Page 7: Set Up
SET UP Polarization It will take 2-3 minutes for the probe to polarize. When the meter is first turned on very high oxygen readings will be displayed. However, these readings will drop to a steady state as oxygen that was absorbed in the electrolyte solution, while the meter was turned off, is reduced. -
Page 8: Measuring Dissolved Oxygen
The electrode membrane must be clean and dry or the calibration will be incorrect. Moisten the sponge in the electrode storage cap with distilled or tap water. The sponge should be moist but not soaked. Place the electrode storage cap on the meter. When the reading is stable, press and hold the CAL/RECALL button for 2 seconds until CAL appears on the display. -

Warm water and Clean with mild household detergent detergent solution. Rinse thoroughly with DI water. - Page 17 Remove a new membrane cap assembly from the red storage container. Do not touch the membrane part of the assembly as skin oils with interfere with the oxygen permeability rate of the membrane. Set the membrane cap assembly on a flat surface. Fill the membrane cap assembly with Electrolyte Solution (DO600-EL) to the bottom of the threads on the inside of the cap.
