6.3 DISPLAY (HygroLab 2 and 3)
Definition
This function is used to select which parameters the instrument displays. The display mode is
specified globally for all probes connected to the instrument.
Selections
- Measurement
Relative humidity (in %RH or as water activity: Aw) and temperature or the parameter
measured by any third party probe connected to the instrument.
-
Calculated + Temperature
Calculated parameter (as selected under CALCULATE) and temperature. This selection is
not available with third-party probes.
- Calculated + Humidity
Calculated parameter (as selected under CALCULATE) and relative humidity. This
selection is not available with third-party probes.
-
User Calc
User defined calculation such as the difference between temperature and dew point of any
probe. The display shows only the calculated value. See the separate HW4 manual for
instructions on how to program the HygroLab 2 or 3 to compute a user specified
parameter.
6.4 ADJUST M.PT
Definition
The Adjust M.PT function permits the full calibration of any ROTRONIC HygroClip digital probe
against a known reference environment. This function is designed to permit calibration at 2
temperature values and at up to 4 relative humidity values.
Selections
The Adjust M.PT function offers the following choices (use the UP and DOWN keys):
RHS:
Humidity calibration using the ROTRONIC Humidity Standards 1)
Humidity: Humidity calibration using any suitable reference environment
Temperature: Temperature calibration using any suitable reference environment
1) For humidity calibration, ROTRONIC offers convenient, certified humidity standards to generate
known humidity values (for details, see Humidity Calibration).
