Heathkit PT-1500 darkroom timer manual.

[MrBrowning]

Does anyone have a manual for a Heathkit PT-1500 darkroom timer? I was going through my box of stuff and found the timer. Was hoping someone here might be able to help.

Ah, Heathkit.... I built two of their color TV kits. Excellent products.

I may have one here. What do you need from it. It is rather hefty describing assembly, but the operation is rather straightforward and that section is rather skimpy IIRC.

I too have fond memories of Heathkit, having used a Heathkit computer for data acquisition in my Ph.D.

I have the computer and disk drives, an Oscilloscope and several other items.

Hi PE, we have a Heathkit PT 1500 timer and we would like to know how to make it repeat the same amount of time.
thanks. J.

Hi PE. I'm sorry I missed your post way back then. I was looking for how to repeat the time from exposure to exposure without having to set it each time. Just as bluejeh is.

On the one I have there are 2 dials on which you set the time. Once set, you simply press the expose button and it fires for that time, over and over. So, unless there are different models, IDK how else to do it or how there could be a problem.

Mine has no dials on it. You have to enter the time on the number pad after each use. FWIW here is a photo (not mine) of a timer like the one I own.

Ok, mine has the same type case, and probably is the same size, but everything is dials and pushbuttons. I'll have to check the #. I may have gotten it wrong.

Sorry.

No worries. Thanks.

Mine has the dials and runs 10% fast. Is there anything in the manual about making adjustments?
