Check the X-ray tube current with the tube ammeter (MA-1201D)
Measure the X-ray tube current with an external tube ammeter wired into the anode side of the high-voltage circuit, then convert that anode-side reading to the actual cathode-side tube current using the CXB-400C's 0.9 conversion factor.
Applies to
Activion16 (TSX-031A) X-ray generator/HV section, X-ray tube CXB-400C. The 0.9 cathode-side conversion factor given here is specific to the CXB-400C; source states the calculation \"differs depending on the tube used\" without giving another tube's factor in this section.
