Re: Timegrapher machine
"sellwatch"
Looks like there is a high end and low end one. From what i heard, the low end one gives a different reading each time.
Guess im gonna pass on hooting one.
the real mccoy cost well into 4 digits....
the china mades wans , anything from 280usd i think.....
k2's has some funny readback within the same watch it can go from -ve to +ve seconds (slower to faster)
mechanically, its quite not possible, if a watch is fast, it should always beat faster, same for slower watches, considering the watch is dead fixed on the machine stand.
There's another port for "calibration frequency" , this i believe, is the part that makes the real thing apart from the replicas.
The actual company making this device or any good standard lab should be able to use this port to calibrate and fine tune the accuracy of this machine itself from time to time, esp for companies that bought it, needing to achieve ISO standards, such calibration also easily cost 3 digits per tune/calibration.
