Reveal: Troubleshoot Guide

Incoming Inspection

  • Follow these steps when inspecting a unit if an issue should arise:
    • Inspect the entire unit for damage with attention to:
      • Garage Door
      • Window
      • Sides of Enclosure
      • Front Bezel

 

Power/Battery Issues

  • If the unit and flashlight don’t turn on:
    • Plug the device into a charger for a minimum of 30 minutes.
    • If the charging symbol appears on the LCD right away, the unit was likely drained of all power.
      • When the unit is completely drained, it can function incorrectly until fully charged and power cycled.
    • After charging, unplug the unit and turn the device on. If the device fails to turn on, attempt a power cycle.
  • If the unit doesn’t turn on but the flashlight still operates:
    • Charge the unit for a minimum of 30 minutes.
    • After charging, power cycle the unit.
    • If the unit doesn’t turn on but you can hear the clicking sound of the shutter moving, it’s likely the LCD is no longer functioning.

 

Clicking Noise

  • There may be a clicking noise present when operating the device, this is NORMAL. The clicking is a shutter actuating inside the unit and is used for ‘correcting’ the image. The clicking frequency decreases the longer the unit is on.

 

Thermography Accuracy

  • If a calibrated heat source isn’t available, two heat sources you can check are:
    • Boiling Water
      • Water that is at a full boil should measure roughly 100°C/212°F depending on various environmental factors.
    • Body Temp
      • NOTE: Measuring the human body can have a vastly different reading depending on where you are looking. The most reliable location is the tear duct. The tear duct should be the closest point to 36°C/97°
    • NOTE: If source temperatures aren’t calibrated, getting close to their values would be considered passing. Typically, thermography failures are incorrect at an extremely noticeable level (i.e. measuring > 50° off from expected temperatures).

 

Focus Verification

  • Verify that you can focus on an object that is ~20’ away.
    • Reveal Series units are fixed focus. If the unit is out of focus, inspect for damage to the lens.

 

Image Quality Issues

  • Image Quality Evaluation
    • Do not judge the image quality by looking at a low contrast scene (i.e. covering the unit up with your hand or looking at a wall/desk). To effectively screen out image quality issues, look at a high contrast scene (i.e. a hot cup of coffee or your hand, in front of a cold background).
  • A small amount of image artifacts are allowed in the image. If excessive pixilation or flashing rows/columns are present, the unit should be considered a failure.
    • Exception: If a cluster of pixels are isolated to a corner or edge of the image, this is typically indicative of a dropped unit.

 Example of Flashing Line

  • Grey Image
    • If the image looks pixelated and the shutter isn’t making a clicking noise, it’s likely that the shutter is no longer actuating.
  • System Noise
    • System Noise is defined as pixelation throughout the image. When looking at a scene with low contrast (i.e. looking at a flat wall or covering the lens with your hand), there will be a small amount of noise present in the image.
