Troubleshooting
General checklist for error situations and non-standard events:
•
Has installation or cabling work been correctly performed (see section 3 on page 19)?
Check the cabling of the Auto Focus.
•
Are cable ends firmly seated in their sockets?
•
Was the Switching on procedure duly followed (see section 4.1 on page 22)?
•
Is the beam splitter of the camera deflection in the beam path?
•
Is the correct camera deflection installed?
•
Are the cables of the Auto Focus under mechanical strain? Check the cables and ensure that they are
free from strain.
•
Have the objectives been calibrated? Repeat or renew the focal position calibration.
•
Is the active objective correctly displayed in the TFT display?
•
Has a sample actually been inserted and a typical region on the sample been selected?
Shift to a different XY position of the sample. Pronounced irregularities / scratches on the sample may
result in disruptive reflections at the current sample position.
•
Does the sample have structures which run parallel to the Auto Focus stripe structures? Reposition the
sample or, if this is not possible, select a different angle setting for the Auto Focus sensor.
•
Which type of sample has been inserted? It may be necessary to change the surface of specimen
setting (Reflective / Partially reflective / Diffuse).
•
Is the stage Z-position far outside of the capture range of the objective? Use a lower objective
magnification for refocusing or make a rough focus manually.
•
Is a sample with a cover glass being used? Only EC Epiplan objectives (with magnification of 10x or
less) and EC Epiplan-Neofluar objectives (with magnification of 10x or less) from the list of compatible
objectives can be used for samples with a cover slip.
