If the reading is out of range, the full-scale value
(400.0%) will be displayed blinking.
If this occurs during a log, a “!“ will be placed next to
the measurement unit. Data found in the CSV les
with a “!“ should not be considered reliable.
Natural Sea Water Scale
The Natural Sea Water Scale extends from 0 - 80.0 g/L. It determines salinity
based upon a conductivity ratio of sample to “standard seawater” at 15 °C.
Where R

is the conductivity ratio and salinity is dened by the following
equation:
S = - 0.08996 + 28.2929729R

+ 12.80832R

Note: The formula can be applied for temperatures
between 10 ºC and 31 ºC.
If the reading is out of the measurement range, the display will ash the highest
value possible and a warning message will be displayed. If this occurs during a
log a “!” will be placed next to the measurement unit. Data found in the CSV le
