Operation
3. Point the camera toward the test area and scan as desired. View the cam-
era image on the TG275 display.
4. Use the Laser pointer to accurately target a spot. Press the Laser pointer
button to switch ON the Laser pointer. The TG275 Laser pointer includes
a circular spot indicating the area that is being monitored for temperature,
utilizing DOE (Diffractive Optical Elements) technology. See the Laser
pointer image example below in Figure 5.2. If the Laser beam does not
appear when the button is pressed, check the menu system (under Device
Settings) to ensure that the Laser is enabled.
5. Use the cross-hair icon for reference only when targeting measurement
spots, as parallax errors affect targeting accuracy. If the cross-hairs are
not shown, check the menu system (under Measurement) to ensure that
the Center Spot (cross-hairs) function is enabled.
6. The temperature reading on the display represents the measurement of
the targeted spot. See Figure 5.1.
7. The distance-to-spot ratio is 30:1 and the minimum target distance is 10.2
in. (26 cm).
8. To measure higher than 752℉ (400℃) use the High Temperature Switch,
see Section 5.3 below.
9. If a measurement is out of range, the display will show 'OL'.
10. To adjust the Emissivity, use the menu system (under Measurement).
11. To change the display color palette, use the menu system (under Image
Adjustments/colors).
