This standard specifies the type, basic parameters and dimensions, technical requirements, test methods, inspection rules and storage of amplifiers for automatic balancing display instruments. This standard applies to transistor amplifiers for automatic balancing display instruments for analog signals (power range greater than or equal to 10mV dc). This standard only applies to amplifiers whose input is a DC signal and whose output is connected to an AC servo motor. This standard does not apply to amplifiers whose input is AC signals. Other types of amplifiers used in automatic balance display instruments may refer to the relevant provisions of this standard.
