This is how we set up the electronic digital timers.
First you must know the weight of the dose you need to get the best from the coffee you are using. This can be obtained via the coffee roaster, retailer or through experimentation.
Then we set the grind size. This involves moving the adjustment collar till we get the right size particles for our chosen dose. Ignore the timer at the stage. Use your finger to remove coffee until you have your desired weight. Pull a shot through your espresso machine and as rule of thumb you want 1.6 times the weight to end up in your cup as you put into the basket. For example, if you dose 17g into your basket then you want 27g of espresso in your cup in about 26-29 seconds. Once your getting this ratio consistently, you want to set the time.
Now pay attention to the time showing on your grinder. Hit the button and weigh how much coffee was ground into your basket. Adjust the time up if not enough and down if too much. It's never going to be perfect every time but if you get a variance of 1g over 10 shots this is OK.
