Pro30
Quick Start Guide
Item #606083
This pocket guide serves as a quick reference in calibrating and operating the Pro30
conductivity and temperature instrument. It is not intended to replace the information
found in the User Manual.
Calibration
The Pro30’s temperature sensor cannot be calibrated nor should calibration be
required. If the temperature sensor is not reading accurately, contact YSI or your local
representative
The Pro30’s conductivity sensor can be calibrated in conductivity, specific conductance
or salinity measurement mode. Calibrating any option will automatically calibrate the
others. YSI recommends calibrating in specific conductance for both ease and accuracy.
The following steps outline the specific conductance calibration.
1. Fill a clean container (ie plastic cup or glass beaker) with fresh, traceable
conductivity calibration solution and place the sensor into the solution. The
solution must cover the holes of the conductivity sensor that are closest to the
cable. Ensure the entire conductivity sensor is submerged in the solution or the
instrument will read approximately half the expected value.
2. Gently agitate the probe to remove any air bubbles from the conductivity
sensor.
3. Press and hold the Cal key for a few seconds. Highlight Sp. Conductance and
press Enter.
4. Highlight the units you wish to calibrate, either uS/cm or mS/cm, and press
Enter. 1 mS = 1,000 uS.
5. Next, use the up or down arrow key to enter the conductivity value of the
solution as it is labeled for 25°C. (Specific conductance is temperature
compensated conductivity and the instrument uses the default reference
temperature of 25° when calibrating specific conductance.) Depressing either
the up or down arrow key for 5 seconds will move the changing digit one place
to the left. The Pro30 will remember the calibration value and display it the next
time a calibration is performed.
6. Press Enter to confirm the calibration value.
7. Wait for the readings to stabilize and then press Enter to complete the
calibration. Or, press Cal to cancel the calibration and return to the Run screen.

Viewing and Deleting Saved Data
To view saved data, highlight Data and press Enter. Use the up or down arrow key to
scroll through the saved data points. Press Enter to access the functions on the bottom
of the display. From there, you can highlight Erase and press Enter to delete data. Or,
highlight ESC and press Enter to return to the Run screen.
8. ‘Calibration Successful’ will display for a few seconds to indicate a successful
calibration and then the instrument will return to the Run screen.
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 Guide in the Users Manual for information on how to correct the
problem. Possible solutions may include cleaning the conductivity sensor, ensuring the
correct value of the calibration standard is entered, ensuring the sensor is completely
submerged in the solution and/or using a new solution.
Taking Measurements
1. Ensure the conductivity sensor is completely submerged in the sample. The two
holes near the cable should be covered by the sample for accurate conductivity
readings.
2. Highlight Save and press Enter to store the reading. The instrument will confirm
that the reading was successfully saved.
