supply voltage (car or internal battery)Ī police or sports Doppler microwave radar will register a speed from a vibrating tuning fork's narrow side, the higher the tone the higher the speed.Tests / Automatic Adjustments may include Self-test only checks and adjusts a portion of the electronics, the radar should also be checked with calibrated tuning forks before use. The degree a radar self-test and automatically adjust circuits varies with model and ranges from none or little to testing 50 percent or more of the electronics. Long range, most sensitive, may make the radar susceptible to local interference. The Range Control is actually the receiver sensitivity setting. Set radar to Receive Only mode and scan for interference at operation site. Best to run test at operational location. Test vehicle should have a calibrated speedometer for a valid test. Test Radar against Vehicle of Known Speed.Two (2) tuning forks with different resonances required to test moving modes. Check Radar with Calibrated Tuning Fork(s).A sticker on the radar, or records, should indicate last calibration test, next (due) test, and who tested. Most states require a radar be tested by a certified shop periodically, typically once or twice a year. To insure radar hardware is setup and functioning properly the operator should perform several actions. Next Speed Radar Test and Calibration Contents.
