How to Calibrate then test your Digital Scale.

OK, so I found this super great awesome Digital Scale on that can weigh my fine gold, flakes and nuggets for only $9.29, but I forgot to buy the 100 gram weight  ($3.42) to calibrate.

In the mean time I was able to use some 1 Troy OZ Silver Maple Leafs (3 Maple Leafs + 1 Cdn quarter and 1 Cdn penny) as weight to add up to 100.06 grams. After Calibrating, using the instructions on the lid of my super, great, awesome Digital Scale I then checked several coins just to make sure I was getting good readings. And indeed I am.

Check these out:

US Dime = 2.26 g                                  Cdn Dime = 1.74 g             Cdn quarter = 4.44g

Now, I should be able to determine if that tiny flake of gold is .25 of a gram or not !

  • Awesome TARE function to determine the net weight of any product by subtracting the weight of your vial.
  •  Easy touch buttons, large size digits, and stark contrast LCD blue backlight display, make the measurements easy to read. The scale's platform measures 2.5 x 3.0 inches.
  • Measurements - Includes all the necessary unit measurements for easy weight translations: gram, ounces, grain, and carat. Set the scale to your desired measurements by pressing the MODE button
  • Accuracy - Weighs a capacity of 100g in increments of 0.01g. Manufactured with high precision sensors to ensure accurate weight readings. 

Notes on Canadian Coins: 

Each Canadian coin in circulation weighs differently based on size and content. According to the Canadian Numismatic Publishing Institute, there are nine coins in circulation. Each coin has different dimensions and is composed of different metals, making each unique.

The nine coins, their weights in grams and their compositions are:
  • One cent, 2.35 grams, 0.94 steel 0.015 nickel 0.045 copper plating
  • Five cents, 3.95 grams, 0.945 steel 0.035 copper 0.02 nickel plating
  • Ten cents, 1.75 grams, 0.92 steel 0.055 copper 0.025 nickel plating
  • Twenty-five cents, 4.4 grams, 0.94 steel 0.038 copper 0.022 nickel plating
  • Fifty cents, 6.9 grams, 0.9315 steel 0.0475 copper 0.021 nickel plating
  • One dollar, 7.0 grams, 0.915 nickel 0.085 bronze plating
  • Two dollars, 7.3 grams, 0.69 nickel 0.29 copper 0.02 aluminum
  • Five dollars, 8.36 grams, 0.900 gold 0.100 copper
  • Ten dollars, 16.72 grams, 0.900 gold 0.100 copper
On May 4, 2012, Canada minted its last penny. In early 2013, the Royal Canadian Mint began to collect and recycle them because the cost to mint one penny was 1.6 cents.
