Configuration: Special functions: AUTOCAL deviation
You can use this dialog to define the conditions under which a
drift from the value of an AUTOCAL procedure 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 must not exceed this value (in this example: 6%,
see also section
(Page 122)), 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
acknowledged, the values a
re reset during the next AUTOCAL,
and counting commences at 1 again.
