3.2.2. Custom Compensation Settings
Influencing parameters should be adjusted from their defaults when:
Environmental conditions are significantly different from default settings for emissivity, relative humidity,
temperature, and distance
High measurement accuracy is required
To change these settings, select Influence in the Target menu and then press
F2
. Ensure the setting is User; if
not use the up or down button to select this option. This enables you to change the following parameters:
•
Emissivity
: Choose from a list of materials or enter a value. You can modify three “user” values by
pressing the right button to enter the value. Then press the up/down buttons to change it, and
F2
to
save the change. After you save the emissivity value, it appears in the status bar. Allowable emissivity
values are from 1.00 to 0.05.
•
Distance
can be set from 1.6 to 3280ft (0.5 to 999.9m). Default is 6.6ft (2m).
•
Humidity
can be set from 0 to 100%. Default is 55%.
•
Temperature
can be set from 5° to +132°F (-15° to +55° C). Default is 55.5°F (13°C).
Note that you can also use measurement data provided by compatible Metrix ASYC IV Multimeters to
compensate for environmental factors (see §6.3.5). This requires connecting the meter to the camera via
3.3. Tripod
To improve the sharpness and accuracy of the measurements, it is possible to use a tripod for image stabilization.
The camera can be mounted on a tripod equipped with a standard ¼-inch mounting head. Attach the camera to
the tripod by screwing the tripod mounting screw into the threaded receptacle in the battery compartment cover
on the base of the camera handle (see below).
