Number Description
1 BAT: Low battery indicator.
2 Continuous or Manual sampling mode indicator.
When in Manual mode, manual will blink until the
measurement is stable.
3 CAL: Calibration mode indicator.
4 Data record indicator.
5 Temperature reading in Celsius.
6 mbar: Displays during calibration to prompt user for
true barometric pressure.
7 Main display for dissolved oxygen measurements in
either % or mg/L.
8 Save, Full, Recall, Each, All, Delete: Instrument’s data
storage indicators.
9 SAL ppt: Displays during calibration when user is
prompted for the approximate salinity (in ppt) of the
sample to be tested.

Press to turn the unit on or off. When turned on, the instrument will
perform a self-diagnostic test during which an error message may
display. This is normal. After the self-diagnostic test completes, the
temperature displays in the lower right and the dissolved oxygen
measurement displays in the center of the display (figure 6). The unit is
ready for operation. If necessary, perform a 1-point dissolved oxygen
calibration. The digital instrument and probe can hold its calibration
for many months but should be verified regularly.
Immerse the probe into the sample solution to take a measurement.
When the unit is not in use, turn it off to save battery life. It is not
necessary to recalibrate the instrument after turning it off and back on.
The instrument has a 30 minute auto shut off feature when not in use.
