Binary/analog inputs and
inputs for analog DC
measurement
The ELT-1 option enables the CMC 356 to measure analog signals:
• Analog DC inputs (+/-10V and either +/-1mA or +/-20mA) for basic
transducer testing with the test module QuickCMC.
• Basic voltage and current measurements with up to three of the 10
analog measurement inputs (restricted EnerLyzer mode).
In addition, the Test Universe module EnerLyzer provides the following
functionality:
• Simultaneous measurement of up to 10 voltages and/or currents.
• Evaluation of DC components (DC voltages or DC currents).
• Real-time indication of effective values (true RMS) for all measurement
signals.
• Peak values indication (U
peak
, I
peak
,...).
• Phase angles with reference to a given input signal.
• Real-time calculation of apparent, reactive, and active power (in any
configuration).
• Frequency and spectrum indication (harmonic diagrams) of periodic
signals.
• Capturing of transient input signals with different sampling rates.
• Different triggering options for transient signal capturing (basic triggers
and power quality triggers).
• Trend Recording: Measurement of RMS current, RMS voltage,
frequency, phase, active, apparent and reactive power and power factor
over long periods of time (up to 4 million samples possible).
