1. Description
The Megger TC3231 is a professional, easy to use, thermal imaging camera. Fast accurate readings are possible,
covering a wide range of surface temperatures with on-screen spot as well as max/min temperature measurement and
tracking. With the added convenience of image blending provided by combining a visual and full infrared image on
screen, troubleshooting and pinpointing problems is made far simpler. Captured images can be stored on the included
SD card for later viewing on MAC/PC. A range of thermal image display palettes, high/low user preset alarms and fully
adjustable emissivity make the Megger TC3231 an extremely versatile instrument for multiple applications.

To capture the image and save it to memory:
Unclip and retract the lens cover. Point the camera at the object or area of
interest and pull the measurement trigger.
Press the Enter button to save the image.
Press the Menu button to cancel.
The image is now saved as a .BMP file on the Micro SD memory.
Note: Image numbers are automatically assigned by the camera.
To view the saved images use the setup menu MEMORY option.

5.1 Image Blending
Image blending makes it easier to understand infrared heat maps through the use of an aligned visible image and full
infrared heat map. The product captures a visible image with each infrared heat map to clearly show the target area.
It is possible to adjust the blending between visible images to a full infrared heat map in increments in the measure
mode.
The UP / DOWN buttons select the blending in increments. Once the required blend is selected, pull the measurement
trigger and then press the Enter button to store the image.
Note: Images for illustration only

7. Setup Menu Emissivity
Note: All menu settings are retained when the instrument is
switched off
Press the MENU button to enter the setup menu. Use UP /
DOWN navigation buttons to highlight EMS.
The current emissivity is displayed. Press the Enter button
and press the UP / DOWN navigation buttons to adjust
emissivity. Press the MENU button; the new value is now
stored and displayed. Press the MENU button again to exit
the setup menu.
7.1 Emissivity
Definition of emissivity is the ratio of the energy radiated from a material’s or object’s surface to that radiated from a
perfect emitter, known as a blackbody.
It is a value between 0 (for a perfect reflector) and 1 (for a perfect emitter).
The emissivity of a surface depends on two variables; the material and the nature of the surface itself. A polished metal
surface will have a low emissivity, while an oxidized metal surface will have a fairly high emissivity. The emissivity is also
dependent on the temperature of the surface.
Typically, 90% of organic materials and painted or oxidized surfaces have an emissivity of 0.95. Inaccurate readings
will result from measuring shiny or polished metal surfaces. To compensate, cover the surface to be measured with
masking tape or matt / flat black paint and allow time for the tape/paint to reach the same temperature as the material
underneath it. An accurate measurement can then be made of the taped/painted surface.
