Setting the Temperature Scale
The Imager displays temperatures using either the Celsius or Fahrenheit temperature
scales. The default temperature scale is Celsius.
1. Press G (
MENU
) five times from the Home display to access the temperature
scale function.
2. Press H
(TEMPSCALE
) to toggle the temperature scale between Fahrenheit and
Celsius.
Setting the Level
In Manual mode, you can define Level and Span values manually. Manual mode allows
you to bring both MIN and MAX values to the desired cut-off levels and to adjust the
temperature interval to a minimum to maximizing color resolution. Manual mode
provides the best possible image definition as to the specific inspection situation at hand,
both from a thermal resolution and temperature level standpoint.
Level is the median point of a given temperature scale. For example, if the unit is
currently in Automatic mode, and there is a given thermal scene with MIN and MAX
temperature limits, the moment you switch the unit to Manual mode, the Level value is
set by the Imager according to the following formula:
2
Max Span
Level =
+ Min Span
