Corresponding temperature references integrated in the above may be used or additional external
temperature references employed (for example, platinum resistance thermometers (PRTs)).
It is vital to consider the comparison of temperatures measured by the reference, the HygroGen2 and
IUTs. Because RH is significantly dependent on temperature, temperature measurement should be
optimised to get meaningful RH results.
For more details, please see A1: Calibration Reference Options and Appendices D1 to D4 on
Uncertainty.
1.3 Optional Enhanced Features: AutoCal, External Reference, Range
Extensions and Remote Control
With the introduction of software version 2.0, the HygroGen2 comes with optional Enhanced Feature
upgrades: AutoCal and RH/Temperature Range Extensions. Version 2.1 has more additions to the
Enhanced Features range: AutoCal+ and Remote Control. Further enhancements are in development
and will be released in subsequent versions.
All Enhanced Features are activated by the application of a licence key, available via your ROTRONIC
dealer, and can be added to any HygroGen2. Under certain circumstances a service may be required.
Low Temperature and Humidity Range Extensions extend the limits of points that can be set on the
instrument, creating chamber conditions down to -5°C and from 2%rh up to 99%rh.
AutoCal allows you to pre-program a series of set-points and times, and record the instrument‘s
progression through them in a PDF Calibration Certificate which is written to an external USB disk
drive. Any values recorded on ROTRONIC HygroClip probes attached to the HygroGen2 via USB
adaptors are recorded in the certificate. Probes can be set to automatically adjust to match the
HygroGen2 reference probe at predetermined values.
AutoCal+ (External Reference) extends the functionality of AutoCal, by integrating MBW/RHS chilled
mirror hygrometers (supplied separately) as the external reference.
Remote Control gives the ability to remotely control the HygroGen2 over a network. As part of this,
there is a dial-back function so that ROTRONIC support personnel can log onto the instrument to offer
support. Support is limited to the settings of the HG2-S, the unit may require a service that can only
be carried out by trained personnel.
