2.4.8 Ambient Temperature Compensation (T-Ambient)
Head types H001 and H002 only - The ambient temperature compensation is
factory preset as inactive. This value is normal for most applications.
However, in some applications the surrounding ambient temperature is
much higher than the target. If the target has an emissivity less than 1.0, it
will reflect a certain portion of the surrounding energy and cause an erro-
neous temperature reading. To avoid this error, set in the average surround-
ing temperature and the microprocessor will automatically compensate for it.
To set T-Ambient, complete the following:
1. Press and hold the button, and press the button, then release
them both. The Peak Hold display appears (as shown in Figure 15).
2. Press the button several times until the Ambient Compensation indi-
cator displays (Figure 18). The display shows either a “0” or “1” (default=
“0” - Off).
3. You can activate or deactivate Ambient Temperature Compensation by
using the up and down buttons. A number “1” means it is active; a num-
ber “0” means it is inactive.
