Remote Exposure Switch System (Optional); Dap Measuring System (Optional); Test Of Kv-Accuracy - Siemens MOBILETT Plus HP Installation And Setting Instructions Manual

Installation and setting

Remote exposure switch system (optional)

•
Check the function of the remote exposure switch system according to chapter functional
check of "Installation Instructions: Installation of remote exposure switch system".

DAP measuring system (optional)

•
Check the function of the DAP system according to section "Monthly checks" of the
Instructions for use.

Test of kV-accuracy

Requirement:
- The measured kV values, shall be within the limits.
Required measurement devices:
- kV-meter, based on the filter-comparison method, for example PTW-Nomex kV meter.
When measuring the kV non invasive a correction factor from the user manual of the
kV-meter has to be used. If a kV meter is not available and if it is within local laws and
regulations, the measurement can be made with an oscilloscope on D1. KVPEAK - D1
GND with a result of 40 kV/V.
NOTE
•
For the actual filtration of this MOBILETT, see the test protocol.
If the actual inherent filtration is unknown, the correction shall be made with a reference
value of 5 mm Al.
•
Put the kV meter into operation, see operating instructions for the kV-meter.
•
Place the measurement detector on a table or other. Using the light field, set the detector
in the beam projection, see Fig. 5.
•
Set the SID to approx. 50 cm (20"). The SID may vary between different kV-meters.

Higher filtration results in higher kV values.
If the MOBILETT is equipped with a DAP measuring system;
Remove the DAP ionization chamber first.
