RaySafe Solo - Manual (Page 25)

pASSIVe mAs
It is possible to measure mAs simultaneously when using the RaySafe Solo R/f with mAs. the instrument
will trig on radiation, not on the current in the mAs cable. Any initial rush current will thus be excluded. the
measured mAs value automatically appears in MEASURE MODE on the display.
on some X-ray equipment the tube current does not drop below 25% of peak at the end of the exposure or the
generator give a second current pulse within 0.5 ms. the result is a long time measurement which gives a low
mA calculation. these situations are suitable for passive mAs. follow the steps below to measure passive mAs:
1. Connect the R/f detector to the RaySafe Solo base unit.
2. Connect the mAs cable to the base unit.
3. Connect the black and red banana plugs of the mAs cable to the mA/mAs port of the generator.
4. place the R/fdetector in the X-ray field.
5. Make the exposure.
