Troubleshooting

Image Output to a PC Monitor

• Shading correction read may have been failed.

Restart the DS-U3.

• Motion-blur can occur when capturing images of a moving subject with

DS-Fi1 or DS-Fi1c in interlaced mode. It is not a system failure.

• The AE function may be unstable during peak hold photometry under

some imaging conditions.

• Check that the tone is adjusted correctly with the application software.

⇒ Refer to the instruction manual for the application software.

• Check that the black level is set appropriately with the application

software.

⇒ Refer to the instruction manual for the application software.

• Check that the size of the field diaphragm is adjusted so that it

circumscribes the view field.

• Check that the size of the aperture diaphragm is adjusted to

approximately 70% to 80% of the numerical aperture of the objective

lens.

• Check that an appropriate filter is used.

When using a phase contrast microscope or an interference microscope

(two luminous fluxes or multiple luminous fluxes), insert the specified

filter. With a black and white image, contrast is improved by inserting a

green interference filter (GIF). Contrast in color images is enhanced by

inserting a filter having a complementary color to that of the specimen.

• Check that the ambient light around the microscope does not affect.

If the ambient light affects, darken the room or attach a cap to the

binocular eyepiece.

• Check that the contrast of the specimen is sufficient.
