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
ENTER
. The display jumps to the Pathlength
Display. To change the absorbance values, press
1
. The Humidity Range Select Display
appears (see Humidity Range Select Display, below).

Humidity Range Select Display
Select the desired range (1, 2, or 3). The Humidity Parameter Select Display appears (see
Humidity Parameter Select Display, below).

Humidity Parameter Select Display
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
ESC
to return to Humidity Range Select and
ESC
again to return to Humidity
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.
