Data Output Format $Pvhy2 (Post November 2020) - Valeport Hyperion Chlorophyll a Operating Manual

6.2 Data Output Format $PVHY2 (Post November 2020)

The Hyperion outputs a single NMEA style data string – post November 2020 (Serial No: 75100)
this will be a $PVHY2 format string.
Example - Turbidity: $PVHY2,01,8,0.48705,0.012,NTU,141.65588,0.023,NTU,M1,*6D
Example – Fluorometer: $PVHY2,01,1,0.816,0.012,ug/l,,,,C02,*24
Please note that fields with no data e.g. 2
delimited, as above.

If the sampling that has been setup such that only one measurement is used to produce a reading
then no Standard Deviation is generated and the output becomes:
Turbidity - $PVHY2,01,8,0.48705,,NTU,1.65588,,NTU,M1,*6D
Fluorometer - $PVHY2,01,1,0.816,,ug/l,,,,C02,*24
Otherwise:
Turbidity - $PVHY2,01,8,0.48705,0.012,NTU,141.65588,0.023,NTU,M1,*6D
Fluorometer - $PVHY2,01,1,0.816,0.012,ug/l,,,,C02,*24
