User-settable constants

Table 1‑1. User-settable constants available in BiometConstants.
Field Value (default) Description
BiometPackage 100 Sensor package identifier (100, 101, 102, or 103).
AveragePeriod 60 Time period over which to average sensor data in seconds.
ScanInterval 5 How often to sample the sensors in seconds. Note that the HydraProbes require a 3-second warm up before each sampling event.
UsePublicVars 0 Flag to set raw variables as public or not: 1 = public, 0 = not public
LogBiomet
Data		 9999 Number of records to keep in Biomet data table.
