Applications with changes in temperature
Frequent extreme changes in temperatures can temporarily cause measuring errors.
Temperature compensation takes place after a few minutes. Internal temperature
compensation is faster the smaller the change in temperature and the longer the time
interval.
For further information please contact your local Endress+Hauser Sales Center.
