Vario Stop Clock Timer problem

davidbuttts · Jan 16, 2008

I am looking for someone who uses an Aristo VCL 4500 light source and a Vario Stop clock timer. I am having trouble adjusting the speeds of the two lights. I am new to APUG and still trying to find my way around the site.

You should probably go to the darkroom equipment part of the forum:

(there was a url link here which no longer exists)

I do have that enlarger head but I don't know what a Vario Stop clock timer is.

Welcome to APUG David.

I use an Aristo 1212 cold light with a Vario Stop Clock Timer and am very happy. That won't help you much since it is a single light. R. H. Designs is a sponsor here and I am sure would be more than willing to help. Here is a link to their contact page. Pick the method of contact that works best for you and try them.

Hi John, Thanks for your reply. I did try contacting RH Designs and they understood the problem as I described but they did not feel that it was a problem and that I should just print with the crazy times. They did suggest contacting someone on APUG and hence my request. It would still be nice to find someone using the identical configuration that I am using.

Not having access to a VCL4500 myself it's difficult to offer a definitive answer, however I do know from personal experience that the Zone VI VC head together with both the Vario and the Zone VI Compensating Timer exhibits similar behaviour - the "seconds" are quite a bit longer with only the blue tube illuminated vs only the green tube. That's why I don't think it's a problem - it simply suggests that the blue tube is dimmer than the green one. Provided the sensor is "looking" at the diffuser and not the tubes directly, everything should work as intended.

Hi Richard,

Thanks for your information. I will go ahead and try printing and see how it all works out.
