 5.  WORKING WITH THE ANALYSER

 5.1.  Starting up the analyser

To start up the analyser you have to use the switch placed on the right side of the

front panel. If you did not use the mains power cord, the analyser will start, using its built-

in   rechargeable   battery.   When   the   power   cord   is   used,   the   analyser   will   charge   the

battery regardless from the power switch being in ON or OFF position.

At   first,   a   welcome   screen   will   be   displayed   (like   the   one   below)   and   afterwards   an

information about a process of gas sensors zeroing should be visible.

Drawing 4.

Welcome screen visible straight after the analyser is starts.

Zeroing   procedure   takes   120   seconds   and   is   necessary   for   measurements

precision. A countdown timer visible on the screen shows the time remaining to the end of

this process. Afterwards the analyser is ready to work, with a screen of measurement's

parameters displayed.
