In industries that have high production costs occurred when the “down time” is beginning a disorder that causes a great loss per unit time. Therefore, there must be personnel were skilled troubleshooting. Troubleshooting is a process of detecting and diagnosing all possibilities that may cause a production of equipment can not function properly. Of proven field experience, that many engineers ...

Seperti pada pengukuran arus, pengukuran tegangan listrik dengan voltmeter juga memiliki keterbatasan, tahanan dalam meter Rm membatasi kemampuan batas ukur tegangan. Menaikkan batas ukur tegangan dilakukan dengan memasang tahanan ser Rs pada meter dasar. Tahanan seri Rs akan dialiri arus sebesar Is, arus yang melalui meter Rm sebesar Im. Desain Voltmeter Bila sebuah meter D’Arsonval ditambah dengan sebuah tahanan seri ...

The more sophisticated and modern the heavy equipment units will require a large electric current. The charging system must be able to meet the current requirement under all the operating conditions of the unit and should be able to rapidly charge the battery. The main component of the charging system is the alternator and in most modern machine units with ...
