settings are deleted
when the MC 1500
is switched off
11. Strobe mode:
Illumination not
pulsating
12. Strobe mode:

light pulse too weak
Possible causes and remedial action
Has the LED unit to be set already been
selected? If necessary select using switch (1)
(also see Section 8.2 or 8.4).
Have the memory keys already been
programmed? If necessary save different
illumination conditions by pressing down the
M key together with one of (M1) to (M4) keys
Default values are set when the MC 1500 is
switched on. Please save individual settings in
memory stations before switching off controller.
Is strobe activated? Select required illumination
unit using (1) and activate strobe mode (9).
Is strobe frequency too high, strobe intensity
too low or strobe pulse duration too long?
Optimize variables. If necessary set strobe
intensity individually for both LED units
(see Section 8.6).
Is movement of the specimen periodic with a
constant frequency? Only then are stationary
images possible.
Optimize strobe frequency (see Section 8.6).
Please decrease strobe pulse duration.
If necessary increase strobe intensity individually
for each unit (see Section 8.6).
Preferably activate strobe mode for both VisiLED
units. If that is not desirable reduce the
brightness of unit that shall not strobe to
required minimum.
If necessary reduce ambient light.
Is intensity or duration of light pulse too low?
If necessary increase values using PC control
(also see Section 8.6).
