5.7 ‘Advanced’ Page
The advanced page contains functions that will change the how the microDAQ acts and how it
applies various calculations to its data, this page should only be used by users who fully
understand what they are changing.
5.7.1 Filtering
The microDAQ has settings to allow the user flexible control over the data throughput of the device.
Averaging options allow the preference of noise reduction over time domain response, the
frequency of calibration temperature compensation renewal may be chosen as may be the size of
the average (and hence time taken) for the rezero routine. Table 5.2 details the function of the
signal parameter option controls.

Control
Function
'Pressure Input Impulse Filter'
Check box to apply impulse filter to pre calibration data - will remove
single impulse noise events in the pressure data.
'Temperature Input Impulse Filter'
As above but with temperature data.
'Pressure input average samples'
Selects the number of samples for a moving average of pre calibration
pressure data.
'Temperature input average samples'
As above but with temperature data.
'Temperature Compensation'
Selects the temperature compensation scheme for the calibration.
'Continuous' repeatedly rebuilds the calibration data on a channel by
channel basis without interrupting the flow of data. 'With zero only'
rebuilds the table when a user rezero is issued, after the rezero has
been actioned.
‘Apply’
Applies the settings to the local settings memory

5.7.2 Advanced communication settings
The microDAQ has several more advanced communication options available, but these features
are unlikely to be used by an everyday user and as such should generally be left as default
settings.
