1.1<\/b> This British Standard specifies requirements for indirect-acting electrical instruments using a null balance method which need an auxiliary electrical power supply.<\/p>\n

These instruments may indicate the value of the measured quantity or record the value of the measured quantity as a function of time. Instruments may combine both these functions.<\/p>\n

1.2<\/b> This standard also applies to electrically operated measuring equipments, provided that the electrically operated measuring instrument (receiver) only is considered and that the relationship between the non-electrical and the electrical quantity is known.<\/p>\n

1.3<\/b> This standard does not apply to:<\/p>\n

    \n
  1. devices comprising a direct-acting indicating and\/or recording instrument energized by a measuring amplifier;<\/li>\n
  2. electrically operated measuring equipment when the relationship between the non-electrical and the electrical quantity is not known;<\/li>\n
  3. control apparatus even though it includes indicating or recording instruments;<\/li>\n
  4. indirect-acting electrical instruments in which the measured quantity is presented in the form of digits, codes, punched cards, etc.;<\/li>\n
  5. position follower instruments;<\/li>\n
  6. recording instruments in which the chart movement is a function of a quantity other than time;<\/li>\n
  7. integrating instruments or auxiliary integrating devices incorporated in instruments within the scope of this standard.<\/li>\n<\/ol>\n

    1.4<\/b> This standard does not contain requirements for protection against environmental conditions.<\/p>\n

    1.5<\/b> This standard does not specify requirements concerning dimensions of instruments or detailed requirements concerning terminal markings and diagrams of connection.<\/p>\n
