Setting pre-alarm percentage
The BX308xp program allows a different pre-alarm threshold per each
connected probe.
Toxic gas Setting
To set other probes, use the RIGHT and LEFT buttons to move to probe 7 (in this case) (“E”). On the first line you
will see the gas percentage of “10% LEL”.
To change the percentage press “ENTER”.
The percentage is increased each time of 1%, starting from 3% of LEL up to a maximum of 16% of L.E.L.
The percentages are increased cyclically.
Use the arrow up to the right and press “ENTER” to return to the previous program.
When this screen appears, the cursor goes on probe 1, (in this case (“T”). On the first
line you will see the gas percentage of “150 ppm”.
To change the percentage press “ENTER”. The percentage is increased each time of 15
ppm, starting from 45 ppm up to a maximum of 240 ppm.
The percentages are increased cyclically.
