DISSOLVED OXYGEN OPERATION

The XL600 meter measures DO (Dissolved Oxygen), BOD (Biological Oxygen Demand), OUR (Oxygen
Uptake Rate) and SOUR (Specific Oxygen Uptake Rate). Each mode is independent and has separate
Setup screens for each mode. For best results, perform standardization daily.
• In DO Setup, select the desired measurement unit. In OUR and SOUR setup modes, the measurement
unit cannot be changed.
• In DO Setup, select the Calibration mode options:
% Saturation Calibration Mode Options:
Auto calibration at one point (100 % saturation)
Auto calibration at two points (0 and 100 % saturation)
Manual calibration at one point
mg/L Calibration Mode Options:
Auto calibration at one point (8.26 mg/L)
Auto calibration at two points (0 and 8.26 mg/L)
Manual calibration at one point
mbar Calibration Mode Options:
None (measurement is applied from % saturation standardization)
