What to do if the CPI Portable Generator displays 'Requested density not programmed'?

R
Robin MacdonaldOct 31, 2025
If the CPI Portable Generator displays a message indicating that the requested density is not programmed, you can try the following: * Select another density or program the requested density step. * Recalibrate the X-ray tube or select a calibrated parameter. * Reset the DAP. * Re-evaluate technique factors and allow the generator to cool if possible, to prevent overheating. * Allow the generator to cool sufficiently to allow the requested exposure. * Select a valid parameter. * Wait for the anode to cool. * Reset the time and date. * Power the unit off and retry the rotor start. * Check for an open filament in the X-ray tube, poor connections in the cathode cable, and fuses on the filament board(s). * If arcing of the X-ray tube is suspected, check the condition of ...
