the 3-point procedure.
For all rhodamine calibration procedures, be certain that the standard and sensor are thermally equilibrated
prior to proceeding with the calibration.
REESTABILISHING DEFAULT CALIBRATION – “UNCAL” COMMAND
If, for any reason, you want to return to the factory default settings (slope and offset) for any parameter,
follow the instructions below:
 Activate any calibration screen (1-point, 2-point, or 3-point) where a numerical entry is requested. In
the example below, a 2-point turbidity calibration was selected.
 Instead of entering a numeric value, type the word “uncal” and press
Enter
.
 An “uncal” entry at any calibration prompt will reset both slope and offset for this parameter to the
factory default settings.
NOTE:
When using the 650 MDS as the sonde interface device, the “uncal” operation is performed by
holding the Enter key down and then pressing the Esc key. See Section 3 of this manual for more details.
