(ii)to take such measurements and photographs and make such recordings as the enforcement officer considers necessary for the purpose of any such examination or investigation.
(d)as regards any premises which an enforcement officer has power to enter under sub-paragraph (a), to direct that those premises or any part of them, or anything in them, be left undisturbed (whether generally or in particular respects) for so long as is reasonably necessary for the purpose of examination or investigation under sub-paragraph (c);
(e)to take any samples, or cause samples to be taken, of any articles or substances found in or on any premises which an enforcement officer has power to enter under sub-paragraph (a), and to cause any such articles or substance to be analysed or tested;

any entry onto those premises by virtue of paragraph (1)(a) may only be effected under the authority of a warrant.
