Scope

This standard specifies the uniform test methods for evaluating the performance of analog calculators. This standard applies to calculators that meet the following requirements: a) For industrial process measurement and control systems; b) Input and output signals comply with the provisions of GB/T 777 or GB/T 3369.1 or GB/T 3369.2; c) The mode of transportation is plus Subtraction, multiplication and division or square root; d) Used under normal working conditions. For calculators whose input and output are other analog signals or calculators of other modes of transportation (such as ratio calculation), it can also be used by reference. For calculators used under special working conditions and other types, the applicable tests in the standard and the additional tests required can be selected according to the specific conditions of the calculators.
