High signal
One or several detectors have too high signal.
Lower the set sensitivity under settings.
Reduce the mA and/or increase the distance from tube to
detector.
Exp. < Delay
The exposure time is too short compared to the delay time.
Increase the exposure time and/or reduce the values of
delay and/or window time.
Keep in mind that the type of measurement sets the delay
time value. The standard value for radiography use is 5 ms,
but for dental it is 200 ms. See Measurement Type Settings
.
High kVp
Measured tube voltage is higher than that of the selected
kV-range.
Change to a higher kV-range.
Low kVp
Measured tube voltage is lower than that of the selected kV-
range.
Change to a lower kV-range.
