A megohmmeter is a high resistance meter dedicated to measure an ohmic value under a direct voltage of great stability. A megohmmeter is also called a high resistance tester, a megger and a high insulation tester. The Model TR1800 Digital Megohmmeter is a battery powered digital insulation resistance tester. It is designed to measure insulation resistance, continuity, voltage and to measure resistance.
