Question about Zeiss Science & Laboratory

Open Question

I have a Zeiss/Humphrey FDT (frequency doubling technique) visual field analyzer. We're pretty sure that the transformer is out. Zeiss won't share the specs on this discontinued item. Does anyone know what the specs are? Thanks!

How do I hook my external laser printer to my humphrey 740?


In the user manual they list some compatible printers that have a 25 pin parallel connector. We use Lexmark Optra E312L with good results. Once you hook it up, you have to go into one of the setup menus to port it over. The user guide tells the procedure.

Why does my zeiss humphrey visual field machine keep shutting down?


Sounds like a heat, thermal issue. You may have a non- functioning cooling fan somewhere inside. There are several of them so don't be fooled if you hear one of them running. Same issue happens with CPUs on PC computers. Will suddenly shut off if too hot.

Zeiss humphrey system startup state 19


I believe "state 19" is a weak main illumination bulb. Not sure if it's the same on your 740, but that's what the problem was with our 750i. Even though the bulb appears to be working, they dim over time and won't pass the start up calibration checks. On ours, there is a round access panel on top of the unit to service this bulb. Just be careful removing the bulb and don't bump any of the clear optical wheels. Part # 2660021106082 (for 750i. not sure about 740) Call Zeiss to confirm. Realize this is an old post so info is for future readers.
