key to turn the unit on or off. The instrument will perform
a self-diagnostic test, during which an “ovEr” message may appear on the
display. This is normal. After the warm up is complete the message will
disappear. After the self-diagnostic test completes, the temperature
displays in the lower right of the display, and the unit is ready for operation.
Immerse the probe halfway into the sample solution. If possible, do not
allow probe to touch any solid object in the solution. Allow no air bubbles
around the probe. When the unit is not in use, turn it off to save battery life.
The instrument has a 30 minute auto shut off feature when not in use.
Note:
During an oxygen measurement, the probe must be
moved approximately 1/2 ft per second to overcome the inherent
consumption of oxygen by the sensor. When using the 200-BOD
lab probe, however, simply use the probe’s self-stirring feature.
Measurement Modes - % or mg/L
This unit provides three distinct measurements: Temperature, Dissolved
Oxygen in % saturation, and Dissolved Oxygen in mg/L (ppm). The
dissolved oxygen measurement unit is indicated on the right side of the
display. Press Mode to switch between % and mg/L.
