Start-Up and Operation
AET (automatic exposure time) and AGC (auto gain control) automatically ensure the correct
brightness of the image when the setting is at "Continuous".
The settings are "Once" / "Continuous" / "Off".
In some situations (e.g. strong contrasts on the specimen) the automatic setting may cause the
image to be under- or overexposed. In this case the automatic setting can be deactivated by
switching to "Off".
A shorter exposure time with higher amplification (= more noise, but smoother live image) or a
longer exposure with lower amplification (= less noise, less smooth live image) can be selected in
"Off" mode.
In "Once" mode a one-time automatic adjustment will be carried out when confirmed with OK,
but then deactivated again.
Influences the AET / AGC control when "Continuous" mode is set.
Extreme left: very dark image
Extreme right: very light image
The exposure time can be set within the range 20 µs to ~2s. The exposure time may be set
automatically or manually. Manual setting is possible by selecting the AET / AGC control in "Off"
mode.
Extreme left: 20 µs
Extreme right: 2000 ms (2 s)
The sensor amplification function can be set within the range 1x to 8x. Sensor gain may be set
automatically or manually. Manual setting is possible by selecting the AET / AGC control in "Off"
mode.
Extreme left: no increased amplification
(less image noise, less light sensitivity of sensor)
Extreme right: maximum amplification
(strong image noise, high light sensitivity of sensor)
