Ilford Multigrade Head Setup
I have been reading the manual of the Ilford 500H Head and they advise that when first setting up and when changing a bulb, that a couple of tests are performed to determine 1. which lamp is the brightest and 2. where the program switch setting should be set.
I tend to set up equipment as per the instructions, so I will do this when I get the chance, but I was wondering if people here do this and if so does it make any significant difference to operation. Neil |

When I first got involved with the 500H I used to fiddle with the program switch but in the end I decided not to bother as I found the difference between bulbs (even with a new and old fitted) was negligible. I would set the switch as recommended and start off with two new bulbs and take it from there.

I bought mine S/H from Odyssey and it came set on 4. I've fiddled with it at times but have left in on 4.

It has been a long time since I was clued up on what this program switch actually is used for. However, I have vague recall that it would be handy in a commercial lab if a bulb was to fail say half way through doing a run of 100 of the same print. Getting back to same bulb balance as was before would in these circumstances save a lot of time.

This is what my MG manual says of the program switch; 1 balanced lamps (normal setting) 2 increase green light by 10% 3 increase green light by 20% 4 increase green light by 30% 5 increase green light by 40% It goes on to say, "1. If the density is high at the low contrast end, interchange the lamps and proceed to 2 as necessary. 2. If the density is low at the low contrast end, optimum balance and density over the contrast range can be obtained by selecting a higher number in the range 2-5 on the program switch".

Trevor, yes it would be very noticeable if you were doing a run of the same and a lamp goes on the blink. I have my switch set to 1 and I just leave it there now, but of course I am only doing one or two prints and no long runs. Interesting to know though that all this is built into the kit. Neil.
