Introduction

The purpose of this user guide is to describe the use and capabilities of the
XT560 Digital Milliohmmeter.

Scope

The XT560 Digital Milliohmmeter is a dedicated, fully automatic instrument
that selects the optimal test current, from 100nA to 100mA DC to accurately

measure resistances from 10μΩ to 33MΩ. The XT560 will auto range

between 9 ranges, or can be manually set to a fixed range. The XT560
includes a set of Kelvin test clip leads for making four-terminal
measurements.

Introduction 8

The XT560 is ideal for measuring wiring or cable resistances, windings of
motors or generators, lamp filaments, cable splices, wire-to-terminal
resistances, heating elements, contact resistance of breakers or switches,
connector quality/resistance, fuse resistances, transformers, and grounding
connections.

Features

The XT560 Digital Milliohmmeter’s features include the following—

Maximum Display of 33000
Power Supply 90VAC to 260VAC, 50/60Hz
Wide Measurement Range: From 10μΩ resolution to 30MΩ full

scale
