Laboratory and Field Calibration Section 4
Use the arrow keys to highlight the output line for specific conductance as shown above. Press
Enter and the following display will be shown.
Using this display, you will now be required to input the ACTUAL value of your conductivity
standard. First use the right and left keyboard arrow keys to highlight the digits of the display
which your wish to vary. Then use the up and down keyboard arrows to increment this digit the
higher or lower values, respectively, until the desired value is shown. Proceed to additional digits
and make variations as required. When the displayed value is correct, press the Enter key and the
following screen will be shown.
This display allows you to view in REAL TIME the actual specific conductance values from your
probe. At this point you also have the option of aborting the calibration completely to return to
the Run display by highlighting the Abort selection and pressing Enter. If you inadvertently
entered the wrong value for your standard, highlight Redo and press Enter. You may reenter your
numerical calibration value at this point.
If you have made no mistakes in value entry, make certain that the Cal selection is highlighted,
watch the readings in real time and when they are stable for approximately 30 seconds, press the
Enter key to confirm the calibration. The following screen will appear indicating that your
calibration was successful.
