7 Maintenance

7.1 Calibration Service

The instruments are calibrated at the light of

a scientific standard lamp having a colour

temperature of 2856 K, fully in accordance with

the PTB standard.

Depending on how the instrument is being used

we recommend a recalibration interval between

12 and 18 months.

For this purpose please contact our

Calibration Service Department

(telephone +49 911 8602 172).

7.2 Cleaning and Maintenance

Keep the instrument dry and clean, away from

dust. Avoid exposing the sensor to unnecessary

light.

Please use a slightly damp cloth only for cleaning

the plastic surfaces; avoid the use of cleaning

agents or other strong chemicals. The lenses

should be cleaned with a special cloth or brushes

as used for optics.
