Information on calibration
Calibration adapts the transmitter to the conductivity sensor.
Calibration can be performed by:
• Input of cell constant (e.g. for ultrapure-water sensors)
• Determining the cell constant using a known calibration
solution
• Sampling (product calibration)
• Temperature probe adjustment
Note:
• All calibration procedures must be performed by trained
personnel.
• Incorrectly set parameters may go unnoticed, but change
the measuring properties.
Exit Press cal to exit. The measured
value is shown in the main
display alternately with “Hold”,
“enter” blinks, Sensoface is
active. Press enter key to end
the Hold mode. The measured
value is dispålayed. The output
current remains frozen for
another 20 sec (HOLD icon on,
“hourglass” blinks).
