IC Enlarger Timer projector lens 6 DG HSM lens isIt's much harder to explain the IC Enlarger Timer than it is to use it: there are three dials, marked in 10, 1, and 0. 1s increments, and you set your desired time by turning each dial to add up to the appropriate number. For example, if you wanted to set a time of 13. 5 seconds, you'd set the first dial to 10, the second dial to 3, and the third dial to 0. 5. It's math! Anyway, not sure if I made that more or less confusing, but trust me, it's easy
