Atmospheric pressure compensation (DO)
Differences in the atmospheric pressure of the measurement location influence the Dissolved
Oxygen (DO) measurement. By setting (input) the actual atmospheric pressure of the
measurement location into the control unit, it is possible to standardize the measured
Dissolved Oxygen (DO) value to a value at the standard atmospheric pressure (1013 hPa).
Reference
“ 6.4.4 Atmospheric pressure compensation (DO) - Relation of altitude and air pressure ” (page 107)
Note
If air bubble in the internal solution is large, change the internal solution.
Calibrate at the place of same atmospheric pressure before the measurement.
1.
Press the control unit’s POWER key for about 1 second to turn the power ON.
The "MEASUREMENT" screen appears after about 10 seconds.
Note
The operation keys are designed to operate using the pad of a finger, sharp objects can tear the
