taking into account the lower degree of oxy-
gen solubility in such conditions (see "Alti-
tude Compensation" and "Salinity Compen-
sation" sections for details).
Remember to set altitude and/or salinity be-
fore taking ppm measurements, and the meter
will automatically compensate for these fac-
tors.
TEMPERATURE READINGS
The supplied probe is provided with a built-in
temperature sensor.
Press the FUNCTION key to display the
measured temperature.
Allow the probe to reach the thermal equilib-
rium before taking any measurement. This
can take several minutes. The greater the
difference between the temperature at which
the probe was stored and the temperature of
the sample, the longer the time will be.
If the display shows "°C ---.-", the D.O. probe
is not properly connected. This can also indi-
cate a broken probe cable.
