PACT, Inc. Chronographs and Sky Screen Systems – General Troubleshooting

PACT, Inc. has been designing chronographs for years. This article covers common issues, troubleshooting steps, and support options for both current and legacy chronographs. Whether you’re dealing with a newer model or an older unit, we’re here to help.

General Troubleshooting:

  1. Low or Inaccurate Readings
    • Battery Check: Replace the 9V battery with a fresh, recently purchased one. Even stored batteries lose charge over time, which can affect accuracy.
    • Next Steps: If the battery doesn’t resolve the issue, it could be a sensor or internal problem. See “Repair and Trade-In Options” below.

  2. No Start Signal (Not Reading Shots)
    • Battery Check: Start with a new, fully charged 9V battery, as a weak battery can prevent shot detection.
    • Cable Inspection: Check the sensor cables for wear or loose connections. Wiggle them near the ends to find a “sweet spot.” If faulty, replacement sensors may be needed (e.g., Sky Screen Arms Replacement Kit for legacy systems).
    • Internal Issue: If the battery and cables are fine, the problem might be the chronograph’s circuit board. Newer models may qualify for repair; older ones may need a trade-in (see below).

  3. Adjusting Screen Separation
    • Process: To edit the Sky Screen separation:
      1. Ensure the unit is in Chronograph Mode.
      2. Press the “SET” key, enter the separation in inches (e.g., 18 for 18 inches), then press “SET” again to save.

  4. Software and Compatibility (Shot Browser)
  5. Powering IR Sensors

    • IR vs. Standard Sensors: Infrared (IR) Sensors work in darkness using their own light but can be overwhelmed by sunlight outdoors—monitor lighting conditions. Without power, IR Sensors function like standard sensors.

    • Portable Power Options: IR Sensors require a power source. Examples include:

Sky Screen Systems – Legacy Notes:

Older chronographs use legacy Sky Screen Systems. If damaged (e.g., shot), replacement black plastic arms are available but may need slight modification for fit.
