A typical sign for when lifespan of the O
readings and inability to set the 17.4 mA signal even with the SPAN potentiometer
in max position.
1
Connect a Multi-meter (set to mA) to the
test points and adjust the readout on the
"SPAN" pot to 17.4 mA when normal
breathing air is present.
1.4 Calibrating the sensor (Zero calibration)
For Zero adjustment a Nitrogen mix should be used, with a pure N
concentration.
A gas bottle with Hydrocarbons in N
zero per cent.
We recommend the Consilium article no. 5201006-00A with 100% N
1
Connect a Multi-meter (set to mA) to the
test points.
2
Connect the gas bottle and open the
regulator valve.
