OPERATING & MAINTENANCE TIPS

If the temperature of the IRT’s target is lower than -58°F (-50°C)—the lower

limit of the unit’s measurement range—“OL” will appear on the main readout.

If the temperature of the IRT’s target is higher than 1202°F (650°C)—the upper

limit of the unit’s measurement range—“OH” will appear on the main readout.

The IRTC659K cannot make accurate measurements if there is glass or plastic

between it and the target.

Clean the infrared sensor lens (Fig. 1, Callout B) 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 don’t 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.
