Pulsar Timing Trimmer

[Planet-LED]

Does anyone know how many total seconds of adjustment is present in the gross trimmer of a P2/P3 module?

On a two-trimmer module, a span of + or - 30sec/month [or a total range of 60sec/month]. On the fine-adjust, 1 turn = 1sec/week [total range of + or - 9sec/week, or 36 sec/month]. The early P2 modules with the large circuit boards and horizontal light sensor have only the fine trimmer on the back and so have a much reduced adjustment range.
