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
- Inspect the entire unit for damage with attention to:
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).
- Boiling Water
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.
