Cleaning

The presence of particulate matter, oil films, liquid water, or the residue from water
drops on the device optics can adversely affect its performance. The environmental
guard is designed to prevent solids or liquids from reaching the monitor's optical
system. Heating elements are also incorporated into the unit to prevent water con-
densation. Under severe conditions, however, some material may collect on these
surfaces and it may be necessary to occasionally check and clean the windows.
(1) Remove the environmental or flow cap.
Fig. 18 Remove Environmental Guard
(2) Place an opaque object [piece of paper, two fingers, etc.] between the light
source window and the mirror to completely obscure the light path for two to
three seconds [ fig. 19].
If the opaque object is left in the light path for longer than 10 seconds, an

Obscuration fault will be set on the mA output [ chapter 4.1].
The device enters the Cleaning Mode for 5 minutes.
