![]() Tuning forks are also responsible for police radar guns. Stamped with KSI, frequency band, speed, units of measure, and unique serial number. In medicine, the Rinne Test is a common method used by Audiologists to test for hearing loss. The RADAR clearly displays the measured fork values and calculated results greatly reducing the time an officer may spend each day conducting fork tests without losing the accuracy or confidence of a traditional fork test,” says Kent Hayes, Kustom Signals Speed Product Manager. Two-piece, Directional Moving / Stationary, Doppler RADAR system. The operator simply rings the low and high fork once for each antenna. Continue to measure the radar speed and decrease. ![]() ![]() “The Advanced Tuning Fork Test eliminates the need to perform multiple separate fork tests for stationary and moving operations with a one or two antenna RADAR system. radar device tuning fork test (5.5) and measure the radar speed generated by the tuning fork frequency. Additionally, the feature provides an agency with the option to require a successful periodic fork test be conducted before the RADAR can be placed into service. Single Tuning Fork 24.00 Select options Pair of Tuning Forks 48. The speed of any motor vehicle may be determined by the use of (i) a laser speed determination device, (ii) radar, (iii) a microcomputer device that is physically connected to an odometer cable and both measures and records distance traveled and elapsed time to determine the. The feature takes the guess work out of the test process with the results clearly indicated on the front panel display. 46.2-882.Determining speed with various devices certificate as to accuracy of device arrest without warrant. The Advanced Fork Test Feature guides the operator through the tuning fork test process and greatly improves the ease, speed and accuracy of the tuning fork test. The tuning fork test is used by law enforcement to confirm the accuracy of the RADAR used when tracking the speed of vehicles on the roadway. The feature has now received patents in the domestic US as well as Canada and an Innovation Patent Certificate in Australia. It all depends on what the department buys and or what the radar manufactures sell to the department.Lenexa, KS, Aug– Kustom Signals, Inc., announces multi-country approval of the patent for the Advanced Tuning Fork feature included with the new Eagle 3 and Raptor RP-1 traffic RADAR systems. Some departments require the tuning fork test before using the radar for. There are several ranges of tuning forks that can be used. Strike lowest speed tuning fork and place in front of active antenna. But from personally seeing other officers do it, I know it happens. Your suppose to use a hard surface, but not the other fork because it could change your readings or damage the forks. We were taught not to strike the tuning forks on one another to do our accuracy check either. The resulting digital rea.of the police car and secured a reading compatible with the test results obtained by testing the unit with the tuning fork. However, some states may require testing and calibration less frequently. Device manufacturers devices recommend calibration before every use. As was told to me several times we don't calibrate the radars the manufacture comes out once a year and does that. Radar guns, for example, require the use of a tuning fork to ensure the device is producing accurate readings. I introduced calibration certification for both the radar and tuning forks into evidence. If one of the three are not working, or the forks are off by more than a mile you shouldn't be using the radar unit. I cross examined the police officer for about 25 minutes. Always remember the forks along with the other test, Audible Tone, and lights are to CHECK the accuracy of the calibration of the unit. A lot of officers do it after every stop that they cite someone on. Most places around here your taught to do it at least at the start and end of your shift. The fork is tuned to vibrate at a frequency equal to the doppler frequency for some set speed, usually. The radar check fork is specially calibrated for checking a radar unit. The special tuning fork is not to be confused with the forks used to tune musical instruments. (We're also not allowed to use the "fastest target" window. A special tuning fork can be used to check the calibration of traffic radar. My radar instructor said that the Michigan Speed Measurement Task Force doesn't allow it. For some reason, we don't do the "tuning-fork test" in Michigan.
