The following calibrations are possible:
• Calibration
• In-situ calibration with the certified solid state reference
• Recalibration by the manufacturer
• Application adjustment
• Calibration or adjustment using reference samples via a value table (1-6 points)
• Entry of a factor (multiplication of the measured values by a constant factor)
• Entry of an offset (addition/subtraction of a constant value to/from the measured
values)
‣
Before a calibration, clean the device so that there is no dirt on the optical window.
Solid state reference
The sensor is adjusted ex-works in compliance with Resolution MEPC.259(68) and
MEPC.340(77).
1. To comply with the MEPC.259(68) and MEPC.340(77) criteria, calibrate the sensor
at least once a year using the solid state reference.
2. If necessary, adjust the sensor with the solid state reference.
The solid state reference is qualified for calibration and adjustment in the entire sensor
measuring range according to the requirements of the relevant MEPC resolutions.
We recommend you send in the sensor and solid state reference to the manufacturer every
4 years for inspection and recalibration.
During factory calibration, the solid state reference is adapted to the sensor. The solid state
reference can only be used with this sensor. The solid state reference and the sensor are
therefore permanently assigned to one another.
The functional integrity of the sensor can be checked using the solid state reference. The
sensor can be calibrated and adjusted. Adjustment is performed automatically by the
transmitter following calibration.

CAUTION
High pressure and high temperatures when removing the sensor
Risk of injury!
‣
Pay attention to the process pressure and process temperature.
‣
If the process pressure is elevated, reduce the process pressure before removing the
sensor. Use the manual valve mounted onsite for this purpose.
