Page 2: Probe Preparation
Milwaukee Instruments Instruction Manual www.eseasongear.com PROBE PREPARATION: The meter is supplied with a 9V battery. Slide off the battery compartment cover on the back of the meter. Install the battery into the battery clip connector while observing polarity. D.O. probes are shipped dry. Assemble the probe and prepare it for use, connect it to the meter and proceed as follows. -
Page 3: Calibration Procedure
Milwaukee Instruments Instruction Manual www.eseasongear.com PROBE POLARIZATION: • A dissolved oxygen probe must be polarized to function properly. • To polarize the probe, the fully assambled probe must be connected to the meter and the meter must be on. • During polarization (and during measurement), approximately 800 mV is applied to the cathode and anode inside the membrane and a chemical reaction occurs. - Page 4 Milwaukee Instruments Instruction Manual www.eseasongear.com Zero Calibration: • Dip the probe into MA9070 zero oxygen solution and stir gently for 2-3 minutes. • Wait for the probe to reach it’s lowest stable reading. • Adjust the zero D.O. calibration trimmer (located on the front panel) until the display reads "0.0".

Page 5: Taking Measurements
Milwaukee Instruments Instruction Manual www.eseasongear.com TAKING MEASUREMENTS: Verify the probe is polarized and the probe and meter have been calibrated. Remove the protective cap from probe. Immerse the tip of the probe in the sample to be tested. For accurate dissolved oxygen measurements a minimum water movement of 0.3 m/sec is required. -
Page 6: Altitude Compensation
Milwaukee Instruments Instruction Manual www.eseasongear.com ALTITUDE COMPENSATION: The displayed measurements are referenced to sea level pressures. At higher elevations, oxygen solubility decreases (thus at higher elevations actual oxygen concentrations are really lower than the displayed value). The table below illustrates the changes in the solubility of oxygen in air saturated fresh water as a result of changes in elevation. -
Page 7: Salinity Compensation
Milwaukee Instruments Instruction Manual www.eseasongear.com SALINITY COMPENSATION: The table below illustrates the change in the solubility of oxygen in air saturated water as a result of chloride concentration or salinity. The table can also be used to correct the displayed measurement. - Page 8 Milwaukee Instruments Instruction Manual www.eseasongear.com For example, if the measurement displayed at 10°C is 5 ppm, but the sample has 20 g/L of chloride, to correct your measurement multiply the displayed measurement by the ratio of (ppm reading at 20 g/L) / (ppm reading at 0 g/L) = 5.0 ppm X (8.9 ppm/11.3 ppm) = 3.93 ppm (or 3.9 ppm Chloride or Salinity corrected).
- Page 9 Milwaukee Instruments Instruction Manual www.eseasongear.com The Platinum cathode should always be bright and untarnished. If it is tarnished or stained, due to contact with certain gases or a damaged membrane cap, the cathode should be cleaned. You can use a clean lint-free cardboard or cloth.
