The 6 V/30 W halogen
lamp flickers, its light in-
tensity is unstable, the il-
lumination inhomoge-
neous
End of average service life of 6
V/30 W halogen lamp has
been reached.
Replace the 6 V/30 W halogen
lamp.
Power cable incorrectly in-
stalled or broken.
Connect the power cable cor-
rectly or replace it.
The pins of the 6 V/30 W halo-
gen lamp have not been in-
serted correctly into the lamp
holder.
Insert the pins of the 6 V/30 W
halogen lamp correctly into
the lamp holder.
The pins of the 6 V/30 W halo-
gen lamp have not been in-
serted symmetrically into the
lamp holder.
Insert the pins of the 6 V/30 W
halogen lamp symmetrically
into the lamp holder.
Stage comes down by it-
self, image focus is unsta-
ble
Adjusted torque of coarse fo-
cusing drive is too low.
Increase the torque of the
coarse focusing drive to make
motion stiffer.
Transmitted-light illumi-
nator of the microscope
with iLED cannot be
switched on.
Transmitted light/reflected
light changeover switch is in
reflected light (
Fluorescence
)
position.
Turn transmitted light/re-
flected light changeover
switch to transmitted light
(
Brightfield
) position.
Reflected-light illuminator
of the microscope
with iLED cannot be
switched on.
Transmitted light/reflected
light changeover switch is in
transmitted light (
Brightfield
)
position.
Turn transmitted light/re-
flected light changeover
switch to reflected light (
Fluo-
rescence
) position.
Reflected-light illuminator not
sufficiently aligned to micro-
scope stand or displaced,
causing interruption of power
supply by interlock function.
Align reflected-light illuminator
exactly to microscope stand
and tighten clamping screw
sufficiently.
The X direction range is
smaller than expected.
Normal behaviour after long
hours of use.
Recover the stage travel range:
§
Hold the specimen
holder's two screws.
§
Unsing the control knob,
move the specimen holder
to the left and right until it
hits the end stop.
The stage travel range is
reset.
