Amprobe DM-III S
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.

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 instrument’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.
