This part of IEC 60770 is applicable to transmitters@ which have either a standard analogue electric current output signal or a standard pneumatic output signal in accordance with IEC 60381-1 or IEC 60382. The tests detailed herein may be applied to transmitters which have other output signals@ provided that due allowance is made for such differences. For certain types of transmitters@ where the sensor is an integral part@ other specific IEC or ISO standards may need to be consulted (e.g. for chemical analyzers@ flow-meters@ etc.) This standard is intended to provide technical methods for inspection and routine testing of transmitters@ for instance@ for acceptance tests or after repair. For a full evaluation@ IEC 60770-1 shall be used. Quantitative criteria for acceptable performance should be established by agreement between manufacturer and user. By agreement the tests need not be carried out by an accredited laboratory.?
