10.6 Data Format
Data is returned to the RS232 Port by the 90-FL in the following format.
Please note that a “ • ” shown anywhere in this section denotes one space.
dd/mm/yyyy•hh:mm:ss•LLLL•DDDDDuuu•CCCCCCCuuu•PPPPPuu•TTTTTuuLaaaaA•bbbbB
where….
dd/mm/yyyy is the date, month and year data.
hh:mm:ss is the hours, minutes and seconds data.
LLLL is the Log Number, 4 characters, right justified. The 90-FL sends a Zero for
instant readings (see section 10.2).
DDDDD is Dissolved Oxygen data. 5 characters, right justified.
uuu is the Dissolved Oxygen units description, which can be any of the following…
ppm
for parts per Million readout without Salinity correction.
Note the lower case “m”.
ppM
for parts per Million readout with Salinity correction
applied. Note the upper case “M”.
%S•
for % Saturation readout.
%G•
for % Gaseous readout.
CCCCCCC is Conductivity or TDS data. 7 characters, right justified.
uuu is the Conductivity/TDS units description, which can be either of the following…
uS•
for µS/cm Conductivity readout.
All readings are converted to µS/cm to ensure that the
data is logical when analysed with other programs.
ppM
for parts per Million TDS readout.
All readings are converted to ppM to ensure that the data
is logical when analysed with other programs.
PPPPP is pH data. 5 characters, right justified.
uu is the pH unit description, sent as “pH”.
TTTTT is Temperature data, 5 characters, right justified.
uu is the Temperature unit description. Sent as “oC” for measured temperature data,
or “oM” for manual temperature data.
L is the Low Battery indicator. Sent as “L” when the battery is below 5.60 volts.
Caution : Data recorded with a low battery may be unreliable.
The 90-FL sends a space when the battery is above 5.60 volts.
