Siemens ULTRAMAT 23 Series - Configuration: Special Functions: AUTOCAL Deviation (Only for IR Components)

8.4.2.2 Con󹪝guration: Special functions: AUTOCAL deviation (only for IR components)

Preset AUTOCAL drift
Quantity: 4
Limit : 6 %
You can use this dialog to de󹪝ne the conditions under which a
drift from a reference value of a previous AUTOCAL triggers a
maintenance request. The adjustable parameters are:
• Quantity:
The number of AUTOCAL procedures up to setting of a new
reference value (in this example: 4),
• Limit:
The largest possible value in % of the set measuring range. In
the case of autoranging, range 1 is assumed with max. 99% of
the full-scale value. The deviation from the last AUTOCAL ref‐
erence value must not exceed this value (in this example: 6%,
seeCalibration: AUTOCAL/drift values (Page 125)), otherwise
a maintenance request is triggered.

Number of AUTOCAL procedures until a reference is set again (set
number: 4)
The previous deviation is still displayed with the 4th AUTOCAL; at
the same time the value of the 4th AUTOCAL is used as the new
reference value.
If a maintenance request 'AUTOCAL deviation too large' is ac‐
knowledged, the values are reset during the next AUTOCAL, and
counting commences at 1 again.
The following parameters are set at the factory:
• Number of AUTOCAL procedures up to setting of a new reference value: 10
• Maximum deviation until a maintenance request is triggered 6%
• Maximum deviation until an error is triggered: 10%
Note
This function only applies to IR components.
