- Scope
- This standard specifies a unified test method for the performance evaluation of analog calculators. This standard applies to calculators that meet the following requirements: a) For use in industrial process measurement and control systems; b) Input and output signal symbols GB/T 777 "Analog Pneumatic Signals for Industrial Automation Instruments" or GB/T 3369 "For Industrial Automation Instruments" Analog DC Current Signal" or GB/T 3370 "Analog DC Voltage Signal for Industrial Automation Instruments"; c) The operation method is addition, subtraction, multiplication, division or square root; d) Use under general working conditions. It can also be used as a reference for calculators whose input and output are other analog signals or calculators with other calculation methods (such as the following value calculation). For calculators used under special working conditions and other types of calculators, the applicable tests in the standard and the required additional tests can be selected according to the specific conditions of the calculator.
