For example, if the drift value was set to 25 percent, a drift flag is generated if the
absorbance at the reference wavelength is over 0.1245 AU or under –0.0969 AU.
Humidity Compensation Summary
The Humidity Compensation Summary allows reviewing the humidity compensation data
for the application. To accept this data, press
ENTER
. The display jumps to the
Pathlength Display. Press
1
to change the data in the Humidity Compensation Summary.
The Humidity Compensation Mode Display is presented (see Humidity Compensation
Summary Display, below).

Humidity Compensation Summary Display
Humidity Compensation Mode
Humidity Compensation Mode sets this mode off or on. The last mode condition
configured is shown on the display. If this is the mode condition for the present
application, press
ENTER
. The display changes to the next parameter to be configured.
Press
1
to change the mode condition. The Mode Select Display appears. Select the
condition for the application (Off or On). The display responds "-ACCEPTED-" and
then changes to the next parameter to be configured.
Humidity Wavelength
Humidity Wavelength enables specifies the humidity wavelength (usually the humidity
filter wavelength of 1.859

m). The last humidity wavelength configured is shown on
the display. If this is the desired wavelength, press
ENTER
. The display changes to the
next parameter. Press
1
to change the wavelength. The Wavelength Enter Display
appears. Key in the desired wavelength (in

m) and press
ENTER
. If the entry is valid, the
display responds "-ACCEPTED-" and changes to the next parameter to be configured.
