Chapter 7 Configuration and Setup
Humidity Absorbance
Humidity Absorbance specifies the coefficient for a P, Q, and R parameter or the
maximum absorbance value, any of which may be assigned to Range 1, 2, or 3 for the
application. The last humidity absorbance value for each range configured is shown on
the display. To accept this data, press
Display. To change the absorbance values, press
appears (see Humidity Range Select Display, below).
Select the desired range (1, 2, or 3). The Humidity Parameter Select Display appears (see
Humidity Parameter Select Display, below).
Select the desired parameter (P, Q, R, or Absorb Range). The Humidity Parameter Enter
Display appears. Key in the desired parameter coefficient (in the form 1.123456E-07)
and press
ENTER
Note : Use the down arrow key for a minus sign.
If the entry is valid, the display responds "-ACCEPTED-" and then changes to the
Humidity Parameter Range Select Display. Another parameter can be selected, or press
to return to Humidity Range Select and
ESC
Absorbance. Pressing the down arrow key at this point, goes to the next parameter,
Pathlength.
Normal practice is to set absorbance range 1 to 4.8000 AU, and to set its P value to 1.0
During analysis, this copies the absorbance data to the humidity data for later use.
