What is BS 7194- Electronic measuring instruments about?
BS 7194 is an International Standard that discusses the aspects of electronic measuring instruments with a digital display.
BS 7194 specifies requirements for the performance of electronic measuring instruments with a digital display intended for measuring analogue quantities of voltage and/or current.
BS 7194 applies to instruments for indicating other quantities including non-electrical quantities, provided that the relationship between the indicated quantity and the measurand is known.
BS 7194 also applies to self-contained instruments having their own enclosure, terminals, etc., and to instruments for fitting in an enclosure where the enclosure is not provided by the supplier of the instrument [original equipment manufacturer (OEM) instruments].
BS 7194 applies only to instruments measuring current and voltage at DC and an AC at distribution system frequencies and their harmonics. BS 7194 applies to the digital parts of an instrument having a combined analogue/digital display.
Note 1: BS 7194 does not specify requirements concerning dimensions of instruments and does not apply to instruments having a digital or coded measure input.
Note 2: BS 7194 does not apply to special purpose instruments which are covered by their own British Standards and contains no requirements for the visibility of the display.
Note 3: BS 7194 also does not apply to accessories.
Who is BS 7194- Electronic measuring instruments for?
BS 7194 on electronic measuring instruments is relevant to:
- Manufacturers and designers of electronic measuring instruments
- Suppliers and exporters of electronic measuring instruments
- Electrical engineers/ Electronic engineers
- Regulatory authorities
- Testing authorities
Why should you use BS 7194- Electronic measuring instruments?
An electronic measuring instrument is a measuring instrument that is intended to measure an electrical or non-electrical measure using electronic means.
BS 7194 guides you in specifying standard direct-current and low-frequency electronic measuring instruments with a digital display. It assists with influence quantity, reference conditions, nominal range of use, and preconditioning.
BS 7194 gives class indices that are selected from 1, 2, 5 sequences or a decimal multiple or a submultiple thereof. BS 7194 elaborates on the nominal range of use and variations.
BS 7194 presents the users with the conditions for the determination of variations in the electronic measuring instruments. The procurement of the electrical and mechanical requirements, as well as the construction requirements given in BS 7194, helps the users to manufacture good quality, efficient and reliable electronic measuring instruments.
BS 7194 provides general information for markings and symbols that enhances the quality of the product.
Overall, BS 7194 is useful as it specifies the direct-current and low-frequency electronic measuring instruments that can be beneficial for your business and can also help you to expand your business globally.
