for that position.

These manuals have examples of vibrograms with explanations as to the problematic conditions of the watch.

You can easily find and download the Vibrograf operation manuals in pdf format. The horizontal 'tracks' across the LCD screen dictate the same vibrograms of the old B100 and B200 Vibrograf paper tape machines. The timer compares the most prominent and important sounds of that full balance cycle with a quartz oscillator then displays the 'track' marks on the screen. There are ten noises in a full oscillation of the lever escapement. The Timegrapher is similar to the high-end instruments in that it analyzes the beat noise in the same way. Bought the Timegraher 1000 a few months ago.
