NOTE
The signal contains a high frequency of 20-40 kHz, which can lead
to measurement problems with the oscilloscope (aliasing effect).
Always use an oscilloscope with a high sampling rate.
X • Calculate the product of the tube current x the exposure time for the following exposure
parameters:
* The measurement inaccuracy for the measurement device must be subtracted from
these limit values.
• Determine whether the mAs product (tube current + reactive current) x exposure time
lies within the indicated tolerances.
Setting
• Proceed according to section "P10 - Fast adaptation" in the Service Instructions to elim-
inate slight deviations.
PMF mAs accuracy 40 kV, 5 mAs (B)

PMF mAs accuracy 133 kV, 10 mAs (B)
• Connect the power supply plug and switch the main switch to position "M".
X
• Set the following exposure parameters and release an exposure:
• Disconnect the power supply plug, roll up the cable and switch the main switch to posi-
tion "B".
