Measurement Base of Technique Factors
The kV is measured during pre-pot testing using a calibrated high voltage divider with a guaranteed
accuracy of ±2%. Final performance measurements are made using a NERO mAx, model 8000 X-ray
meter from Victoreen. Tube current is sensed across a series connected resistor with an accuracy of
±1% and measured using a digital multimeter, prior to encapsulation; NOMAD Pro has no provision
for external measurement of beam current after final manufacture. Exposure time is measured during
the entire exposure, referenced to 75% rise/fall, using the NERO mAx 8000 x-ray meter.
