Calibration labels on instruments:http://hphsite.de/Vortex/Labels.jpg
One shows: 30.06.2011 (Next calibration 30.06.2012)
Other shows: 3.07.07 (No next calibration)
As a Product/Quality Assurance employee I've been dealing in the past
with calibrated equipment used for testing and verification of air space
equipment built for NASA, ESA, Roskosmos, JAXA, Boeing, Astrium and EADS
and in my book the second one is NOT OK at all, why no recent
calibration date and next date?
The above customers would NEVER accept a test and verification report in
which such measuring device was used for testing and verification!
This is what often happens with measuring equipment that cannot be
calibrated anymore and may in this condition NOT be used anymore for
testing and verifications purposes.
I really hope for you, you don't use this UNcalibrated measuring device
for your real customers.
Kind regards,
