fIrst Power on
The instrument will step through an initial configuration when powered on
for the first time. This will set the language, dissolved oxygen sensor type and
membrane type. Use the up or down arrow keys to highlight the appropriate
language, sensor and membrane, then press enter to confirm (figures 6). The
Sensor Type must be configured for the dissolved oxygen sensor installed on the
cable. Failure to do this may result in damage not covered under warranty. If an
incorrect option is selected, it may be changed in the System Setup menu.

After selecting a language, sensor and membrane, the Run screen will be
displayed. The next time the instrument is powered up, the Run screen will
display immediately after the splash screen. If the sensor type or membrane type
is changed, ensure that it is updated in the System Setup menu.

Press the menu key to access the System Setup menu. The System Setup
menu contains multiple screens that are notated as ‘pages’. The current page is
indicated near the bottom of the display (figure 7).
Use the up and down arrow keys to scroll through menu options and menu
pages.
EXITING THE SYSTEM SETUP MENU
To exit the System Setup menu, press the down arrow key until the ESC - Exit
box is highlighted, then press enter to return to the Run screen.
do local%
DO Local% can be enabled or disabled by using the up or down arrow keys to
highlight it and then pressing enter . An ‘X’ in the box next to Do Local%
indicates it is enabled (Figure 7).
Figure 7, page 1 of System Setup menu. DO Local% is enabled.
When Do Local% is enabled, Do% values will be expressed as %L on the Run
screen.
Do Local% allows for localized % saturation measurements, but does not
affect the mg/L readings. When enabled, the Do% calibration value is always
100% regardless of the altitude or barometric pressure of the location. This
deviates from YSI’s traditional method of expressing Do% saturation where
the % calibration value decreases with a decrease in barometric pressure, i.e. an
increase in altitude (Appendix A). To determine the % calibration value when
Do Local% is disabled, divide the local barometric pressure pressure in mmHg
by 760 and then multiply by 100.
Example: 750/760 = 0.9868 x 100 = 98.68% calibration value when Do Local is
disabled.
When Do Local% is enabled, the Pro2030 corrects for barometric pressure on
each Do measurement instead of during calibration.
