Use Of The Internal Thermal Camera (Eclipse) - HT ECLIPSE HT9025 User Manual

5.14. USE OF THE INTERNAL THERMAL CAMERA (ECLIPSE)

1. Switch on the instrument in any position of the selector switch.
2. Press key IR/
3. Move the protection selector (see Fig. 2
4. Press key to enter the general menu to set the emissivity value of the object to be
tested, to activate - if necessary - measuring spots H (hot spot) and C (cold spot) and
the laser pointer, as described in §. 4.3.10
5. Frame the object to be tested, whose thermographic image will be displayed (see §
4.3.2) with automatic focusing.
6. In the thermographic image measuring spots H and C are respectively indicated with
red and blue cross pointers.
The instrument carries out an automatic autocalibration sequence approx.
every 10s (it cannot be disabled). This condition is also carried out during
the internal thermal camera
errors. The noise produced by the commutation of internal parts is not to be
considered as a problem of the instrument.
7. For accurate temperature measurements, make sure the surface of the measured
object is always bigger than the surface measurable by the instrument, which is given
by the instruments field of view (FOV). ECLIPSE has a field of view of 21° x 21° and a
detection vector of 80x80 (6400) pxl, as described in Fig. 43

8. The representation of the ratio D (distance from the object) / S (surface of the object)
for ECLIPSE provided with 7.5mm lens is described below
to activate the internal thermal camera.
