Introduction Amprobe MO-100 Milliohm Meter

Diagnose motor, generators and transformers for problems with confidence using the Amprobe MO-100 Digital Milliohm Meter. Quickly check windings for opens or shorts in motors, generators and transformers, wire-to-wire connection resistances in heating elements and contact resistance in critical electrical connections.

The Amprobe MO-100 digital milliohm meter measures resistance up to 2,000 ohms in automotive, industrial, and heating, ventilation, and air-conditioning (HVAC) applications on a LCD screen. The meter’s hold function keeps a reading on the display, even after meter is disconnected.

It has four input terminals for taking four-wire resistance measurements to ensure accuracy. It has a minimum resolution of 100 microohms for measuring small amounts of resistance. The meter offers a choice of three test currents for more precise readings. Over-temperature and over-voltage warnings help prevent damage to the meter. The meter comes with four test leads with alligator clips that provide hands-free connection to conductors up to 0.67-inch (17-millimeter) in diameter. The test leads have a shrouded plug that helps protect against shock if the leads are accidentally pulled out of the meter during use.
