15. Dissolved Oxygen Setup
Use Setup Dissolved Oxygen mode to customize the parameter. Press
from the measurement screen and then press ENTER when DO% or DO (mg/L)
is selected for percent saturation or concentration modes respectively. Note that
setup parameters differ slightly depending on which is selected.
Sample ID
This is a user selectable number from 1 to 99999.
Incorporating a sample ID to identify one or more
data points is useful to distinguish data that is
saved into memory or sent to a PC or printer. Use
the up/down arrow keys to adjust the values and
left/right arrow keys to move the cursor.
Offset Cal (% saturation only)
Use this feature to offset the meter’s value to
another DO meter. Using the % saturation mode,
observe the reading a sample solution after it has
stabilized. Similarly, observe the reading of the
same sample using another DO meter as a
reference. The probe of the reference meter should
be immersed in the same sample at the same
depth.
The DO 2700 allows ±10% offset adjustment. Note that subsequent user
calibrations will reset the offset adjustment back to the factory default value of 0.0
% offset.
Pressure Unit (% saturation mode only)
Select mmHg or kPa pressure units.
