Nocon f-stop Timer

[Richard Lee]

I've recently become the proud owner of a Nocon enlarger timer but have been unable to get it to calculate/display + or - times in quarter stop increments separately from the base exposure. So far, any sequence of button pressing simply adds or subtracts to give a new total base time.



I'm assuming it shouldn't be necessary to refer to the chart and enter burn/dodge times manually. I would be very grateful for any enlightenment, please.

Regards,

Richard

Unfortunately the man who thought this device up has passed away, although there may be someone out there with instructions.

There is another way that you may possibly get what you are looking for. There is a company called RH Designs in UK, website www.rhdesigns.co.uk.

The owner, Dr Richard Ross designed and makes one very similar so if you make contact via E mail he may be able to help. He is on the point of retirement and has sold the rights to another company but as far as I know he is still open for business - just.

I'd be surprised if someone here doesn't have one with instructions but failing that try Butkus who seems to have instructions for almost everything

I'm sorry I can not help but can you upload more pictures of it? I always wanted to see it.

[Richard Lee]

Many thanks for your input. I will certainly follow-up these two leads.

Incidentally, the manufacturer Bowens, claim they have no record of this item - much less, a set of instructions!

Hi Richard

I have a set of instructions for the model you have. I will scan them in tomorrow and try and upload or email to you. If I understand correctly. If, for example, your base exposure is 10 sec and you press -1 stop, the timer will count up to 5 secs. By pressing the calc button it will show this. If you then pressed +1/4 with 'Calc' button on it then shows 11.9 sec which is the base, 10 secs, + the 1/4 stop. Your base time is always set in the timer via the keys under the display and stored by the 'Ent' button. Personally I have found this timer to be one of the best f / stop timers. I have never tried the RH stop clock but do have the Analyser. I find that good but it has to many secondary functions which confuses my simple mind.

This really is music to my ears - I'm sincerely grateful.

Guided by your explanation then; if I want to burn an area for an additional 1/2 stop above the base, 10 sec:
10 sec>ENT> -1/2 stop = 7.1 sec... Hmm, given that the sequence is 10, 11.9, 14.1, etc., shouldn't the difference be 4.1 sec? Hey, and you thought you had a 'simple mind'!

Hi Richard

I have posted them in the manuals over on FADU. It won't let me upload on here as the file size is to big? i will PM them to you if I can. If you want to burn for 1/2 stop over the 10 seconds base you press +1/2. this then gives you 14.1. The timer when activated will do your base exposer and turn off. Then to do your burn you hit the increase button and the timer will count up the extra 4.1 secs. If you hit the initial button again it is like resetting it and it will count up from 10 secs again. if you have any problems let me know and I will try and help you out.

[Stephen Weston]
