当使用电学仪器进行测量时,为了保证测量精度,符合检定规程,提高工作效率,必须正确的选择检流计。下面就有关检流计的合理选择问题论述如下。一、检流计的灵敏度决定着测量装置的灵敏度对任何测量装置来说灵敏度是一个重要指标。它决定着该装置的测量精度。假定有一个电测量装置,X是被测量接在未知端钮上,电计端钮上接有检流计。当X=X_0时电路平衡,检流计指零;当被测量X有一个微小的变化Δx时,平衡就破坏,检流计的指 When using electrical instruments for measurement, in order to ensure measurement accuracy, in line with test procedures to improve work efficiency, the correct choice of galvanometer. The following about the reasonable choice of galvanometer problems are discussed below. First, the sensitivity of the galvanometer determines the sensitivity of the measuring device Sensitivity of any measuring device is an important indicator. It determines the measurement accuracy of the device. Assuming there is an electrical measuring device, X is measured connected to the unknown end button, galvanometer terminal connected to the galvanometer. When X = X_0 circuit balance, galvanometer refers to zero; when measured X has a small change Δx, the balance is destroyed, galvanometer finger
