I.I. 6
• Mount the I.I. back on the C-arm flange. The labels should face the C-arm.
• Reinstall the attachment screws in the threaded holes. Turn them at least 5 revolutions.
• Holding the I.I. firmly, swivel the C-arm so that the I.I. is above and the SIREPHOS is be-
low.
• Carefully lower the I.I. into the service position.
I.I. Mini voltage supply 6
• Reinstall the high voltage section of the I.I. mini voltage supply.
• Reconnect the control section, however, do not tighten the screws yet.
• Route the cables to the high voltage section and the control section and secure them
with cable ties or cable clamps.
VIDEOMED DC 6
• Rotate the Compact optics into the 0° position (slowly!).
• Connect an ohmmeter to the potentiometer for camera rotation, point 2 and 3.
At 0° , there should be a resistance value of 5000 ohms, +
40 ohms.
• Place the VIDEOMED DC in the 0° position on the compact optics and secure it with the
clamp. Refer also to chapter 6, Replacing the VIDEOMED DC.
Miscellaneous parts 6
• Mount the grid to the new I.I. Attach the wires for the cassette contact.
• Reroute and reconnect all the cables (protective conductor, cables etc....).
Checks and adjustments 6
• Check the I.I. electrode voltages according to the test protocol for the I.I. and adjust
them.
• Check the resolution. If necessary, adjust the optical sharpness on the Compact optics.
• When doing this, use the I.Q. Quick test, chapter: Resolution for evaluating the optical
sharpness.
• Check the dose rate and, if necessary, adjust it.
• Check that the camera optics are centered to the I.I. output and, if necessary, adjust
them. Refer also to chapter 6: Replacing the Compact optics, paragraph "Checking the
camera optics centering at the I.I. output" and "Centering the Compact optics to the I.I.
output".
• Check the camera rotation and, if necessary, adjust it.
