Hi Peter, I am by no means an expert on this subject but I believe they use a tuning fork to calibrate the standard radar guns (the ones based on Doppler shift) so you may have asked to see the cal cert for the tuning fork. I think the police usually calibrate there standard guns daily and if she did not even know what you were talking about when you mentioned the cal cert she may not even know what it means to calibrate something so you may be able to make a case on that.
If you were pinched with one of the laser radar guns you may be into a tighter spot and I have no idea how often or even how they calibrate those nasty guns. Good luck, and don't crack under the pressure when the judge is glaring at you! :-) Jeff Bailey Compliance Engineering SST - A Division of Woodhead Canada Phone: (519) 725 5136 ext. 363 Fax: (519) 725 1515 Email: jbai...@sstech.on.ca Web: www.sstech.on.ca All comments contained in the message are my own and do not necessarily express the views of SST/Woodhead Canada Limited. -----Original Message----- From: Peter Merguerian [mailto:pmerguer...@itl.co.il] Sent: Thursday, November 16, 2000 9:28 AM To: emc-p...@majordomo.ieee.org Subject: Speed Measuring Devices Dear All, Yes, I did get a speeding ticket today! I am not sure if I was speeding or not - I do not have my eyes on the speedometer all the time! I asked the policewoman to show me the calibration certificate on her speed measuring gun. She did not know what I was talking about! I inspected the gun and did not see any stickers on it. I plan to go to court and attempt to convince the judge that the speeding gun was not calibrated and/or the gun's measurement data may have been affected by emissions from another device. Can anyone in the calibration business send me professional opinions on the methods and reasons for calibrating speeding guns? What is the best way to present this case in court?
