2.5 Backlight
The backlight can be manually activated with a quick push of the button. The
backlight remains ON for a certain time, depending on the instrument settings.
2.6 Fresh Air Setup (FAS)
This check eliminates background contaminants, reducing the possibility of
inaccurate readings.
The Fresh Air Setup zeroes toxic gas sensors. The Fresh Air Setup will not func-
tion if it is activated in a non-fresh air environment. If a dangerous level of gas
is present, the device will ignore the Fresh Air Setup and go into alarm.
2.7 Bump Test for Sensors with XCell Pulse Technology
Sensors with XCell Pulse Technology can be bump tested with a combination
of a pulse check and a flow check.
First, the device carries out an electronic pulse check of the sensor. Second, the
user executes a flow check by exhaling onto the face of the device.

3.1 Environmental Factors
A number of environmental factors may affect the gas sensor readings,
including changes in pressure, humidity and temperature.
Temperature Changes
The sensors have built-in temperature compensation. However, if temperature
shifts dramatically, the sensor reading may shift. Zero the device at the work site
temperature for the least effect.
3.2 Settings
Any changes of the device settings can only be carried out using the MSA
Link™ software. Ensure that the latest version of the MSA Link software is used.
The MSA Link application is available free on
