IEC 60770-2:2010 is applicable to transmitters, which have either a standard analogue electric current output signal or a standard pneumatic output analogue 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. It 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 and/or IEC 60770-3, respectively for analogue or intelligent transmitters shall be used. This third edition cancels and replaces the second edition published in 2003 and constitutes a technical revision. The significant technical change with respect to the previous edition is: the sequence in content has been reordered in Clause 5. This publication is to be read in conjunction with IEC 61298-1:2008, IEC 61298-2:2008, IEC 61298-3:2008 and IEC 61298-4:2008.
