MSA altair 5, Instruction Manual

Page: 15 / 245

The ALTAIR 5 IR is available with a maximum of five sensors, which
can display readings for six separate gases (one Dual Toxic Sensor
provides both CO and H2S sensing capabilities in a single package).
The ALTAIR 5 and ALTAIR 5 IR Detectors are available with either a
monochrome or color display.
While the instrument can detect up to 25 % oxygen in ambient air, it is
approved for use only up to 21 % oxygen.
The alarm levels for the individual gases are factory-set but can be
changed through the instrument Setup Menu. These changes can also
be made through MSA Link
TM
Software. Ensure that the latest version of
the MSA Link software has been downloaded from MSA’s website
www.msanet.com. It is recommended that after making changes using
MSA Link, the unit should be turned OFF and ON.
2.2 User Interfaces
Instrument operation is dialog driven from the display with the aid of the
three function buttons (see FIGURE 2-1).
2.2.1 Button Definitions
The ALTAIR 5 and ALTAIR 5 IR units use three buttons for user
operation. Each button can function as a "soft key", as defined
immediately above the button.
BUTTON DESCRIPTION
The Button is used to turn instrument ON or OFF and to confirm
user action selections.
▼ The ▼ Button is used to page down through data screens or to
decrease the values in Setup mode.
▲ The ▲ button is used to reset peak, STEL TWA and alarms
(where possible) or perform calibration in measuring mode. It is also used
as page up or to increase the values in Setup mode.
When the ▲ button and the ▼ button are pressed simultaneously while
in normal measure mode, the Setup Mode can be entered after the
Password is confirmed.
