Data Quality Control
The QML201 Logger has a 32-bit CPU, a 16-bit A/D conversion, and
advanced software with data quality control features in order to ensure
the continuous accuracy of the measured and calculated data.
Auto-calibration
The MAWS software automatically performs the offset recalibration
of the A/D converter and electronics every 15 minutes. In addition, the
self-calibration will be initiated automatically whenever there is a
temperature change of more than 1° C measured onboard the CPU.
The full ADC calibration will be made every 10th calibration time, i.e.
at least every 150-min.
Climatological/Measurement Limits
Check
The built-in quality control software checks the measured sensor data
against the user-set minimum and maximum limit values and step
changes between two successive measurements. The user can set these
data validation parameters independently for each measured parameter
and each site. There is also built-in test software to ensure the
reliability of the sensors’ measurements.
