Table 2-2. Settable Profile Parameters (cont.)
Parameter Description
Fluoro Type [2]
(Fluoro only)
Sets the Fluoro type to continuous (CONT) or pulsed.
Target/Filter Sets the Target/Filter option.
Delay [2]
(Radio, mammo, dental only)
Sets a delay (0 to 999 milliseconds) to postpone the start of data analysis in
order to skip over waveform anomalies that can occur at the beginning of
an exposure. See the How to Enter a Delay section.
Include Delay [2]
(Radio, mammo, dental only)
Set this option when waveform anomalies, such as leading edge
overshoots are to be excluded from kV measurement but included in
exposure time measurement.
Deselect this option when waveform anomalies, such as filament preheat
pulses are to be excluded from kV and exposure time measurement.
[1] If 0% is selected, the Detector measures radiographic exposure time from the moment x-rays are detected until they are no longer
detected. Otherwise, the Detector measures exposure time between the 75 %, 80 %, 90 % points on the kV waveform respectively.
[2] Parameter is not user settable in Auto profile.
[3] In the TNT 12000 PTB version, only Gy (Gray) is available.
Not all parameters are available in all four measurement modes. Dose Rate Units and
Fluoro Type are only available when the Detector is set for the Fluoro measurement
mode. Time Units, %kV, and Delay are not available in Fluoro mode. All parameters can
be set manually or some of the parameters can be set automatically.
There are three standard profiles for each measurement mode: Manual, Auto, and
Default. These 12 profiles are kept in memory. Each profile is defined by the values set
for each parameter contained in the set. The value of each parameter in the Manual and
Auto profiles can be changed and put in memory. The default profiles are factory defaults
and can not be changed.
You can make a maximum of five user-defined profiles for each measurement mode.
These 15 user-defined profiles add to the standard 12 profiles.
How to Set a Detector Profile
To set measurement parameters in the X-ray Detector, a profile is recalled from memory
and used to setup the Detector.
To set the X-ray Detector measurement mode parameters:
1. Highlight the Settings button in the MODE SETUP screen or the middle button in
the MEASUREMENT screen. The name on the middle button shows the
measurement profile selection.
2. Push E to open the MEASUREMENT SETTINGS screen.
