How about another THR myth confirmation/busting? To benefit THR members and guests, I have come up with a digital scale accuracy challenge.
For years, there have been discussions as to the accuracy and reliability of digital scales. Over the years, I have used 1/4"x1/4" pieces of paper cut from copy paper to test sensitivity of scales. Both of my Ohaus 10-10 beam scales will detect one piece of paper yet the digital scales I have tested won't always show detection until 2-3 pieces of paper were placed and then they would read .1 gr (Depending on the paper thickness, pieces should weigh around .03-.05 gr and take 2-3 pieces to show .1 gr reading).
So this is the challenge - Use thinner/cheaper plain copy paper or newspaper and cut 1/4"x1/4" pieces and see what your digital scale readings are. If you can, it would help to post:
- Brand/model of digital scale and price paid
- Paper used: copy paper or newspaper
- Ambient temperature
- Resolution of scale in grains "gr" not grams "g"
- If you have check weights, readings after calibration of scale and check weights below 5 grains
- Number of paper pieces when scale showed detection/reading
- 5/10 sample readings to show consistency using 2-3 pieces of paper (whichever number your digital scale is able to detect)
Thank you and looking forward to the results.
