Introduction

Fully automatic measurement systems have been widely used in manufacturing testing, research and various fields involving measurement. Measurement automation is widely implemented Data sharing, inter-instrument communication and remote measurement control. Multifunctional data acquisition equipment (DAQ) meets these measurement needs. DAQ Relying on standard computer technology enables measurement system developers to make full use of open computer standards. The measurements made by DAQ are Accurate and traceable. To ensure measurement integrity, not only the standards for the measurement hardware, but also the software system for the calibration hardware Set standards. Performance and calibration method of data acquisition software

1 Scope

This standard specifies the performance characteristics and calibration methods of data acquisition software. This standard covers. ---DAQ manufacturers provide minimum specifications that describe the performance of DAQ's analog-to-digital conversion module (ADM); ---Standard test strategy used to verify the minimum specification requirements; ---Minimum calibration information required by ADM stored on DAQ; ---The minimum calibration software requirements for external calibration and self-calibration of DAQ ADM. This standard applies to DAQ for low-frequency signal conversion. Examples. low-frequency signals applied in equipment control, vibration measurement, vibration diagnosis, acoustics, ultrasonic measurement, temperature measurement, pressure measurement, power electronics measurement, etc. Number conversion.
