isnotexceeded.
Ifthemax.ambienttemperatureisexceeded,youmusttakesuitable
measures to protect the instrument against overheating.
You can protect the instrument by providing a suitable insulation
against the heat or mounting the instrument further away from the
heat source.
Make sure these measures are taken into account already in the plan-
ningstage.Ifyouwanttocarryoutsuchmeasureslateron,contact
our specialists to ensure that the accuracy of the application is not
impaired.
Ifthesemeasuresarenotsucienttomaintainthemax.ambient
