2 Deactivation of the detecting unit can be done according to the procedure established at the object of
use for ionizing radiation measuring instruments.
3.1.3.2 Delivery kit completeness check
Check if the delivery kit of the detecting unit is complete according to 1.3. Check the technical
condition, the placement of the component parts of the detecting unit, and the presence of the
maintenance documentation.
3.1.3.3 Operability check of the detecting unit
3.1.3.3.1 Operability check of the detecting unit in the process of its use is performed
automatically. Operability check of the detecting unit during its long-term storage is performed
according to 2.2.4.
3.1.3.3.2 The procedure of pre-repair fault detection and rejection
Use the following criteria to evaluate the necessity of sending the detecting unit for repair and
type of repair:
- for mid-life repair:
а) deviation of parameters from control values during periodical verification of the detecting
unit;
b) minor defects of the cable or the connectors that do not affect their hermiticity and correct
readings of measurement results;
- for major repair:
a) at least one non-operating measuring channel;
b) mechanical damages that affected the hermiticity of the detecting unit case or the cable.
3.1.3.4 Refreshment of damaged painting
Refresh damaged painting of the detecting unit case with the help of the
НЦ-1125 enamel. Thoroughly select the color tone to avoid a considerable difference of lacquer
coating. Remove contamination from the segment that needs painting. Brush on a level layer of paint
on the surface.
3.1.3.5 Registration of operations in the performance records table.
Register actual operation hours of the detecting unit in section 11 of the logbook.
