Gas, even under moderate pressures, can cause extreme bodily harm. Never allow any
gas stream to be directed at any part of your body.
Never expose the sensor to pressures above atmospheric pressure (0 psi) or you may
cause damage to the sensor and/or receive false readings. Damaged Sensors will not
provide accurate gas analysis. Inaccurate gas analysis can lead to serious personal
injury or death.
4.1. Programming Procedures
Press the “Prog” button until “Pr” appears on the display. The display will then
change to “AL 1” and alternate with the 3 digit set value.
It is possible to program:
o
AL 1 Minimum alarm point expressed in % of nitrogen concentration
o
AL 2 Maximum alarm point expressed in % of nitrogen concentration
o
FSC Value expressed in % of nitrogen concentration corresponding to the
current output full scale value (20mA). 20mA always correspond to 100%
nitrogen concentration.
o
O2c nitrogen sensor calibration point
At the end of the programming procedure the display will show “End” and the
instrument will display the nitrogen content of the gas mix.
