FLUORO 75%
MAMMO 80% LOW
RADIO 90% HIGH 10 ms
MODE %kV SENS DELAY
Select the RADIO mode, %kV, high or low sensitivity and measurement delay, then press the ENTER
key. To use a measurement delay, press the DELAY key to select and increment the delay. The delay
may also be incremented or decremented by pressing the up or down keys when the delay is selected.
Select the interval, as a percentage of kV peak, over which exposure time is measured, using the %kV
key. ZERO selects measurement between the zero crossings on the rising and falling edges of the kV
waveform. 1ØPULSE selects the single-phase pulse counting mode for exposure time measurement.
The measurement delay and %kV settings are retained from one exposure to the next.

FILTER = 50 - 100
RADIO 75% LOW 10 ms
MODE %kV SENS DELAY
Please wait while the Model 8000 prepares to take an exposure. Note that the selected filter kV range is
displayed. The kV filter range may be changed at any time without exiting from the measurement mode.
If the Model 8000 detects a fault condition such as an invalid filter card or position, an error message is
displayed and the user must correct the error to continue (see Section 4.3--Error Messages--for more
information). When the Model 8000 is ready for an exposure, it will beep and prompt for an exposure.
MAKE EXPOSURE
FILTER = 50 - 100
RADIO 75% LOW 10 ms
MODE %kV SENS DELAY
Make an exposure. If nothing happens, there is insufficient x-ray intensity to make a measurement. To
remedy this situation, switch to high sensitivity, switch to the next lower kVp filter range (if possible),
increase mA or decrease the distance between the x-ray tube and Model 8000 detector.
