4. Use the Laser pointer to accurately target a spot. Press the Laser pointer
button to switch ON the Laser pointer. The camera’s Laser pointer in-
cludes a circular spot indicating the area that is being monitored for tem-
perature, 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 24:1 (TG267, TG165–X) or 30:1 (TG297) and
the minimum target distance is 26 cm (10.2 in.).
8. To measure higher than 752℉ (400℃) on the TG297 use the High Tem-
perature Switch, see Section 5.3 below.
9. The TG267 and TG165–X do not include a high temperature filter, do NOT
attempt to measure > 380℃ (716℉) on the TG267 or > 300℃ (572℉) on
the TG165–X.
10. If a measurement is out of range, the display will show ‘OL’.
11. To adjust the Emissivity, use the menu system (under Measurement).
12. To change the display color palette, use the menu system (under Image
Adjustments/colors).

NOTE
The camera’s reflected temperature setting is fixed at 77℉ (25℃) and may differ from the ac-
tual reflected temperature of any given application.
5.3 High Temperature Switch (TG297)
1. To access the high temperature mode of the TG297, slide the lever to the
right (to expose the red colour code).
2. The lever is located directly below the lens area and above the image cap-
ture trigger.
