Operating and functions
9.12.4. Calibrating the sensor
DANGER
Risk of injury due to electrical voltage
• Observe all applicable accident protection and safety guidelines for electrical equipment.
Risk of injury due to the nature of the fluid.
• Respect the regulations on accident prevention and safety relating to the use of aggressive fluids.
See chap. 9.9 to access the Calibration menu.
Choose the type of probe (see chap. 9.11.11) the transmitter is fitted with before calibrating the sensor.

CALIB TEMPERAT.: choose the type of temperature compensation for the calibration process: either the tem-
perature measured (select "Auto") or a fixed value (select "constant" then enter reference temperature).
→ Calibrate the sensor using one of the following methods:
- CALIBRATION: calibrate the pH sensor in 1 or 2 points or the Redox sensor in 1 point. See details on fol-
lowing pages. A calibration process updates the last calibration date ("Last cal. date" function of the CALIB
INTERVAL sub-menu hereafter).
- PROBE CONSTANTS: enter the offset and/or span values indicated on the pH / Redox sensor certificate, if
supplied. This input replaces a calibration made by the "Calibration" function above but does not update the
last calibration date ("Last cal. date" function of the CALIB INTERVAL sub-menu hereafter).
CALIB INTERVAL: read the date of the last calibration (function "Last cal. date") and set the periodicity of cali-
brations, in days (function "Interval"): the transmitter generates a "maintenance" event by displaying the
icon
and a "warning" event, each time a calibration is due. Set function "Interval" to "0000 days" to ignore the function.
• The "warning" event may be associated with one or other or both transistor outputs (see chap. 9.11.10).
• See also "If you encounter problems" at chap. 10.5
Calibrate the pH / Redox sensor ("Calibration" function in the "Probe" menu)
• The pH sensor can be calibrated according to a 1-point or a 2-point procedure.
• The Redox sensor can be calibrated according to a 1-point procedure.
