Dissolved Oxygen ( DO ) measurement
procedures

Power on, after calibration procedures be executed.

Slide the " DO/O2 selector " to " DO " position. 

Determine the " % Salt " & " Height " values.

 * For the general application, it is not necessary to make

the adjustment for the " % salt " & " Height " values. 

Immerse the probe head into the measured liquid.
