A.4 Programmable Pressure Compensation
Adjustment
The standard model 3010MA software includes pressure
compensation of the sensor in a 1 to 1 relation with atmospheric pressure
change. While this is adequate for most applications, sometimes small
errors in the O
2
reading are observed when pressure compensation is
slightly off. The latest version of the 3010M software provides a pressure
compensation factor to allow the user to fine tune compensation.
PROCEDURE:
By default, the 3010M’s uses a 1:1 compensation ratio. That is, if
the atmospheric pressure increases by 1%, the software will reduce the O
2
reading by 1%. To find the optimum pressure compensation factor, the
analyzer should be set up as follows and the procedure followed carefully.
1. Verify the pressure compensation factor is set to 1.00.
 While the analyzer is in the Analyze mode
 Press the System key
 Find and select the ‘PressureAdj’ function
 Press the Enter key
 Verify that the compensation factor is set to 1.00, adjust if
required
 Press the Escape key
