EMISSIVITY
Not all surfaces emit infrared energy at the same
level. A shiny surface will emit much less infrared
energy at a given temperature when compared
to a flat black surface. The UD70 has two preset
emissivity levels used to compensate for variances
in your target.
High (0.95) will work for most common surfaces and
is set as default for many infrared thermometers.
CHANGING SCALES
To change scales between degrees Fahrenheit
and degrees Celsius, press the mode button on
the panel, while the display is active. Even if the
trigger is released and the display is in its 60-second
automatic hold, you can convert the reading
between scales. Each time you press the scale
button, the 60-second hold will reset. The UD70
will default to the scale last used the next time it
is turned on.
USING THE LASER SIGHT & BACKLIGHT
The thermometer is classified as a "laser product",
and is regulated by the FDA. The laser and backlight
are always on when the trigger is pulled.
CAUTION: using controls, making adjustments,
or performing procedures in any manner other
than that specified herein may result in hazardous
laser radiation exposure.
LCD ERROR MESSAGES
