RKI Instruments support FAQ

Common questions about manuals, registration, and support for this brand.

  • How do I perform a bump test on my RKI gas monitor?

    A bump test involves exposing the monitor to a known concentration of target gas to verify sensor response and alarm functionality. For many models like the GX-Force, this can be done in User Mode or by applying gas in Measuring Mode. Refer to your specific model's manual for the exact procedure.

  • What indicates a successful calibration?

    During calibration (or gas adjustment), LED indicators typically light up green for a pass and red for a failure. The LCD screen will also display a pass (P) or fail (F) status. If calibration fails, the device may shut off automatically or require sensor replacement.

  • How often should I calibrate my RKI instrument?

    Calibration frequency depends on the specific device and usage conditions. Generally, RKI recommends bumping the instrument before each day's use and calibrating if the bump test fails or at intervals between 3 to 6 months for typical applications.

  • Where can I register my RKI Instruments product?

    You can register your new gas detector online at the official RKI Instruments registration page (www.rkiinstruments.com/registration) to ensure warranty coverage and product support.

  • What should I do if the alarm sounds on my gas detector?

    If your instrument triggers an alarm, immediately evacuate the area to a fresh air environment and follow your company's safety protocols. Do not attempt to troubleshoot the device or ignore the alarm while in a potentially hazardous zone.
