  28. Power of
  
  Inspector to require production of weight or measure or records for
  
  inspection.-
  
  1.  An
  
  Inspector may, if he has any reasonable cause to believe that an offence
  
  punishable under this Act has been, or is likely to be, committed in respect of
  
  any weight or measure or measure does not conform to the standards established
  
  by or under the Standards Act, require, at all reasonable time, the person
  
  having the custody or control of such weight or measure to produce before him
  
  for inspection every such weight or measure which--
   
  
   i.  
  
    is
  
  used by such person or is caused by such person to be used by any other person,
  
  or
   
  
   ii.  
  
    is
  
  in the possession, custody or control of such person for use, or
   
  
   iii.  
  
    is
  
  kept in or on any premises for use, in any transaction or for industrial production
  
  or for protection.
  1.  
  2.  The
  
  Inspector may also require the production of every document or other record
  
  relating to the weight or measure referred to in sub-section (1) and the person
  
  having the custody of such weight or measure shall comply with such
  
  requisition.
  3.  On
  
  inspection, whether under section 27 or under this section, the Inspector shall
  
  obliterate the stamp on--
  a.   any weight or measure
  
  which, being due for verification, has not been submitted for such
  
  verification;
  b.   any weight or measure
  
  which, since the last verification and stamping, has been repaired or
  
  re-adjusted, and does not, after such repair or re-adjustment, conform to the
  
  standards established by or under the Standards Act;
  c.   any weight or measure
  
  which does not admit of proper adjustment by reason of its being broken,
  
  indented or otherwise defective;
  d.   any weight or measure
  
  other than those specified in clause (b) or clause (c) which does not, or
  
  cannot be made to, conform to the standards established by or under the
  
  Standards Act:
  Provided that 
  
  where the Inspector is of opinion that the defect or error in such weight or
  
  measure is not such as to require immediate obliteration of the stamp, he shall
  
  serve a notice on the user of such weight or measure informing him of the
  
  defect or error found in the weight or measure and calling upon him to remove
  
  the defect or error within such time, not exceeding eight days, as he may
  
  specify, and shall--
   
  
   i.  
  
    if
  
  the user fails to remove the defect or error within that period, obliterate the
  
  stamp, or
   
  
   ii.  
  
    if
  
  the defect or error is so removed as to make the weight or measure conform to
  
  the standards established by or under the Standards Act, verify such weight or
  
  measure and put his stamp thereon.
  Explanation.-- The obliteration of
  
  the stamp on any weight or measure shall not take away or abridge the power of
  
  the Inspector to seize such weight or measure in accordance with the provisions
  
  of this Act.
