APPLICATION SOFTWARE
The
Calibration Correction
window is a utility that allows an authorized user to input
calibration information in order to effect a real-time correction of the displayed, charted
and logged data within the Opti-Soft application software.
Data for dew-point temperature and ambient temperature, both in units of °C, may be
entered for correction purposes, along with the original Calibration certi
fi
cate reference
number and date of calibration, providing full traceability of data. Once the correction
data has been applied, by clicking on the check box, the main
Virtual Hygrometer
window will indicate that corrected data is being displayed and will show the Calibration
certi
fi
cate number and date. This information is also saved to the
Log
fi
le for data
export.
Figure 26 shows the
Calibration Correction
window. Four sets of data may be entered:
DP Ref
Dew-point data for the reference hygrometer used to
calibrate the Optidew (sometimes called the actual
dew point or the standard)
DP Reading
Measured dew-point value of the Optidew under test
Temp Ref
Temperature data from the reference thermometer
Temp Reading
Measured temperature value of the Optidew under
test
Data can be entered for between 3 and 11 different dew-point and temperature
calibration points. If no data is inserted, no calibration correction is possible. Data
should be entered with the highest dew-point and temperature values at the top of
the page, in descending value order to the bottom. If out-of-sequence data or spurious
characters are entered, the software will raise a warning message and bad data must
be re-entered.
The
Calibration Certificate Number
fi
eld is an optional entry
fi
eld and is alphanumeric.
Any information entered into this
fi
eld will be displayed on the main
Virtual Hygrometer
window when calibration correction is enabled. In addition it will be saved to the
Log
fi
le. Similarly, the date of calibration may be entered for display and logging when
correction is enabled.
