CALIBRATION
The probes are supplied factory-calibrated and usually don’t require additional user interven-
tion. Nevertheless a new calibration can be performed.
Note
: it is essential to know and respect the physical phenomena measurements are based on
in order to achieve correct calibration: it is recommended to perform new calibrations only if
you have the adequate technical expertise and to carefully follow the procedures described in
this manual.
To access probe calibration:
1.
Press
SELECT

Selecting a Pt100 or Pt1000 temperature-only probe for calibration displays four possibilities:
•
NEW TUNING
: calibrates the probe in one, two or three points. The possible calibration
points are 0 °C, one point ranging from 95 °C to 105 °C and one point ranging from
150 °C to 400 °C. The probe can be calibrated either in one point or in two points: for
the non-calibrated points, the instrument will use the values stored in the previous user-
