XT Display Unit Camera

The camera is default in the XT Display Unit. It is possible to buy an XT Display Unit without a camera. It cannot be retrofitted.

  1. Tap and . The camera is also available from the start view.
  2. Tap to take a photo.

The photo is saved in File manager as a .png file. It is named with current date and time. If you have an ongoing measurement (and using a layout that will include a photo), the latest photo is added to the report automatically. If a new photo is taken, the previous one will be overwritten.

It is also possible to add several photos to a report. Go to Report Overview.

XT Display Unit IR camera

The IR (thermal) camera is optional equipment (Part No. 12-0968) and cannot be retrofitted.

  1. Tap and . The camera is also available from the start view.
  2. Tap to start the IR camera. Allow the camera to acclimatise for about five minutes in the environment in which it is to be used. This will ensure an optimal IR measurement.
  3. Press to take a photo.

An IR photo is saved in the File manager as a .png file. It is named with current date and time. If you have an ongoing measurement, the photo is added to the report.

  1. Heat scale (when selected in Settings).

  2. Crosshair (when selected in Settings). This is where the temperature is registered (Temp, e and Tbkg).
  3. Tap to open Settings.
  4. Temp: The average temperature (in crosshair).
    e: The emissivity value.
    Tbkg: The reflected background temperature.

IR Camera Settings

Palette

Change the color presentation of the infrared images. Select between iron, glowbow, grey, rain or yellow.

Show/hide

If you hide the crosshair and/or metadata, it will not be shown on the saved image either.

Emissivity (e)

The emissivity value of the surface/object is captured by the crosshair. The correct emissivity value is important for an accurate calculation. Possible values: 0.01 - 1.00, but we do not recommend value below 0.6. The value is normally set from a list of emissivity values for some common materials.

  • 1.00 for a perfect blackbody.
  • 0.01 for a perfect shiny (in the infrared spectrum) object.

Background temperature (Tbkg).

The reflected background temperature of the surface/object. Can normally be set to the ambient temperature. Value <382ºC (720ºF). Has no effect when e = 1.00

Unit

Select Celsius or Fahrenheit.

Scaling

By default, manual scaling is not used and the heat scale of the image will adjust automatically from the lowest temperature to the highest temperature of the IR image.

If you select manual scaling, you can decide which temperatures you want to visualize.

  • Scale max: Enter a temperature (up to 450ºC).
  • Scale min: Enter a temperature (down to 0ºC).
