3.5 Monitoring the test substances
The metrology features of the balance and any possible available adjusting weight
must be checked at regular intervals within the scope of quality assurance. For this
purpose, the responsible user must define a suitable interval as well as the nature
and scope of this check. Information is available on KERN’s home page
with regard to the monitoring of balance test substances and the test
weights required for this. Test weights and balances can be adjusted quickly and at a
reasonable price at KERN’s accredited DKD (Deutscher Kalibrierdienst) calibration
laboratory (return to national standard).
In the case of the scales for weighing people provided with the scale to determine a
body size, it is recommended to carry out the check of its measuring accuracy be-
cause determination of the human body size is always connected with a very large
inaccuracy.
