This part of IEC 60770 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.
For the method of inspection and routine testing of the intelligent transmitters see
IEC 60770-3.
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 and/or IEC 60770-3, respectively for analogue or intelligent
transmitters 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.
