7.1 8.5.6 Period of unattended operation
The maintenance interval shall be at least 2 weeks.
7.2 Equipment
Not applicable here.
7.3 Testing
For this criterion, the tasks necessary to ensure proper functioning of the measuring system
as well as the corresponding interval were identified. In determining the maintenance inter-
val, the results of the drift tests at zero and span point according to 7.1 8.5.4 Long-term
drift were taken into account.
7.4 Evaluation
No excessive drift behaviour was observed during the entire period of the field test. The
maintenance interval is therefore subject to the necessary maintenance tasks.
During operation, maintenance tasks may primarily be limited to contamination and plausibil-
ity checks as well as potential status signals and error warnings.
7.5 Assessment
The maintenance interval is subject to the necessary maintenance tasks and is 4 weeks.
Does this comply with the performance criterion? yes
7.6 Detailed presentation of test results
Not applicable in this instance.
