7.0 Re-Adjustment of kV This adjustment has to be done after connecting all connectors completely. Actual x-ray exposure is necessary. This adjustment requires that an exposure be made. Please observe all radiation related safety precautions. Confirmation is surely necessary after the re-adjustment of kV. Direct kV test is necessary using kV test instrument such as the VICTOREEN NERO.
Page 16
7-1. Adjustment of 80 kV by VR3 Adjust the ch1 (EP) by VR3 to be 1.9 V ±0.05 V. Turning clockwise increases kV. 7-2. Adjustment of 120 kV by VR3 Adjust the ch1 (EP) by VR3 to be 2.9 V ±0.1 V. Turning clockwise increases kV.
8. 0 Re-Adjustment of mA This adjustment has to be done after connecting all connectors completely. Actual x-ray exposure is necessary. This adjustment requires that an exposure be made. Please observe all radiation related safety precautions. ※This adjustment should be done whenever Insert Box or Inverter PC Board (M9171A PCB) is replaced.
Page 18
8-2. Adjustment of 60mA at 40kV by VR4 Adjust the ch2 (IP) by VR4 to be 2.9 V ±0.3 V. Turning clockwise increases mA. 8-3. Adjustment of 20mA at 120kV by VR4 Adjust the ch2 (IP) by VR4 to be 0.95 V ±0.1V. Turning clockwise increases mA.
9. 0 Re-Adjustment of Pre-heat value This adjustment has to be done after connecting all connectors completely. Actual x-ray exposure is necessary. This adjustment requires that an exposure be made. Please observe all radiation related safety precautions. ※This adjustment should be done whenever Insert Box or Inverter PC Board (M9171A PCB) is replaced.
