These parameters are
intended for customer-
specific adaptation.
Alteration to the settings
may only be carried on the
express instruction of the
equipment manufacturer.
Parameter Value/Selection Description
Calibration status Configuration
➔ Fine calibration
➔ Analog input 1 — 6
➔ Calibration status
Off,
On A calibration (adjustment)
of the analog
measurements can be
activated here. The
adjustment is carried out
using a linear equation.
Actual start value Configuration
➔ Fine calibration
➔ Analog input 1 — 6
➔ Actual start value
-99999 to 0 to +99999 Start value for
actual line.
Only active when
calibration status = On.
Set start value Configuration
➔ Fine calibration
➔ Analog input 1 — 6
➔ Set start value
-99999 to 0 to +99999 Start value for
target line.
Only active when
calibration status = On.
Actual end value Configuration
➔ Fine calibration
➔ Analog input 1 — 6
➔ Actual end value
-99999 to 1000 to +99999 End value for
actual line.
Only active when
calibration status = On.
Set end value Configuration
➔ Fine calibration
➔ Analog input 1 — 6
➔ Set end value
-99999 to 1000 to +99999 End value for
target line.
Only active when
calibration status = On.
H
Systematic errors, such as those caused by an unsuitable probe
mounting, for example, can be compensated through fine
calibration.
Example:
A sensor covers temperatures from 200 to 300°C.
It is built into a tunnel oven so unfavorably that it always indicates
10°C less than the temperature of the oven contents. The incorrect
measurement can be corrected through fine calibration.
Actual start value : 200°C
Set start value : 210°C
Actual end value : 300°C
Set end value : 310°C
