描述

The MO-100 is a portable battery-powered milliohm meter designed to diagnose potential failures by measuring low resistance values in motors, generators, transformers, and critical electrical connections. It features accurate four-terminal measurement capability down to 100 microohms without requiring test lead resistance compensation, with five measurement ranges from 200.0 milliohms to 2000 ohms and a minimum resolution of 100 microohms. The meter employs three selectable test currents (1 mA, 10 mA, and 100 mA) with over-temperature protection and over-voltage protection, delivering measurement accuracy of ±0.5% of reading ±2 digits across the operating temperature range of -15°C to 55°C. Additional features include a large LCD display, AUTO-HOLD and AUTO-OFF functions, potential and current lead resistance checks, and an O-ring sealed enclosure for durability. The MO-100 is ideal for field technicians and maintenance personnel who need to quickly verify winding integrity, connection resistances, and heating element continuity in industrial and electrical applications.
