Help with Thermal Imagers

Have a laser rangefinder question? We've include some of the the most common rangefinder questions we get asked below for quick reference, but click 'Find your laser rangefinder' below for in-depth guides and manuals specific to your model.

Is it for medical use?

No. MILESEEY Thermal Imaging Cameras are designed for building, HVAC, electrical, industrial, and educational use—not for medical screening.

Why does the temperature reading seem inaccurate?

Temperature accuracy can be affected by improper emissivity setting, measuring distance, ambient temperature, or range selection. Make sure to set the correct emissivity value for the material you’re measuring (you can find reference values in the user manual), keep measuring distance within limit, and ensure the ambient temperature and measurement range are set correctly. Adjusting these parameters will help you obtain more accurate temperature readings.

Why should I let the camera acclimate before use?

When moving between hot and cold environments, let the camera stabilize for 10–15 minutes and wipe any lens condensation for accurate readings.

What emissivity should I start with?

Begin at ε = 0.95 for painted drywall or wood.
For shiny metals, place a piece of black matte tape on the surface and measure from that spot.

How do I set reflected temperature (Tref)?

For indoor accuracy, set Tref close to room temperature and avoid capturing reflections from hot objects or lights.

Which color palette should I choose?
  • White/Black Hot: electrical panels, motors
  • Iron/High-Contrast: roofing, insulation, and envelopes
  • Rainbow: detecting moisture trails or subtle temperature gradients
How should I set the span or temperature range?

Auto mode works for quick scans, but once you detect an issue, lock the span for consistent comparisons.

What’s the minimum focus distance?

It depends on your model’s focus range. If you’re too close, step back slightly and use digital zoom to maintain clarity.

Why should I record baselines?

Capture normal temperatures for panels, bearings, or rooms.
Comparing future readings to these baselines reveals true changes, not just isolated numbers.

Any workflow tips for HVAC or moisture checks?

For HVAC: scan supplies → returns → coil face → duct joints.
For moisture: scan after rain or when the indoor/outdoor temperature difference is strong.

What are the electrical safety guidelines?

Use the camera to maintain a safe distance, but still follow NFPA 70E / OSHA PPE and clearance standards.

Can it see through walls or glass?

No. Thermal imaging only shows surface temperatures.
Use it to infer hidden issues, then confirm with appropriate tools or meters.

Why do my readings drift right after I walk in from the cold?

Let the camera acclimate 10–15 minutes; temperature sensors can stabilize.

How do I measure shiny copper or aluminum?

Attach a small piece of matte tape to the surface, this helps the laser detect it accurately and ensures reliable readings.

Can I find hidden water leaks?

Yes. Scan for cooler areas compared to surrounding surfaces, then confirm with a moisture meter before opening the wall.

When should I choose TR20 Pro over TR10?

When you need clearer thermal detail, dual-light fusion and video for daily professional use.

How do I use dual-light fusion effectively?

Simply switch the image mode to Fusion to enable dual-light fusion.

Best HVAC workflow?

Scan supplies/returns, log temperature difference, check coil face, then inspect duct leaks with a pressure test.

Is 256×192 enough for home inspection?

Yes for most building/HVAC/electrical tasks; move closer for detail and use proper span settings.

Best palette for moisture hunts?

Rainbow or Iron with a tight span; confirm with a moisture meter.

How do I reduce hand shake blur?

Use a strap or hold it with both hands; short video bursts help spot intermittent issues.

Why choose 384 over 256?

More pixels provide greater detail at the same distance, especially useful for complex inspections.

How to avoid blooming on very hot objects?

Switch to high-temp range and widen span before aiming.

Does dual-light help with reporting?

The overlaid images make component identification clear for non-technical clients.

When is fusion mode most helpful?

For identifying exact components in cluttered areas—pipes, conduits, or mixed materials.

How do I keep overlays accurate?

Avoid extreme angles; keep distance consistent so IR and visible align.

Why does my overlay look misaligned?

This may happen if the image mode is set to Fusion Rate. Try switching to another image mode to check if the alignment returns to normal. If the issue persists after adjustment, the device may require servicing. Please contact our support team for assistance.

Laser Measure

Why are my readings inconsistent outdoors?

Use delayed capture and a matte target card. Shoot from the shade, and mount the device on a tripod in windy conditions.

Why can’t it measure through chain-link fences or brush?

The laser beam passes through gaps. Aim at a solid surface behind or tape a target card to the spot.

Why do glass or mirrors give incorrect readings?

Avoid shooting directly at reflective surfaces. Place a matte tape patch on the target and measure to that point instead.

Why are readings too short or long on glossy tiles?

Glossy tiles cause specular reflections. Apply matte tape and re-measure at a slightly off-normal angle.

Why is the laser beam invisible in daylight?

This is normal. In bright light, rely on the crosshair or target card rather than the visible laser dot.

Why is the side laser alignment hard to see at noon?

Shade the window with your hand or hat, shorten the measuring distance, and aim at darker or matte surfaces.

Why do results change when I flip the device?

You likely didn’t switch the measuring reference. Set the front, back, or tripod reference correctly in the settings menu.

Why does the camera crosshair seem off-center?

That’s parallax. Hold the device square to the surface, avoid steep angles, and re-center the crosshair before measuring.

Why won’t Bluetooth pair?

Toggle Bluetooth off and on, forget and re-add the device, then reboot. Check app permissions and ensure firmware is up to date.

Thermal Imagers

Why does everything look the same color?

Your span is too wide—narrow it or switch palettes to increase contrast.

Why do I see false hot or cold spots?

They’re likely reflections. Change your viewing angle—if the spot moves with you, it’s not real.

Why do shiny metals read so cold?

Low emissivity. Apply matte black tape and set emissivity to around 0.95.

Why does the image look grainy?

The temperature difference is small or the scene is dim. Tighten span and move more slowly when scanning.

Why does the camera click repeatedly?

That’s the FFC (flat-field correction) normalizing the image—especially common during warm-up.

Why do I get over- or under-range warnings?

Switch to high-temperature mode for very hot objects, or let the camera acclimate before use in cold rooms.

Why does the lens fog after moving from heat to AC?

Allow the camera to stabilize naturally. Don’t wipe immediately—use a dry microfiber after fog clears.

Why won’t USB or Wi-Fi connect?

Reboot the camera and PC/app, use the supplied cable, and ensure both firmware and software are updated.

Why do outdoor scans appear cooler on windy days?

Wind removes surface heat—shield the area or notes wind effects in your report.
