4.2 Calibration procedure for oxygen
4.2.1 Zero calibration
Zero calibration is not required for the oxygen version of the
Polytron 5000.
4.2.2 Span calibration
z The span calibration of an oxygen sensor requires oxygen
calibration gas or ambient air. Normally a cylinder
containing 20.9
% O
2
is used to match the atmospheric
concentration.
1. Fit the calibration adapter tightly to the end of the sensor if
calibrating with a cylinder containing oxygen. Alternatively,
if you want to calibrate the span using ambient air, leave
the adapter off and skip the next two steps.
2. Attach the pressure regulator to the calibration gas cylinder
containing 20.9
% O
2
.
3. Turn the gas flow on.
4. Scroll through software menu to Span Adj.
5. Wait for the signal to stabilize.
6. Trim the stabilized value to the calibration gas
concentration (normally 20.9
%) using the Up and Down
arrows.
7. Accept the value by tapping OK with the magnetic wand.
8. Turn off the gas flow and remove the calibration adapter
from the sensor.
