Acquisition Mode the TRAX controls the data rate while in Polled Mode the TRAX
Studio program controls the data rate. Polled Mode is the default.
Sample Delay
The Sample Delay is relevant when Continuous Mode is selected. It is the time
delay, in seconds, between completion of TRAX sending one set of data and the start
of sending the next sample set. If the delay is set to 0, then TRAX will begin sending
new data as soon as the previous data set has been sent. Note that the inverse of the
Sample Delay is greater than the sample rate, since the Sample Delay does not
include the actual measurement acquisition time. The default is 0.
Polling Delay
The Polling Delay is relevant when Polled Mode is selected. It represents the time
delay, in seconds, between the completion of TRAX Studio receiving one set of
sampled data and requesting the next sample set. If the delay is set to 0, then TRAX
Studio requests new data as soon as the previous request is fulfilled. Note that the
inverse of the Polling Delay is greater than the sample rate, since the Polling Delay
does not include the actual measurement acquisition time. The default is 0.
6.5 Calibration and the Calibration Tab
As discussed in Section 5, a user calibration should be performed to optimize TRAX
performance. The Calibration Tab is shown below, and following this are discussions of how
to set the calibration settings, how to perform a calibration, and how to interpret the results.
