3. GETTING STARTED

3.1. Connectors

1. Review the layout and arrangement of the rear connector panel.

2. Connect the power adapter’s output power jack to the meter’s

rear panel DC input power socket and plug in the adapter to a

power source.

4. USING THE METER

4.1. The Electrode

This meter comes equipped with a self-stirring BOD probe, model

5010, from YSI. Read the accompanying manual prior to installation

and operation. The 5010 probe need be plugged into the meter only,

as the meter supplies both its operation power and stirring power.

1. Prepare the electrode as described in its instruction manual.

2. Plug the electrode into the DO socket located at the rear panel of

the meter.

3. Place the probe into a BOD bottle filled with at least 1 inch of

water. Allow the probe to warm up for 30 minutes before

calibration or taking a measurement.
