START UP
Perform the following steps to start up your monitor. Refer to
Figure 2-1 as needed.
CAUTION
Perform start up only in a fresh air environment.
1.
Flip open the housing gasket flap that covers the operator
controls, and move the power switch toward the sensor to
turn the monitor on. The unit should sound a single audible
tone, and display the installed version of software. A
number will then be displayed. Allow a few seconds for the
reading to stabilize, then check the display. If your HS-95 or
CO-95 shows a reading of 0 PPM, or your OX-95 a reading
of 20.9%, proceed to Step 4. If the reading is anything other
than this, perform Step 2 or 3, as appropriate.
2.
Zero the HS-95 or CO-95 by pressing the ZERO/- button
until the PASS message appears (about 5 seconds).
3.
Span the OX-95 by pressing the SPAN/+button until the
PASS message appears (about 5 seconds).
4.
Close the operator controls flap. Your monitor is ready for
use.
