CHECK MANUAL COMPRESSION
You must check that the maximum force which can be applied by manual compression is within limits.
1. Set the Compression Arm to the vertical position.
2. Place a phantom on the Bucky.
3. Turn the manual compression knob to apply compression to the phantom until the torque limiter pre-
vents any further increase in compression. Note the value of compression displayed on the Gantry
readout.
! Notice:
When applying compression, use your fingers to turn the compression knob. Do not allow the mass
of your hand and arm to rest on the knob, as this could affect the value of compression.
4. The compression reading must be between 27 daN and 30 daN.
If the reading is in this range, no calibration is required and the check is complete.
5. If the reading is outside the specified range, the torque limiter must be calibrated.
Continue with the appropriate procedure as described in section
