14. Instruments for direct sales to the public shall show essential information about the weighing operation and, in the case of price-indicating instruments, shall clearly show the customer the price calculation of the product to be purchased.
The price to pay, if indicated, shall be accurate.
Price-computing instruments shall display the essential indications long enough for the customer to read them properly. Price-computing instruments may perform functions other than per-article weighing and price computation only if all indications related to all transactions are printed clearly, unambiguously and conveniently arranged on a ticket or label for the customer.
Instruments shall bear no characteristics that can cause, directly or indirectly, indications whose interpretation is not easy or straightforward.
Instruments shall safeguard customers against incorrect sales transactions due to their malfunctioning.
Auxiliary indicating devices and extended indicating devices are not permitted.
Supplementary devices are permitted only if they cannot lead to fraudulent use.
Instruments similar to those normally used for direct sales to the public which do not satisfy the requirements of this section must carry near to the display the indelible marking “Not to be used for direct sale to the public”.
