Setting The Scale

The active scaling mode is displayed bottom right:
A - automatic scaling, M - manual scaling and S
- ScaleAssist.
Automatic scaling continuously adjusts the scale
to the readings presented, and the color assigned
to a temperature value changes.
Manual scaling defines fixed limit values, and the
color assigned to a temperature value is fixed (im-
portant for visual image comparisons).
ScaleAssist, is a standardized scale set based on
the inside and outside temperature.
Scaling influences the way the infrared image is
shown on the display but does not affect the
recorded measuring values.

tral scale depending on the inside and outside
temperature. This is useful in identifying leak paths
