1
On some combinations of kV and mAs there may be a single 2 millisecond kV
overshoot of up to 10% at the beginning of the exposure.
2
mA and Time may be specified by the operator in the 3 point mode only.
Note: In 2 point mode, at low kV and mAs (less than 5 mAs) the pre-indicated time
may vary from the actual time by 50%. Since the radiation output is determined by
kV and mAs only, the pre-indicated time has no direct effect on the actual exposure
dose.
