Re: [Histonet] timer calibration

From:"Anthony Reilly"


I agree with Joe that histology timers do not need to be calibrated, but they are apparently in other scientific disciplines.

A simple and quick method which does not require any special equipment is to test your timers over a stipulated time frame against the time supplied service by your telephone provider.  The time is usually expressed in 10 second intervals.  If your  timer complied  over a one minute period it would be deemed satisfactory.

I'm sorry
am I the only one that thinks calibrating timers is stupid. I mean how many=20
histology procedures are so time sensitive that the timers have to be 
calibrated? Let's face it. I have had techs sit there and watch the clock=20
and rinse as soon as the timer goes off. And I've had techs wait for the 
timer to go off , then mosey over and rinse.  Both stains worked. I guess=20
I'm just not anal enough.
