Hach sensION+ DO6 - 5 Set-Up; Atmospheric Pressure; Salinity

9
5. Set-up
The sensION ™+ DO 6
is supplied with the following
parameters:
– Atmospheric pressure: 1013 mb.
– Salinity: 0.0 g/L.
To display and/or modify these pa-
rameters, follow the diagram below.
5.1. Atmospheric pressure
Enter the atmospheric pressure value for the instrument to make the relevant compensation.
5.2. Salinity
Enter the salinity value of the sample to be measured. This is deter-
mined with a conductivity measurement.
Important note: salinity only affects the DO concentration
measurement (mg/L).
