When the thermal imager switches mode, a momentary interruption of the displayed image
may be experienced.

Colour Temperature Scale Indicator
The graduated scale colour palette provides a visual
indication of the range of scene temperatures
detected, enabling rapid recognition of hot spots.

Direct Temperature Measurement (DTM)
1)
Aim the crosswire directly over the object
to be measured.
2)
Read the temperature.
Notes
The measured temperature is based on an
assumed target emissivity of 0.95.
The measurement indicated is not a measure of air
temperature.
Unless specified otherwise at the time of order, the unit of measurement, in terms of degrees
Centigrade or Fahrenheit, is preset at the factory to the normal standard for the designated
country.
In order to obtain a temperature measurement of a hot object in a scene, the thermal imager
may switch between different sensitivity modes, dependent on the scene conditions at the
centre of the cross wire. This is completely normal and the thermal imager will revert to the
appropriate sensitivity mode once the hot object is removed from the scene.
