3 way test ets?.....why

[collins and stevens]

Why and how do you 3 way test an ets clock? If the clock is set via the club system atomic clock there is never a variance as the time after the race on your ets is the time you record.

Rpra rule state that u have 2 run for 24 hours so we just doing a dummy race run! x(dizzy)

Once set at the club by the master the tipes does not energise again until plugged in for race....it has an atomic clock which is synchronised with the master and has no variance........is it a 3 way test(which checks for variance in time) or just a functionality check?......all seems futile as if an ets gained 10 seconds it would probably be thrown out.......unless their is a problem with greenichs atomic clock it has to be a dead clock once synchronised........doesn't it????

then why a three way test .ie .a normal clock is tested on three  sides . ETS is not .a variiation  of 48 hour diference

The original 3way test was designed for testing the balance wheel on the wind-up clocks. You had to test the balance wheel in the horizontal position, then in the vertical position on its right hand bearing and then once again in the vertical position on its left hand bearing.

This was necessary because, in the older clocks, the balance wheel could become worn and there could be a marked difference in variation depending which way the balance wheel was aligned. Unscrupulous fanciers could use this knowledge to gain vital seconds.

The 3way test was designed to check for any discrepancies.

The more modern quartz, having no balance wheel, needed only a one-way test for 24hrs.

Apart from running the clock, it should have always been checked for any physical security breaches, bit like an MOT.

As  for the ETS systems, I can see no real reason for tests, as it is all electronically secured and is self certifying. The only test you could put on an ETS system is a diagnostic test which could check the software within the clock,bit like an anti-virus program, perhaps this will come.

Good statements and clarifications in the last reply ..thx  .If you have to 3 way test the ets its like 3 way testing TIM as the atomic clock drives the systems

i was at a demonstration last monday and was told they can vary by the odd second which is why they are sync on marking and when docked for checking the corrected times are printed.

ETS can still vary over a 24 hour run  just the same as any quartz clock can T3s etc,I have had most of the ets clocks in our clubs vary by the odd second when we strike off after a race.

In the case of tipes/tauris once clocked and the ets taken to the club its plugged into the master, the tipes /tauris hand set displays the time on itself for printing , the unikon has the pocket clock(memory stick) plugged into the master and its info downloaded via the display on the master station. If there was a variance on the tipes/tauris you would see it on the clock but you couldn't see it on the unikon pocket clock.....in any case the master just prints the info. :-/

I have never seen a variance on any of these systems to date........maybe I'm missing something .....once synchronised with the atomic clock can the system vary?? Maybe someone who reads this knows technically how to clear this one up......I am but a humble fancier trying to do the right thing regards 3 way testing.... :-/

[collins and stevens]

you strike off ETS ??? I think the variance is in your manual clock strike .......you can strike off your manual clocks to the clock on your master ets as it is synchronised with TIM automatically.

YOu would see any variance on the members sheet that you print off after the race as it shows the setting and checking times,I havnt had any dealings with the Taurus or Types only Bricon or Unikon but I would imagine that they could still show a variance on a race.

anything electronic can have a variance as no power cell is able to give 100% constant power due to temp changes etc.

Its just one of the things you have to accept, no different to T3's etc, should they gain or lose the odd second? Same reason applies!
