6 Maintenance
6.1 Periodic calibration check of the HygroClip 2 probe
Both the Pt 100 RTD temperature sensor used in the probe and associated electronics are very stable and
should not require any calibration after the initial factory adjustment. Long term stability of the ROTRONIC
Hygromer humidity sensor is typically better than 1 %RH per year. For maximum accuracy, calibration of the
probe should be verified every 6 to 12 months. Applications where the probe is exposed to significant pollution
may require more frequent verifications.
6.2 Cleaning or replacing the probe dust filter
See document E-M-HC2 Probes-V1
