I like to use a timer for print processing that I can program multiple times and sequence through them. Currently, I have a Spiratone Darkroom Director that has 9 channels. However, one has to use all nine! So, I program three times, um, three times. I.e.: 1-2-3; then the same in 4-5-6; amd again in 7-8-9. Fortunately, the timer will keep recycling through the 9 channels until it's turned off. It works, but it's a lot of programming for three values. I tried a Gralab 900, but wasn't satisfied with it for unrelated reasons. A local chap has a Kearsarge 403 for sale. It has 10 programmable channels, but that's all I know. Can I program 3 or 4 of the 10, leave the others blank, and sequence through them AND then repeat without having to re-program each time? Hope that's clear ... Thanks!
