Troubleshooting 3D Microscopy12 B 40-022-4 e 07/982.4 TroubleshootingThe monitor displays colored fringing orseveral out-of-focus images: Switch off MCU II;switch it on again after 10 secondsNo 3D image is obtained: monitor shutter does not function;check switch for monitor shutter on thecontrol unit; the green lamp lights up only ifthe switches are set correctly parameters on the MCU II are not setcorrectly;check the parameters, mainly Time,MEMORY IN, MEMORY OUT camera not positioned correctly;check whether the camera controls arealigned perpendicular to the stand andwhether the monitor image follows thestage motion;if not, turn the camera 3D illumination shutter is out of alignment;recenter aperture diaphragm,recenter 3D illumination shutter Knob of 3D-CONTROL DAS-3 control unitsnot set correctly;check 3D setting of 3D-CONTROL DAS-3The image flickers: pulse rate is not set correctly;set 3D VIS on the 3D CONTROL DAS-3 forobservation, and 3D VIDEO for monitorobservationA pseudostereoscopic image is displayed,i.e. heights and depths in the image areexchanged: The toggle switch of the 3D CONTROL DAS-3 is not set correctly;set toggle switch to "STEREO" For observation, exchange eyepieces for 3Dshutter For monitor observation,set toggle switch of 3D CONTROL DAS-3 to"STEREO";if required, change "Scope LCD" parametersin the CONFIG menu of the MCU II For monitor observation,set the switch of the control unit for themonitor shutter to "stereo mode"Note:If inverted microscopes are used in transmittedlight - e.g. the Axiovert 100/135/135 M -remember that observation is made from theopposite side of the instrument if manipulators,needles and electrodes are used.
