6.1 Safety
Attention during pyrometer services:
Should the pyrometer be integrated in a running machine process, the machine has to be
switched off and secured against restart before servicing the pyrometer.
6.2 Service
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). Also standard cloths for cleaning glasses or photo objectives can be
used.
The lens of the 10 : 1 sensor head has an anti-reflective coating which appears slightly colored.
Caution:
Be extremely careful - this layer can easily be rubbed off - this will greatly
affect the measuring results!
