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:
Voltage anomoalies detection (manual selection of range)
Voltage
Time
Current measurement (using external transducer)
Minimal Current measurable is equal to 0.5% of Clamp Full Scale
Power measurement (cosf: 0.5c ヨ 0.5i)
Cosf measurement
Harmonics measurement
Voltage
The voltage harmonics will be null under the following threshold:
- DC: if <1V or <2% of 1st harmonic
- 1st harmonic: if <2V
- 2nd divided by 49th: if <1V or <2% 1st harmonic
Current
The voltage harmonics will be null under the following threshold:
- DC: if <2% of 1st harmonic or <0,2% of clamp full scale
- 1st harmonic: if < 0,2% of clamp full scale
- 2nd Divided by 49th: if <2% 1st harmonic or <0,2% of clamp full scale
Setting the FLEX option the DC componenet will be ignored
Frequency measurement
Instrument set to 50Hz
Instrument set to 60Hz

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メs input generates a "Smp" record inside the instrumentメ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.
