One-point and Two-point Calibrations
Though it is usually not necessary, a one-point or two-point cali-
bration can be performed on any of the measurements to make
them more accurate. To do so, you must have a very accurate,
independent means of measuring pressure such as a barometer.
For step-by-step instructions refer to the documentation for
DataStudio, the Xplorer, or the Xplorer GLX.
Over-sampling
The Dual Pressure Sensor uses dynamic variable over-sampling
to reduce noise, produce smoother data, and improve the mea-
surement resolution. This effect is especially noticeable when
very small pressure changes or differences are measured. The
degree of dynamic variable over-sampling that takes place within
the sensor depends on the sample rate. To maximize the
over-sampling, set the sample rate as low as possible for a given
application. Maximum over-sampling occurs at sample rates of
1 Hz or slower.
