Objectives Information
Depending on which objective is being used, before turning the
nosepiece to change magnifications, the nosepiece will need to be lowered with the
course focus knob otherwise the objective may crash into the stage if caution is not used.
Possible Brightfield Mode Operational Problems
If normal adjustments are not getting the results you expect, check to see if these
conditions exist:
• Incorrect condenser / objective combination being used
• Incorrect components inadvertently installed
• Dirty or smudged optics
