1 - 4 Requirements
The following values measured in the factory are documented in the test report:
- Brightness of the light localizer
- Visual test of filter values
- Coincidence of light field and radiation field
- Accuracy of the X-ray tube voltage
- Checking the mAs values
- Reproducibility of radiation
Notes on the protective conductor resistance test 1
Observe the instructions in the safety rules for installation and repair
(ARTD-002.731.17 ...).
The protective conductor resistance of 0.2 ohms must not be exceeded.
Initial measurement
Perform the protective conductor test after completion of all work.
The measurement must be made according to DIN VDE 0751, Part 1 (see ARTD Part 2).
In this case the protective conductor resistance in the normal operating condition to all
conductive touchable parts of the system must be measured.
Make sure that control cables or data cables between the components of the system do
not imitate any protective conductor connection.
During the measurement, move the power cable and additional connection cables with
integrated protective conductor section by section to detect cable breaks.
The protective conductor resistance must not exceed 0.2 Ohms.
The values must be recorded as initial measurements in the report ’Protective conductor
resistance / report’ stating the measuring points.
Document the measuring procedure and the measuring instrument used (designation
and serial number).
