Test Of Kv Accuracy; Kv Meter Method - Siemens MOBILETT XP Digital Installation And Startup

DHHS

Test of kV accuracy

Requirement:
The measured kV values must comply with the limit values specified in the tables. One of
two measuring methods can be used:
1. kV meter procedure:
- kV meter based on the filter comparison technique (e.g. PTW-Nomex). Use the cor-
rection factor given in the kV meter operating instructions for non-invasive kV mea-
surements.
2. Oscilloscope method:
- Storage oscilloscope with a measuring accuracy of ± 2.5%

kV meter method:

NOTE
•
Switch the MOBILETT XP Digital on.
•
Maintain or switch to manual operation of the MOBILETT XP.
•
Prepare the kV meter for the measurement according to the operating instructions.
•
Place the measuring detector on a suitable surface and adjust the single tank to the de-
tector using the light localizer
•
Set the source-to-image distance to the value specified in the kV meter operating in-
structions.

The inherent filtration (Al equivalent) of MOBILETT XP Digital is
3.1mm Al (single tank plus collimator).
An installed DAP measurement chamber increases the inherent fil-
tration by 0.4 mm AL.
