resettIng the systeM setuP Menu
to factory default
To reset the Pro2030 settings to factory default, press the down arrow key while
in the System Setup menu until the Reset - box is highlighted, then press
enter. The instrument will ask you to confirm the reset. Highlight Yes and press
enter to continue with the reset or highlight No and press enter to cancel the
reset. A Factory Reset will not affect data saved in the instrument’s memory.
The following will be set in the Pro2030 after performing a reset:
Parameter Reset Defaults
Do Local% off
LDS (Last Digit Suppression) off
Quick Do Cal off
Audio on
Contrast Set to mid range
Dissolved oxygen Sensor Type Last Setting Confirmed
Dissolved oxygen Membrane Type Last Setting Confirmed
Dissolved oxygen Auto Stable off (0.0 % Change and 10 seconds)
Dissolved oxygen Units mg/L and %
Conductivity Units cond mS/cm and spc mS/cm
Conductivity Auto Stable off (0.0 % Change and 10 seconds)
SPC Reference Temperature 25°C
SPC Temperature Coefficient 1.91%/°C
TDS Constant 0.65
Temperature Units °C
Pressure Units mmHg
Language English
Auto Shutoff 30 minutes
Dissolved oxygen Calibration Reset to 100% for enabled
membrane and sensor.
Conductivity Calibration Cell constant reset to 5.0
Barometer Calibration Reset to factory default*
*It is recommended to perform a barometer and dissolved oxygen calibration
after performing a reset.

teMPerature
All Pro2030 cables have built-in temperature sensors. Temperature calibration is
not required nor is it available.
BaroMeter
The barometer in the Pro2030 is calibrated at the factory. The barometer reading
must be accurate to ensure accurate Do% calibrations and readings. If the
barometer requires an adjustment, use the up or down arrow keys to highlight
the barometer box along the bottom of the Run screen, then press enter. Next,
use the up or down arrow keys to adjust the barometer reading to the local, true
barometric pressure. Continually depress the up or down arrow key to change
the barometer value more rapidly. Press enter to confirm and save the barometer
adjustment.
Although the Pro2030 barometer range is 400.0 to 999.9 mmHg, you will be
unable to adjust the value across the entire range. The barometer is very accurate
and the instrument will not allow you to adjust the value drastically beyond what
it is measuring.
dIssolved oxygen
The dissolved oxygen sensor can be easily calibrated with the press of two or
three keys by enabling Quick Do Cal in the System Setup menu and following
the Quick Do Calibration procedure.
Ensure the barometer is reading accurately before performing a Quick Do Cal,
Do% or Do Local% calibration because these calibration procedures use the
barometer reading during calibration. If the barometer reading is erroneous
during a calibration, the dissolved oxygen measurements will be inaccurate.
Do not use a barometer value that is corrected to sea level. Laboratory
barometer readings are usually “true” (uncorrected) values of air
pressure and can be used “as is” for barometer calibration. Weather
service readings are usually not “true”, i.e., they are corrected to sea
level, and therefore cannot be used until they are “uncorrected”. An
approximate formula for this “uncorrection” is:
True BP = [Corrected BP] – [2.5 * (Local Altitude in ft above sea level/100)]
