Electric errors
These may be:
1. The lamp on the microscope does not work.
2. There is no power.
Check the following possible causes:
The on/off switch does not respond
(no illumination):
●
Check that all mains cables are properly con-
nected.
●
Make sure that there is power at the sockets
you are using and that they are not
deactivated by a mains switch.
●
After you have ruled out the possibility of all
possible external sources of error, check that
a fuse of the Leica DM IRB or power unit is not
defective.
Replacing the mains fuse on the microscope
n. b.:

●
Make sure the plug of the lamp cable is firmly
plugged into the corresponding socket on the
back of the DM IRB stand.

Apart from preparation errors (e. g. staining or
wrong specimen vessel), which cannot be dealt
with in this manual, there are two main
categories of error:
Mechanical errors and
electric errors.
Mechanical errors
We already mentioned possible mechanical
errors in the “Installation” and ”Operation”
chapters.
These mainly involve errors in inserting con-
trasting equipment, maladjustment of light rings
or the wrong condenser height setting.
We described all these possible errors in pre-
vious chapters.
Therefore, if you are not satisfied with the
quality of the image, read the relevant sections
of the manual.
