6.5 Setting the Exposure Time
All Models Except the acA1920-25um/uc, acA2500-14um/uc, acA3800-14um/uc,
acA4600-10uc
If you are operating the camera in any one of the following ways, you must specify an exposure time
by setting the camera’s Exposure Time parameter:

the frame start trigger mode is set to off

the frame start trigger mode is set to on and the trigger source is set to software

the frame start trigger mode is set to on, the trigger source is set to Line 1, and the exposure
mode is set to timed.
The Exposure Time parameter must not be set below a minimum specified value. The minimum
setting for each camera model is shown in Table 21.
The maximum possible exposure time that can be set (in [µs]) is also shown in Table 21.
This section (Section 6.5) describes how the exposure time can be adjusted
"manually", i.e., by setting the value of the exposure time parameter.
The camera also has an Exposure Auto function that can automatically adjust the
exposure time.
Manual adjustment of the exposure time parameter will only
work correctly, if the Exposure Auto function is disabled.
For more information about auto functions in general, see Section 8.11 on
page 209 .
For more information about the Exposure Auto function in particular, see
Section 8.11.5 on
page 219 .
