14 User statement Measurement criteria for exposure time Exposure time Consists of beginning and ending points as measured by a calibrated x-ray monitor at 70% of the peak radiation waveform kV The high voltage mean value received after measurement with a calibrated x-ray monitor mAs The resistance value divided by voltage. A calibrated x-ray monitor measures the voltage over feedback resistor and provides a mAs value. The nominal x-ray voltage 85 kV is obtained at highest tube current 13 mA. NOTE! Exact value is 12,6 mA. This value has been rounded upwards to 13 mA. The nominal tube current 16 mA is obtained at the highest tube voltage 77 kV. The highest electric power is obtained at 77 kV tube voltage and 16 mA tube current. The nominal electric power of 1232 W is obtained when loading time is 0.1 s and nominal x-ray tube voltage 77 kV is used.
