7. Place the R100 in front of the image intensifier but outside the measuring field for
the mA feedback loop. You may use the optional detector rod that can be attached
to R100 to position the detector without risk for hazardous X-ray exposure. Observe
the image on the monitor.

Since the external dose probe (R100) is not sensitive to back scatter, a
lower value compared to a transmission ion chamber is typically detected
(typically in the range of 5 - 20 %).
You may use the beam correction factor to make automatic corrections. The
beam correction factor may also be stored permanently in a Favourite for
easy access.
