4.2.2 Measurement Type and Corrections
AutoCal+ gives you the choice between reading the RH value as determined by the external reference
directly or by entering a table of dew point and external temperature probe corrections from the
MBW/RHS dew point mirror’s calibration certificate.
Please note that, by design, the MBW/RHS will not display corrected values itself. This is so that a
calibration history can be built up, easily demonstrating the negligible drift over time of the chilled
mirror instrument and so the drift component of an uncertainty budget minimised.
Figure 25: Measurement Type
Select the desired Measurement type: Dew Point or Relative Humidity. If selecting Dew Point, please
proceed to the Corrections section to enter calibration certificate data. The choice is recorded on the
certificate.
