 电子管电性能的测量 第2部分:热丝或灯丝电流的测量
1. Scope
This document outlines conditions to be followed when measuring heater or filament current.
It does not include measuring methods.
2. Definitions
2.1 The heater current of an electronic tube or valve is defined as the current supplied to the heater.
2.2 The filament current of an electronic tube or valve is defined as the current supplied to the filament.
3. Measuring conditions
3.1 The voltage applied to the appropriate filament or heater terminals of the tube or valve shall bedefined.
3.2 No voltages shall be applied to any other elements and they may be left floating unless otherwisestated.
3.3 The current shall be measured when equilibrium is reached.
4.Precautions
4.1 The voltage used may be d.c.or a.c.,but in the case of a.c.the frequency shall be chosen so that the influence of the reactance of the heater or filament on the measured result is negligible.
4.2 The measured current shall be corrected to allow for the current drawn by the voltmeter.
1.范围
本文件概述了测量加热器或灯丝电流时应遵循的条件。
它不包括测量方法。
2.定义
2.1电子管或阀门的加热器电流定义为提供给加热器的电流。
2.2电子管或阀门的灯丝电流定义为提供给灯丝的电流。
3.测量条件
3.1应确定施加在管道或阀门的适当灯丝或加热器端子上的电压。
3.2除非另有说明，否则不得向任何其他元件施加电压，并且这些元件可以保持浮动状态。
3.3应在达到平衡时测量电流。
4.注意事项
4.1使用的电压可以是直流电压或交流电压，但在交流电压的情况下，应选择频率，使加热器或灯丝的电抗对测量结果的影响可以忽略不计。
4.2应校正测量的电流，以考虑到电压表所消耗的电流。
