D.O. concentration
It is possible to select: ppm or mg/l.
Conductivity and Actual Conductivity
It is possible to select: Auto (autoranging both
μS/cm and mS/cm),1 μS/cm, 0.001 mS/cm,
0.01 mS/cm, 0.1 mS/cm, 1 mS/cm, Auto mS

Ω
/cm, k
Ω
/cm or M
Ω
/cm.
TDS
It is possible to select: Auto, autoranging both
ppm(mg/l) and ppt(g/l),1 ppm (mg/l), 0.001 ppt
(g/l), 0.01 ppt (g/l), 0.1 ppt (g/l), 1 ppt (g/l),
Auto ppt (g/l) (autoranging in ppt or g/l unit).
NOTE: For setting ppm or mg/l, see paragraph
3.2 System Setup.
Seawater specific gravity
This value is a widely used parameter for seawater; it is similar to density mea-
surement and it is an expression of salts content in water.
It depends on atmo-
spheric pressure, temperature and salinity.
In the seawater specific gravity menu it is possible to select the reference tem-
perature:
σ
t
,
σ
0
, and
σ
15
. (Current temperature, t=0 °C, t=15 °C respectively).
Atmospheric pressure
It is possible to select: atm, kPA, mmHg, inHg,
mbar, psi.
NOTE: A maximum of 12 measurements can
