### X-Mode Limits

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.

#### Min. Time Limit [ms]:

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).

#### Max. Time Limit [ms]:

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 TDC Otherwise error 00L3 comes up and the generator might be dead afterwards.

#### Min. Current Time Product Limit [mAs]:

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).

#### Max. Current Time Product Limit [mAs]:

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.
