If the temperature of the IRT’s target is higher than 1472°F (800°C)—the upper limit of the
unit’s measurement range—or lower than -58°F (-50°C)—the lower limit of the measurement
range—“OL” will appear on the main readout.
The IRT730K cannot make accurate measurements if there is glass or plastic between it and
the target.
Clean the lens of the infrared sensor lens (Fig. 1, Callout 2) often—but never use a solvent.
Abrupt temperature changes will cause condensation and possible vapor penetration. Clean
the LCD after the vapor evaporates. Blow off loose particles with clean, compressed air. Gently
brush remaining debris away with a lens hair brush.
To clean the housing, use a moist cotton swab or wet sponge. Avoid excessive amounts of
water and corrosive gas or liquids.
Remove the battery if you do not expect to use the IRT for an extended period of time (months
or years).
Do not drop or disassemble the unit or immerse it in water.
