TIME mode (long-time exposure control)
Pressing the <TIME> button activates (long) TIME exposure control. Press the <START> button to
open the shutter (start exposure). Press
<START> again to close the shutter (end
exposure).
During the exposure, the time is counted
upwards in steps of 1 s. After completion of the
exposure, the display shows the time for which
the shutter was open.
The longest possible exposure time is 9999 s.
When this time is over, the exposure is
automatically stopped.
2.3.6
Saving the exposure time
If you press the <STORE> button, the exposure
time determined in the AUTO mode is kept
constant for any number of exposures, until
you press <STORE> again to cancel the saving
function.
The active state of the saving function is
indicated on the LCD display by the comment
“STORE” instead of “AUTO”.
This function can be used for the following
purposes:
Capturing larger specimen areas by a series
of exposures (excludes the influence of
different area coverages by the specimen
detail on exposure time).
Making visible differing light intensities in
multiple fluorescence work.
