Size of measuring surface - distant-to-spot ratios (D/S)

In order to get accurate measuring results, the object to be measured must be larger than the
measuring surface of the infrared thermometer. The detected temperature is then the average
temperature of the measured surface area. The smaller the object is the shorter the distance to
the infrared thermometer should be. The exact size of the measurement area can be seen in the
following diagram. This is also printed on the outside of the instrument.
For exact measurements, the object to be measured should be at least twice the
size of the measured surface area!

Maintenance and cleaning

To avoid electrical shocks, do not allow liquid to penetrate the housing.
| Clean the housing at regular intervals using a dry cloth without any cleaning agents. Do not
use abrasive, scouring or solvent-based cleaners.
Blow loose dirt particles from the IR lens. Brush of any remaining dirt using a fine lens brush.

Changing the batteries

If the device is not to be used for a long time, remove the batteries and store the device in a place
that is neither too hot nor too humid.
Do not leave used batteries in this device. Even anti-leakage batteries can corrode and release
chemicals which can damage both the device and your health.
