Repeat the 15-second exposure and record the values for Fluoroscopic Exposure Rate #2, Fluoroscopic
mA #2, and Fluoroscopic kVp #2, respectively.

2.4 Fluoroscopy High Level Exposure Rate Data


The following measurements are to be made only
on those systems that have the High Level option.
Do not make this measurement for Manual
systems.


Set the electrometer selector switch to the "Exposure Rate" mode. Without making any changes in the
standard patient techniques, with the phantom and probe properly positioned and the beam collimated to
the four markings on the phantom, place the system in the High Level mode of operation and make an
exposure of at least 15-second duration. Record this exposure rate as Fluoroscopic High Level Exposure
Rate #1. Record the selected kVp as Fluoroscopic High Level kVp #1. If the unit has an mA indicator,
read and record the mA value during the 15-second exposure as Fluoroscopic High Level mA #1. Reset
the electrometer to zero and repeat the 15-second exposure and record the values for Fluoroscopic High
Level Exposure Rate #2, Fluoroscopic High Level kVp #2, and Fluoroscopic High Level mA #2,
respectively.

2.5 High Level Fluoroscopy Exposure Rate Data with Barium

Simulation (Copper)


The following measurements are to be made only
on those systems that have the High Level option.
Do not make this measurement for Manual
systems.


Set the electrometer selector switch to the "Exposure Rate" mode. Without making any changes in the
standard patient techniques, with the phantom and the probe properly positioned and the beam
collimated to the four markings on the phantom, select High Level mode of operation, and make an
exposure of at least 15-second duration. Record this exposure rate as Fluoroscopic Copper High Level
Exposure Rate #1. Record the selected kVp as Fluoroscopic Copper High Level kVp #1. If the unit has an
mA indicator, read and record the mA value during the 15-second exposure as Fluoroscopic Copper High
Level mA #1. Reset the instrument to zero, repeat the 15-second exposure and record the values for
Fluoroscopic Copper High Level Exposure Rate #2, Fluoroscopic Copper High Level kVp #2, and
Fluoroscopic Copper High Level mA #2, respectively.

2.6 Maximum Fluoroscopy Exposure Rate Data (with Copper

and Lead)

Do not make this measurement for Manual

systems.
