4.1 AutoCal
4.1.1 Top Level Menu and Programmer Function
With AutoCal activated, the AutoCal screen (see Figure 13) is displayed instead of the Programmer
Function Screen. The standard Programmer functionality, as described in section 3.4.3 is still available
but is accessed via the drop-down menu in the top left hand corner of the screen.
4.1.2 AutoCal Reference
The standard version of AutoCal uses the internal control HygroClip as its reference. AutoCal+ is an
extension to AutoCal which enables the selection of an external MBW/RHS dew point hygrometer as an
external reference. For more details on using AutoCal+, see section 4.2 . For a more in-depth discussion
of references and calibration traceability, please see Appendices A1: Calibration Reference Options and
A2: Temperature Control .
4.1.3 AutoCal Screen
As ROTRONIC probes are added via the USB ports, the individual probe slots are populated within the
AutoCal Screen. During an AutoCal calibration run, probes can be adjusted, or not, as desired, for each
probe. Select individual probes by selecting the “Adjust” button.
