Example 1:

With pressure compensation factor set to 0.00 and the vent needle valve

fully open:

Oxygen: 100.01 Pressure: 122210

With pressure compensation factor set to 0.00 and the vent needle valve

not fully open:

Oxygen: 101.15 Pressure: 123554

New Pressure compensation factor:

1.14/1.10 = 1.04

8. Input the New Pressure Compensation Factor calculated from

your test data.

 Press the System key



Select the ‘PressureAdj’ function



Press the Enter key



Adjust the value with Up/Down arrow keys to value you calculated

(In Eample 1 above, the New Pressure Compensation Factor would

be set to ‘1.04’)



Press the Enter key.

The compensation is now set. The factor can still be tuned further, by

repeating steps 5 through 8. The pressure compensation factor entered at

the end of step 8 is now your starting factor. On the second, and further

iterations, you will find less and less change in the O

reading. A change

of 0.02 % O

or less would be acceptable. If it is more than that, go back
