The requirement is to perform the manufacturer's recommended testing procedure. As models change and some become obsolete, so does the testing procedure.
The CBC article makes the claim, that there were no "new models" that made the tuning fork test obsolete.
The exact same RADAR devices are being used in the United States where law enforcement are doing the "tuning fork test".
The only difference is that the OPP asked Decatur to remove the test, because their officers were not doing them; and some were lying under oath, that they actually did it. ^this is straight from the CBC article.
John McNall, a former OPP speed-management co-ordinator, said he asked U.S. radar manufacturer Decatur Electronics to take the test out of its operating manuals in 2004. He cited concerns officers were "fudging their evidence" by testifying under oath that they had correctly used tuning forks when, in fact, they often didn't do the test, misunderstood it, or couldn't find the forks, he said.
"The officer would give evidence that he tested it in accordance with manufacturer's instructions and technically would be perjuring himself," McNall told CBC News.
Decatur could care less, they will remove whatever test is necessary in order to make a sale. If OPP asked them to remove all the tests in exchange for an annual internal circuit check. They will do it.
There are many RADAR manufacturers that the OPP can purchase from; which ever one does what they're told... gets the business.
