2.6. Displaying points at the same temperature in the image

In the Main/Display/Cursor menu, choose the Isothermal cursor  it marks with another palette of colours the points

at the same temperature to within a given tolerance. Selection of this mode requires two validations of the menu item

with the F2 key: one to activate selection of the colour representing the temperature (Up/Down keys to scroll

through the colours) and one to validate the choice and start the function).

Up/Down keys  adjust the temperature

Left/Right keys  adjust the tolerance

If a Bluetooth device provides a Dew Point temperature that has been selected for influence, the reference temperature is this

measurement (a logo precedes the value). The up / down keys (see above) have no action and the isotherm collects all the

points whose temperature is lower than the reference. Tolerance only increases this value.

2.7. Freezing the colours representing the temperatures

By default, assignment of the colours is automatic and is recalculated for each image as a function of the temperatures of the hot

and cold spots in the image.

In consequence, a given colour does not necessarily represent the same temperature from one image to another, if the hot and/or

cold spots change.

If you want the colours always to represent the same temperatures, the palette must be frozen (the min. and max. temperatures of

the palette remain constant, whatever the hot and cold spot temperatures in the image).

 There are two ways to freeze the palette:

- either using the F2 or F3 key, when its function is

- or from the Main/Parameters menu, by validating the item with the F2 key to change its value to "Manual"

(Up/Down keys).

When the palette is frozen, a red padlock appears on the palette; the min and max values are also red.

When the mode is entered, the minimum changes to edit mode for a few seconds (on a blue ground with the symbol )

so that its value can be changed (Up/Down keys).

To modify the max., a simple press on Right (when min. is in edit mode) edits the value. If there is no action on the

keypad for a few seconds, the edit mode disappears.

To re-edit a value, another press on the F2 or F3 key with the function , or another validation of the item

in the Main/Parameters menu, returns the min. value to edit mode.

 To exit from the frozen palette mode, the following steps are necessary:

- if not in edit mode two successive presses on F2 or F3 having the function

- if in edit mode a single press from the edit mode or, from the Main/Parameters menu, by editing the item of

the Main/Parameters menu to restore the value "Automatic".
