.2.1 It is recommended quarterly to carry out routine inspection in field. For this purpose:
age off;
to delete from a case a dust;
to test a condition of a case; to be convinced of absence of mechanical failures; to test a con-

oltage and input signal on the transducer after the termination of survey on.
If th release of a latch by
a screwdriver inserted into a recess in the bottom of the case.
3.3 Metrology monitoring
3.3.1 To confirm real values of the metrology characteristics and fitness of the transducer to
application, they can be exposed to calibration according to the document 49501860.3.0005 МП
« Преобразователи измерительные Е 855 А , Е 855 В , Е 855 С , Е 854 А , Е 854 В , Е 854 С . Методика
