变差是指示仪表的重要问题之一,尤其是垂直使用微安量限(且对内阻有要求)的磁电系仪表变差问题尤为突出。我们在试制30μA、3500Ω,200μA、80Ω这一类的垂直、水平通用1.0级仪表中对变差作了初步的分析研究,下面谈谈我们的初步体会。一、轴尖支撑指示仪表的变差轴尖支撑指示仪表的变差有两个突出的特点:1.水平轴的变差远远大于垂直轴的变差;2.变差在全偏转范围内各点上呈现有规则的非
Deterioration is one of the important problems in indicating the instrument, especially the problem of deterioration of the magnetoelectric instrument which is vertically limited by the microampere limit (and has the requirement of internal resistance). We are in the trial of 30μA, 3500Ω, 200μA, 80Ω this type of vertical, horizontal general grade 1.0 instrument made a preliminary analysis of the deterioration, let’s talk about our initial experience. First, the shaft support indicator instrument variation Axis shaft support instrumentation variation has two outstanding features: 1. The horizontal axis of the variation is much greater than the vertical axis of variation; 2. Variation in the range of full deflection Each point shows a regular non-
