Item #605057

This Quick Start Guide is meant to serve as a quick reference in calibrating and 
operating the Pro2030. It is not intended to replace the information found in the Users 
Manual.

Setting Dissolved Oxygen Sensor & Membrane Type

The instrument’s dissolved oxygen (DO) sensor type must be configured for the sensor 
installed. Failure to do this may result in damage not covered under warranty. The 
correct DO membrane type must be configure for the membrane in use or the DO 
readings will be erroneous.  

The instrument will step you through an initial configuration when powered on for the 
first time. This allows you to set the language, sensor and membrane options. Use the 
up or down arrow keys to highlight the appropriate language, sensor, and membrane, 
then press enter to confirm. Check the label on the box of the sensor and membrane 
to determine which option you have. To change the sensor or membrane type after the 
initial configuration, press the
