I only have 2 cups of coffe a day but insist that it's fresh and strong. I pour the hot water thru a coffee-filled #2 cone filter held in a ceramic holder, a lid on top to keep things hot for the 1 3/4 minute it takes to go through. Yummmmmy!
In the morning for my 8 oz cup I use a well-rounded Tbsp of grounds -- plus a 1/4 of that on top to make it robust.
Enter my new digital scale. Supposedly accuracy to +/- 1 gram, I couldn't wait to try it this morning. I decided to convert my Tbsp quantity to grams and decided on 9 grams for a starter, figuring I would adjust that value depending on how strong or weak the concoction was.
Well, at first blush, I was impressed. Put the ceramic holder with filter on the scale, turn the unit on and the value is zero (0) -- perfect. The holder's weight becomes the tare and is automatically subtracted. Next, place my usual Tablespoon fill of grounds into the filter, check it out. Not bad -- 8 grams. Time to put a bit more onto the pile. Ooops! 10 grams, 1 too many. Not a problem, says I. Scrape a tad back into the spoon. Nothing changes on the readout. A bit more. Nothing again. By the time the scale reading changes to my goal of 9, I've removed some 2/3 of the original pile. My ballpark math says that based on what I subtracted, the scale should read closer to 3 instead of 9.
Go through the above scenario again but see no improvement. It appears to behave okay if all I do is add. However, in subtraction, the unit sensor seems flawed.
Am I expecting too much from one of these digital kitchen scales? Or do I have a lemon? Yes, it's a cheapo unit that I bought and I'm willing to fork out a few more bucks for something that works.
