7. If the calibration is unsuccessful, an error message will display
on the screen. Press the Cal key to exit the calibration error
message and return to the Run screen. See the Troubleshooting
section of this manual for possible solutions.
CALIBRATING IN SALINITY
1. Place the sensor into the solution. The solution must cover the
holes of the conductivity sensor that are closest to the cable
(figure 8). Ensure the entire conductivity sensor is submerged
in the solution or the instrument will read approximately half
the expected value. Gently move the probe up and down to
remove any air bubbles from the conductivity sensor.
2. Turn the instrument on and allow the conductivity and
temperature readings to stabilize. Press and hold the Cal key
for 3 seconds. Highlight Conductivity and press enter. Next,
highlight Salinity and press enter.
3. Use the up or down arrow key to adjust the value on the
display to match the value of the salinity solution. Press and
holding either the up or down arrow key for 5 seconds will
move the changing digit one place to the left. The Pro1030 will
remember the entered calibration value and display it the next
time a salinity calibration is performed.
4. Press enter to complete the calibration. or, press Cal to cancel
the calibration and return to the Run screen.
5. ‘Calibration Successful’ will display for a few seconds to indicate
a successful calibration and then the instrument will return to
the Run screen.
6. If the calibration is unsuccessful, an error message will display
on the screen. Press the Cal key to exit the calibration error
message and return to the Run screen. See the Troubleshooting
section of this manual for possible solutions.

Before taking measurements, be sure the instrument has been
calibrated to ensure the most accurate readings. Install the sensor
guard to protect the pH or oRP sensor. Place the probe in the sample
to be measured and give the probe a quick shake to release any air
bubbles.
condUctIvIty
The conductivity sensor will provide quick readings as long as the
entire sensor is submerged and no air bubbles are trapped in the
sensor area. Immerse the probe into the sample so the sensors are
completely submerged and then shake the probe to release any air
bubbles. occasional cleaning of the sensor may be necessary to
maintain accuracy and increase the responsiveness. To clean the
sensor, use the soft bristle cleaning brush provided with the instrument
and a mild detergent.
ph/orp
pH and oRP readings are typically quick and accurate. However, it may
take the sensors a little longer to stabilize if they become coated or
fouled. To improve the response time of a sensor, follow the cleaning
steps in the Maintenance section of this manual.

The Pro1030 can store 50 data sets in non-volatile memory for later
viewing. A data set includes the values currently on the display, i.e.
temperature, dissolved oxygen and two conductivity parameters. Each
data point is referenced with a data set number, 01 through 50.
savIng data
From the Run screen, use the up or down arrow keys to highlight the
Save box and press enter to save the current readings. The instrument
will indicate the data set is saved and display the saved data set’s
number (figure 9).
