2.5.3 Fluoro Mode
Fluoro mode is used to make measurements on fluoroscopic x-ray generators. Fluoro mode supports
both continuous fluoro and pulsed fluoro measurements. In the continuous fluoro mode, the NERO mAx
measures kVp, exposure rate (R/min) and mA. In the pulsed fluoro mode, the NERO mAx measures kVp,
exposure rate (R/min and mR/pulse) and mAs/pulse.
To make a continuous fluoro measurement
Make sure that the NERO mAx is turned off. Plug one end of the NERO mAx’s detector cable into the
NERO mAx detector. Plug the other end of the detector cable into the NERO mAx’s detector connector.
Insert the W/Al filter card into the detector and place the filter card in the correct position for the kV range
to be measured. Place the NERO mAx detector on the x-ray table with the top of the detector facing the
x-ray tube. Position the detector so that the detector is centered in the beam and is aligned with the x-ray
tube axis. If mA measurements are to be made, plug the mAs cable into the NERO mAx detector’s mAs
input and connect the mAs leads to the generators mAs terminals. For more information on positioning
the NERO mAx detector, see section "Positioning the Detector". For mA limits vs. kV, refer to Appendix
B.
WARNING
Extreme caution should be used when making
connections to the mAs terminals of the X-ray
generator or detector. Improper connections may
result in injury, damage to the NERO mAx, and/or
damage to the x-ray generator.
If results are to be printed, plug the printer cable into the printer port at the rear of the NERO mAx then
plug the other end of the printer cable into the printer and turn the printer on (see Section 1.5--Printing).
Plug the AC adapter into the NERO mAx if needed (see Section 1.4--Battery Operation and Charging)
and turn the instrument on.

Please wait while the NERO mAx prepares to take an exposure. Note that the selected filter kV range is
displayed. If the NERO mAx detects a fault condition such as an invalid filter card or position, an error
message is displayed and the user must correct the error to continue (see Section 4.3--Error Messages--
for more information). When the NERO mAx is ready to take an exposure it will beep and prompt for an
exposure.
