Figure 33: Rate Control Screen
The
Operating Mode
radio buttons select the rate at which data are acquired. It is
recommended to set the data acquisition rate between 1 Hz and 10 Hz. All data
sampled are written into the data file and plotted on the time chart. Longer
averaging periods (or equivalently, slower data acquisition rates) yield better
measurement precision than shorter averaging periods.
Use the Plot every Nth fit radio button to automatically set the rate at which the
data are updated on the Main panel display. For example, if you set the value to 5, a
data point will be saved every 5 seconds.
