4 CALIBRATION

4.1 Important Information on Meter Calibration

The amount of oxygen dissolved in water will depend on its temperature, atmospheric

pressure and its salinity. While the pressure and salinity values are manually entered

into the instrument, the temperature is being measured by the probe. It is therefore

very important that the temperature is calibrated if necessary prior to the DO

calibration.

The measurements of % Saturation of DO will linearly affect the measurement for DO

in mg/L. Hence calibration in % Saturation of DO should be carried out first. This is

described in the following section.

Before calibrating, press MODE key to select the correct measurement mode. There

are 2 measurement modes for DO: mg/L or ppm, and % Saturation.

NOTE: All new calibrations will automatically over-ride existing calibration values.
