Appendix B Calibration (DiRex System)
Revision W HF Series X-ray Generators - Service Manual
B-4 Quantum Medical Imaging, LLC
OVERVIEW
This appendix provides instructions for configuring and calibrating the HF Series X-ray
generator using DiRex interface program installed on the Agfa CR system’s worksta-
tion computer (refer to DiRex Service Manual DC30-088 for system interconnection
and software OCP installation instructions). With DiRex, the workstation computer
functions as the generator operator control panel (OCP). The X-ray generator must be
equipped with the "Q-Connect option" (i.e., CR/DR system integration) to enable
DiRex functionality.
NEMA Standards Publication/No. XR8-1979(R1994), Test Methods for Diagnostic X-ray
Machines for Use During Initial Installation is recommended as a reference.
REQUIRED TOOLS AND MATERIALS
The following lists the tools and materials required to perform the procedures
contained in this chapter:
• Digital Voltmeter: Fluke Model 87 (or equivalent)
• Non-invasive kV, mAs, mR meter or Radcal Dynalyzer III (or equivalent)
• Oscilloscope, 50 Mhz storage: Tek 2210 (or equivalent)
• 5 CM, 10 CM, 15 CM, 25 and 30 CM acrylic phantoms (required for
calibrating systems equipped with QG-AEC option).
SYSTEM CONFIGURATION/CALIBRATION
The HF Series x-ray generator has been factory configured and calibrated. It is nec-
essary, however, to perform the following procedures to verify system performance.
Perform the procedures in the sequence presented, unless otherwise instructed.
ACCESSING SERVICE MODE
Calibration and configuration can only be performed by accessing the X-ray gen-
erator’s Service Mode. To gain access to the Service Mode, password entry is
required. This is to prevent unintended and/or unauthorized changes to system
settings. To access the Service Options Menu, proceed as follows:
1. Ensure the DR or CR system’s Computer Workstation is properly connected to
the generator, and the DiRex System (i.e., Quantum/Agfa Integration) soft-
ware is installed and configured in accordance with the instructions provided
in DiRex Service Manual DC30-088.
2. Ensure the Power/Expose Control Box (AY20-265) is properly connected to
the generator as described in Chapter 2, ASSEMBLY & INSTALLATION.
3. Set the ON/OFF circuit breaker CB1 on the generator cabinet to ON position.
4. Set the power on/standby switch on the Power/Expose Control Box to the
standby ( ) position, then to the on ( ) position. The green power LED
lamp should illuminate.
