14.5.1.2 Types of temperature ranges
Type
Name
Example Explanation
1
Characteristic tempera-
ture range
–40°C to +350°C (–40°
F to +662°F)
All temperatures the
camera can register.
This range is the total
sum of the temperature
ranges (type no. 2
below).
2 Temperature range +10°C to +50°C (+50°F
to +122°F)
The span of tempera-
tures that the camera
can register with the
current settings.
This type of range is a
subrange to type no. 1
above.
3 Temperature span
+23.8°C to +25.9°C
(+74.8°F to +78.6°F)
The range of tempera-
tures that the camera
registers when aimed at
a particular scene with
a particular temperature
range set.

14.5.2.2 Explanation
1. Currently set minimum temperature in the temperature span (= range of type 3 in the
table 14.5.1.2 Types of temperature ranges, page 39).
2. Currently set maximum temperature in the temperature span (= range of type 3 in the
table 14.5.1.2 Types of temperature ranges, page 39).
3. Currently set maximum temperature in the range that the camera can register with the
current settings (= range of type 2 in the table 14.5.1.2 Types of temperature ranges,
page 39).
4. Indicator that represents the temperature range (= range of type 2 in the table 14.5.1.2
Types of temperature ranges, page 39).
5. Indicator that represents the temperature span (= range of type 3 in the table 14.5.1.2
Types of temperature ranges, page 39).
