Methods of evaluating the performance of electrical and pneumatic analogue chart recorders for use in industrial-process control systems HD 504 S1:1988

Scope

This standard provides methods for determining the performance of all electrical and pneumatic analogue chart recorders operating from a standardized signal which may be used in process control - It is intended that continuous and dotted line traces multiple-pen and multiple-channel instruments should be covered - Sometests shall not apply to all instruments and additional tests may be required for certain types of recorders
