Press in and hold the black Select switch on the front of the instrument to bring up the
LCD Menu. See the next section for a description of how to operate the instrument
using this menu.
The user’s ozone monitor, or other experimental system, can be attached to the Model
306 OCS
TM
to receive air containing calibrated amounts of ozone. Alternatively, a 3-
way valve inside the Model 306 OCS
TM
can be set so that air from a sampling inlet on
the back of the instrument bypasses the Model 306 and is routed to the user’s ozone
monitor or system. When the Model 306 OCS
TM
is turned off, or in hibernation mode
(discussed in Section 5.3), the valve is set so that air is routed from the sampling inlet.
This permits the user to leave the Model 306 OCS
TM
plumbed in-line with their ozone
monitor or other system when the Model 306 is not in use.
