Step 1 Power On
Press the power button located at the lower right of
the front panel.
Step 2 Initialization
When the unit is powered on, it undergoes an
initialization cycle during in which it polls the system
for available sensors and verifies communication with
those sensors. The instrument will also regulate the
sample line flow and once it reaches 28.3 ALPM the
initialization phase is complete.

Note
Other information available on the screen is the unit serial
number, software revision, machine identification number
and the total operating hours. See “Software Description”
page 41 for details.
Step 3 Establishing Zero Level
After initializing, the unit will automatically proceed
with establishing the zero level. This process takes
approximately 10 seconds. If it cannot establish a
zero, the operator will be prompted to retry up to three
times. The operator should press the Yes button to
retry or the No button to shutdown the instrument.
The operator will have to press the Ok button to
shutdown the instrument if the zero level cannot be
established at the last attempt.
Step 4 Main Menu
Once the zero level is established, the instrument will
display the main menu. The operator can then choose
to change parameters, such as the reporting function,
date and time, or the alarm settings. He must then
decide the method he wants to use to set the 100%
reference for the instrument.
Step 5 Selecting an Aerosol
Before proceeding with setting up the 100% it is good
practice to verify that the correct reagent is selected.
