IS 13875 : Part 1 : 1993 Digital measuring instruments for measurement & control: Part 1 General specifications concerning terms, tests & data sheet details

1 Scope

1.1 This standard (Part 1) applies to digital electronicmeasuring instruments (hereinafter called measuring instruments)used for measurement of physical quantities, which indicate thevalues measured by numerical and/or digital display. This includesmeasuring instruments for measuring:

- analog quantities (for example, voltmeters, ohmmeters,temperature measuring instruments)

- digital quantities (for example, eventmeters), and

- time-related quantities (for example, frequency meters, speedindicators).

Combinations of above-mentioned measuring instruments are alsocovered by the scope of this standard.

1.2 This standard also applies to measuring instruments whichcombine (link) various measured quantities, each independent of theother, or several measurement values of the same quantity (forexample wattmeters, phase meters, differential pressure meters,mean value meters), as well as to externally controlled measuringinstruments.
