The alternative way is to define and fix the tolerance values for both voltages
and currents to some user preferred value. This option is called Fixed Quality
since in that case the data will be stored at the same tolerance/quality at all times.
When Fixed Quality mode is selected, you are requested to define the tolerance
value for voltages and currents separately were the factory default value is 0.1%.
File Capacity
The File Capacity parameter is used to define the maximum time each PQZip
file will comprise. The file can be downloaded and data can be analyzed only
when the file is closed, so if you expect to monitor the data on the Investigator
application shortly after the data is being collected, you should choose low time
durations. For all other cases, longer durations are recommended so compression
ratios can be slightly improved.
Record Mode
The Record Mode parameter defines whether PQZip files will comprise FULL
data or event time stamps only (LIGHT mode). The default setting is FULL.
