Limits
can be modified within the range of the value fields.
The displayed default limit values are higher than the values which can be
selected at the control desk.
Values should not increase the local
regulation limits.
The shortest exposure time possible is
1ms.
A short exposure time in combination with a low emission current
can cause an error 00L$
if the resulting mAs value is below 0.5 mAs (only if sent online with AGenT2).
The max exposure time which can
be selected at the control desk is always 16000
ms.
If tomo is programmed the max
exposure time is 6000 ms.
60000 ms is only available if ‘CT add on’
has been selected at ‘RGDVx Data Set B’ and if option is present.
The max time limit for AEC must not be shorter than 4000 ms, 6000 ms for TDCOtherwise
error 00L3 comes up and the generator might be dead afterwards. |
0.5
mAs is the lowest value one can select at the control desk (any non-AEC
technique RUIT
= kV-mA-ms, RUQ = kV-mAs, RUQT = kV-mAs-ms).
A
short exposure time in combination with a low emission current can cause an
error 00L$ if
the resulting mAs value is below 0.5 mAs (only if sent
online with AGenT2).
AEC
= AEC falling load, AECF = AEC fixed
current and TDC = Tomo Density
Control
techniques have a default max mAs
limit of 580 mAs programmed to meet
the HHS limit of
600mAs (AEC and AECF use the same limit).
Even if the non-AEC techniques
RUIT, RUQ, RUQT show 1000mAs as default limit,
the absolute limit which can be selected at the control desk is 850mAs.
It can also be selected in HHS countries which are limited at 600mAs for AEC
exposures.
