SECTION 7,
continued
17.
If sample salinity
has been measured using
an Electrolytic
Conductivity Meter,
enter the value in
setup 4.
18.
Insert the probe
into the sample. The
probe must be deep
enough to cover the
thermistor (metallic
button) located on the
side of the probe.
19.
Agitate the probe
in the sample to dislodge
air bubbles from the
sensing area of the
probe tip.
20.
Stir the sample
vigorously with the
probe or use a stir stand
and stir bar. When
measuring deep bodies
of water, create
sufficient flow across the
probe tip by pulling on
the cable to move the
probe up and down.
21.
When the reading
on the meter stabilizes,
record or store the value
in the meter memory.
22.
Press the CONC %
key on the keypad to
change the display from
concentration in mg/L to
% saturation.
Note: The displayed %
saturation will be based on
a meter calculation for the
equilibrium dissolved
oxygen concentration. The
calculation uses the
sample temperature,
salinity, barometric
pressure, altitude and
measured concentration in
mg/L values. Changing
the entries in setups 4, 5
or 6 will alter the displayed
mg/L or % saturation.
