Why do radar and laser before going out on all shifts need to be calibrated ?

Question

What causes the radar and lasers to go out of calibrasion?

Answer 1

nothing causes them to go out necessarily...but if you can't prove it has been calibrated when you give a speeding ticket then that ticket is not valid because your gun could be off...same as if you pace someone the easiest ticket to get out off because most cars aren't digital display so there is no exact speed of the pace and again if your speedometer hasn't been calibrated null and voids the ticket.

Answer 2

In order for the radar reading to be admissable in Court there must be a proper foundation laid for the evidence. Previous Court rulings have said that the foundation requires that the operator be certified in the use of the radar and the machine must appear to be operating correctly before and after it was used for the stop. Calibrating the unit shows that it is in proper working order.
The old fashioned units use tuning forks to calibrate the radars, but the newer units have built in calibration systems that only require the officer to press a button.

Answer 3

Quite frankly, it is really more the admissibility of the evidence. In for evidence to be admissible, you must show a proper foundation. If a defense attorney can create "reasonable doubt" by arguing that the radar device wasn't calibrated properly, it might cast doubt on the reliability of the readings. It might not be necessary to calibrate the machines on a regularly basis, but it looks better in court if they are checked regularly.

Answer 4

time.

time causes things to fall out of sync, it's that darn gravity and magnetic imperfections of nature, especially when your specifically precise measures are faulty.

when you sync something or calibrate it or precisely tune it, that means you have it set for perfection. think of it as guitar strings. Each time before a preformance...and sometimes even during...the preformer will tune the strings of his instrument for the best possible sound available. Its the same thing with precision instruments like lasers, otherwise you'll have an upload linking laser that is to tightly focussed and cuts like a laser...(heh no pun intended)...or a laser knife that is too thinly spread so it cuts like an upload link. Imagine that, microsurgery done with a butterknife. Eww, I don't think I would ever trust another surgeon again.

Answer 5

Because the very rare mistakes made by a non-calibrated device have been used in the past to challenge a ticket. Documenting calibration prevents this.

Answer 6

electronic malfuntioin, that is why they have to be checked prior to each shift by the officer. ( radar) I was not trained on laser, so I can't speak for it.

And as a note they don't go out that often.

Answer 7

properly it would fairly count on how i'm approximately to die. If i'm approximately to be murdered or if that is surprising i'd ask for 5 minutes to think of roughly my existence, the folk in my existence, and that i'd prey. If that is yet differently and that i've got a good volume of time i'd consult with the folk i admire and notice them one final time.

Answer 8

In order to better authenticate the evidence when at trial. Speeding tickets are often challenged and this strengthens the state's case.

Answer 9

its a check to make sure they are correct so that someone who is ticketed cant sue the department for false arrest and slander
