Why is the burner flickering or dark on my Olympus U-RFLT50?
- H
  Hunter DavisAug 17, 2025
  If the burner flickers or appears dark on your Olympus Laboratory Equipment, several factors could be the cause. First, the auto ignition interlock mechanism might be activated; in this case, press the switch inside the starter reset hole on the right side of the power supply unit, and then press the main switch to “ I ” (ON) again. If insufficient time has elapsed since turning on the burner, wait at least 10 minutes. Also, check that the voltage selector switch and/or frequency selector switch are correctly set to match your local AC mains. If the burner life has expired (typically after 100 hours), replace the mercury burner. Finally, ensure the input voltage selector switch is correctly set to match your local AC mains.

  Casey MillerAug 22, 2025
  If the main switch indicator lights up but the mercury burner fails to ignite on your Olympus Laboratory Equipment, consider these possible causes: Begin by checking all connectors to ensure they are properly connected. Confirm that the burner is correctly installed. Inspect the lamp housing interlock mechanism and tighten the burner socket clamping screw if it's activated. If these steps don't resolve the issue, the auto ignition may be malfunctioning; try turning the main switch on the power supply unit OFF and then ON again, repeating as necessary.

  Melissa PowellAug 28, 2025
  If the main switch of your Olympus Laboratory Equipment can be set to ON, but the burner does not ignite, there are several possible reasons. First, ensure the lamp housing connecting cord is properly connected. Second, check if the mercury burner is mounted. If not, attach one. Third, the safety mechanism in the lamp housing might be activated; tighten the lamp burner socket clamping screw firmly. Lastly, the auto ignition system could be malfunctioning. Try setting the main switch of the power supply unit to OFF and then ON again.

Why does the mercury burner flicker or have low brightness on my Olympus Laboratory Equipment?
- K
  Kyle Montoya MDAug 31, 2025
  If you're experiencing a flickering mercury burner or low brightness with your Olympus Laboratory Equipment, it could be due to several reasons. One possibility is that the auto ignition safety mechanism is activated. To resolve this, press the switch inside the starter reset hole on the right panel of the power supply unit, and then set the main switch to ON again. Another reason might be that you are observing this phenomenon shortly after ignition, in this case wait for 10 minutes or more after ignition. Ensure that the power supply voltage and frequency switches are set correctly. Finally, the burner life might have expired, requiring you to replace the mercury burner.

Why is the edge of the field of view obscured on my Olympus Laboratory Equipment?
- D
  Deborah JohnsonSep 2, 2025
  If the edge of the field of view is obscured or unevenly illuminated on your Olympus Laboratory Equipment, consider the following: * Ensure the objective is properly engaged in the light path by making sure the revolving nosepiece clicks into place. * Verify the fluorescent mirror is correctly engaged in the light path. * Check that the filter slider is fully in the open position and not stopped halfway. * Confirm the ND filter is also fully engaged and not stopped halfway. * Adjust the centering of the mercury burner. * Adjust the collector focus position to an optimum setting.

Why is the visibility poor and the image not sharp on my Olympus Laboratory Equipment?
- B
  Brenda MontesSep 8, 2025
  If you are experiencing poor visibility, a non-sharp image, or poor contrast with your Olympus Laboratory Equipment, there are a few potential causes. First, if you're using a 40X objective, it may be inaccurate, or the correction collar may not be properly adjusted; use the objective with correction collar and adjust it to find the best position. Second, the objective or filter might be dirty, so clean them thoroughly. Third, the field iris diaphragm may be adjusted improperly; adjust it so that it circumscribes the field of view.

Why are the service lives of mercury burners very short in my Olympus Laboratory Equipment?
- I
  ian71Sep 12, 2025
  If the service lives of mercury burners are very short in your Olympus Laboratory Equipment, it might be because the power supply voltage is set improperly. Ensure that the power supply voltage is set correctly.
