FAQs:
  • What is the main purpose of the Cartesykj Digital Tachometer Calibration Tool?
    It is a non-contact instrument used to measure the rotational speed (RPM) of components like rollers and shafts, primarily for calibrating vehicle speedometer testers to ensure accuracy and legal compliance.
  • How often should the speedometer tester be calibrated with this tool?
    It is recommended to perform formal calibration every 6 to 12 months, depending on the frequency of use, to maintain accuracy and meet regulatory requirements.
  • What are the key steps for calibrating a speedometer tester using this tool?
    The process involves preparing the tester and applying reflective tape, measuring RPM with the tachometer, converting RPM to vehicle speed using the roller diameter, and comparing results to adjust the tester if deviations exceed the allowed range.
  • Why is a third-party calibration certificate important for the tachometer?
    A valid third-party calibration certificate ensures the tachometer's accuracy is verified, which is necessary for legal metrology requirements and provides traceable evidence for audits or disputes.
