IMPAC pyrometer IGA 15 plus

10 Transport, packaging, storage

The instrument can be damaged or destroyed if shipped incorrectly. To transport or store the

instrument, please use the original box or a box padded with sufficient shock-absorbing material.

For storage in humid areas or shipment overseas, the device should be placed in welded foil

(ideally along with silica gel) to protect it from humidity.

The pyrometer is designed for a storage temperature of -20 to 70°C with non-condensing condi-

tions. Other kind of storage can damage or malfunction the pyrometer.

11 Maintenance

The pyrometer does not have any parts which require regular service, only the lens has to be kept

clean. The lens can be cleaned with a soft cloth in combination with alcohol (do not use acid

solutions or dilution). It is also possible to use standard cleaning tissue for glasses or camera

lenses.

It is recommended to send the pyrometer every two years to LumaSense for recalibration.

12 Trouble shooting

Before sending the pyrometer for repair, try to find the error and to solve the problem with the help

of the following list.

Temperature indication too low

• Incorrect alignment of the pyrometer to the object

⇒ New correct alignment to achieve the max. temperature signal

• Measuring object is smaller than spot size

⇒ Choose correct measuring distance

• Measuring object is not always in the measuring spot of the pyrometer (e.g. swinging wire or

pouring stream)

⇒ Use max. value storage

• Emissivity set too high

⇒ Set lower correct emissivity corresponding to the material

• Lens contaminated or scratched

⇒ Clean lens carefully

Temperature indication too high

• Emissivity set too low

⇒ Set higher correct emissivity corresponding to the material

• The measurement is influenced by reflections of hotter machine parts

⇒ Try to avoid the influence of the interfering radiation or change measuring position

Measuring errors

• Indicated temperature is decreasing during the use of the pyrometer, contamination of the lens

⇒ Clean lens

• Air contamination in the sighting path between pyrometer and object

⇒ Change position of the pyrometer with a clean sighting path

• Strong HF-interferences

⇒ Change position of the pyrometer
