<li>갈바노미터 보호용 다이오드 (galvanometer protection diode)<br />
<ol><br />
<li>원리<br />
<ol><br />
<li>이 갈바노미터 평균 저항이 2k오옴. 약 0.2mA일 때 FS라면, 0.4V 걸린다.<br />
<li>다이오드 V-I 그래프를 볼 때, 0.4V일 때 0.01mA 흐른다.<br />
<li>즉, FS에서 갈바노미터로 들어가는 전류중에서 1/20 만큼 다이오드로 흐른다.<br />
<li>FS에(에 근접할수록) 5% 오차가 발생된다. 이를 고려하여 비선형으로 눈금 인쇄를 해야 한다.<br />
<li>그렇지 않으면, 이 미터에 붙여야할 다이오드는 Vf가 더 높은 것을 사용해야 한다.<br />
