Both the Pt 100 RTD temperature sensor and associated electronics are very stable and should not require any calibration after the initial factory adjustment.
Long term stability of the ROTRONIC Hygromer HT-1 humidity sensor is typically better than 1 %RH per year. For maximum accuracy, calibration of the XB transmitter should be verified every 6 to 12 months. Applications where the XB transmitter is exposed to significant pollution may require more frequent verifications.
Calibration and adjustment of the HF7 can be done with either a PC with the HW5 or HygroSoft software installed or with another instrument such as the HP23 hand-held calibrator.
If so desired, transmission of the XB transmitter output signals can be validated by using the simulator function. The HW5 or HygroSoft software is required to enable and configure this function. When this function is enabled the XB transmitter generates fixed digital and analog signals as specified by the user.
