    But John, please don't start the rumor that these scales are
not accurate, you'll have people tossing and turning all through
the night:^) 

G’day; perhaps I could have put things a little better - in fact
when I wrote my thoughts on electronic scales, my so-called 'mind’
went on a little walkabout, for I thought that I was writing direct
to ‘Calgang,’ and I hadn’t intended it all to become public
property, dammit!!

However, my real point was that unless e-scales are guaranteed to
a certain accuracy, one should be careful about how and what they
are used for. If one buys a weighing device sold specifically for
weighing precious materials, then the maker’s guarantee (if heshe
is a reputable person/firm) should be sufficient. Even so, I
would be a bit sceptical of any figure which oscillates. I
certainly would not use a coin-of-the-realm to calibrate or to
weigh a precious material against. A freshly minted coin; maybe?
I still would need to calibrate that first! Cheers,

Hello John Burgess- Yes, I agree about the scales- personally, I
use the test weights that come with the scale or a set from an old
diamond scale, the counterweights, I mean, to calibrate. Actually
any mis calibration shows up quite soon as the weight is generally
an identifying characteristic of the stone and is on the envelope
and is what you’re weighing against. Any discrepancy can only be,
the wrong stone in the envelope and visa-versa, or your scale is
off. The second stone you check is going to tell you which, right?
This was a trick that someone told me in the absence of any proper
counterweights, but now I’m going to have to check after Jan’s
4.89gr. Certainly not close enough for this business, right?
Regards- RL


To Our U.S. Subscribers, Although the Law varies from locality to
locality, very often one must use a weighing device that has been
"sealed". A “sealed” scale is one where an official Commissioner
of Weights and Measures has weighed an nearly exactly calibrated
brass (or some other substance) weight on the said scale and found
it to be within some legally subscribed tolerance of accuracy.
Then the Commissioner will apply some sort of “sticker” or raised
seal to the scale verifying its accuracy. One frequently sees
these “seals” on gas station pumps for example. There can be
severe fines for using a scale that has not been sealed for
commercial transactions. 20 If you find yourself in such
circumstances, you should contact your local town hall or county
government office and inquire about having your scale(s) sealed.
There is usually some nominal fee involved, something like $15-20.
So, stay on the straight and narrow and have your scales sealed!
