Measurement

Before lowering the sensor probe into the sample, do not connect the hook on the unit to
a human body.

The correct values are not displayed if the sensor is not mounted when the measurement
display is activated.

Perform DO measurement with no air bubbles in the internal solution.

Do not reuse a membrane cap of DO sensor.

Use the spanner for DO sensor provided to attach or remove the DO sensor.

Avoid both U-53 and U-53G turbidity measurement in air, since the rubber wiper will
quickly become damaged.

Attach sensor guard to sensor probe in the measurement. When sensor probe is used in
calibration cups (black and transparent) or flow cell, the sensor guard can be taken off.

Calibration
During atmosphere calibration for the DO electrode with DO salinity compensation set to
automatic, values are compensated based on electrical conductivity, but calibration is
performed normally.
