2. GENERAL DESCRIPTION
2.1. INTRODUCTION
The DM-IIIS represents a new approach to the world of electrical measurement. Computer
assisted instruments such as the DM-IIIS permit an easy and fast analysis of a huge
quantity of data.
2.2.
FUNCTIONS
The DM-IIIS is able to:
 display in real time the electrical parameters of a single phase and three-phase
systems (with or without neutral wire) and the harmonic analysis of voltages and
currents.
 conduct a direct Energy measurement (without memorizing).
 memorize (pressing SAVE key) the sampled values of the Parameters present at the
instr
ument’s input generates a "Smp" record inside the instrument’s memory. It will be
possible to analyze the memorized data ONLY by transferring it to a PC.
 record simultaneously (pressing the START key after a proper setting): RMS values
of voltages, currents, corresponding harmonics, active, reactive and apparent powers,
power factors and cos

, active, reactive and apparent energies, voltage sag and surge
with 10ms resolution. It will be possible to analyze the recorded data ONLY by
transferring them to a PC.
CAUTION
Please note the difference between memorize and record. These terms
will be used repeatedly in this manual. Please focus on their definitions and
distinctions.
