Troubleshooting and further Notes
OH or OL is displayed when the temperature being measured is
outside the range of the instrument (OL: colder than -40 °C resp.
OH: hotter than +580 °C). Only select targets which are within the
specifications. If a malfunction still exists, please contact our cus-
tomer support.
Observe the measuring distance/radius ratio in case the measur-
ing results are not comprehensible. Hold the thermometer closer
to the object to be measured.
A big difference between the emissivity of the object to be
measured and the preset emissivity of the thermometer (0.95)
can lead to imprecise measurements.
The thermometer should be allowed several minutes to stabilize
to the working temperature when it has been exposed to rapid
changes in the ambient temperature.
Do not expose the thermometer to strong magnetic fields or static
charges. This will affect the performance of the thermometer.
Make sure that there are no objects such as glasses, plastics,
vapour, dust, etc are in the space between the thermometer and
the object to be measured.
Cleaning and Storing
Only use a soft, lit free lightly moistened cloth to clean the
housing of unit. Do not use aggressive chemicals or abrasives
and do not use liquids.
Do not use force on the LC display when cleaning it.
Carefully clean the infrared sensor with a soft brush or with clean
compressed air.

the battery.
Store the unit indoors out of reach of children in a place that is
protected from moisture, dust, dirt and extreme temperatures.
