RIGHT! that's it... i've had just about enough of this thing....
It's a polysales automatic meter/timer - i've got it wired up to my ancient enlarger and safe lamp.. not sure if i've wired it correctly...
anyway, the enlarger bulb comes on when you switch the unit on (and never goes out)... the timing durations seem to be accurate, but they don't control the enlarger!
also the safe light comes on when you turn the selector switch to 'time'.

you might realize that I don't know what i'm doing. could anybody provide some info on how to work this thing?

thanks in advance
