5.—(1) Where an automatic discontinuous totaliser is marked with a temperature range, it shall not be used for trade in temperatures outside that range.
(2) Where an instrument bears a mark which signifies the manner and purpose of use, it shall not be used for trade in a manner or for a purpose which does not accord with that marking.
(3) An automatic discontinuous totaliser shall only be used for trade for the purpose of weighing material the value of which, expressed in units of measurement of mass, is not—
(a)less than the value of the minimum totalised load;
(b)less than the value of the minimum capacity unless processed as the last discrete load of a trade transaction; or
(c)more than the value of the maximum capacity.
(4) An automatic discontinuous totaliser shall not be used for trade in such a manner as to cause—
(a)spillage of material from the load receptor; or
(b)loading of the weighing unit above its maximum capacity.
(5) An automatic discontinuous totaliser shall not be used for trade in circumstances—
(a)in which it may be prevented from operating consistently or accurately; or
(b)which are likely prematurely to degrade its metrological characteristics.
