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:

Max Span

Level =

+ Min Span
