An electro mechanical type voltmeter is much robust in construction than that of an electronic type. Digital meters designed to measure quantities other than voltage are, in fact, digital voltmeters that contain appropriate electrical circuits to convert current or resistance measurement signals into voltage signals. These are of like moving iron, moving coil, electrostatic types of voltmeters. We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads. The block diagram showing a digital voltmeter of successive approximation type is shown in Figure. Digital Voltmeter (DVM). Analog voltmeters generally contain a dial with a needle moving over it according to the measure and hence displaying the value of the same. f o n t H e r m a n _ 3 e _ P P T � 8BIM U8BIM � p T P n@ � ���� JFIF H H �� Adobe d� �� � 8BIM� H /ff lff /ff ��� 2 Z 5 - 8BIM� p ����������������������� ����������������������� ����������������������� ����������������������� 8BIM 8BIM 8BIM @ @ ?� 8BIM 8BIM � � C h g .
