Technical Data676.10 Option ELT-1Figure 6-18:Binary/analog inputs andinputs for analog DCmeasurementThe ELT-1 option enables the CMC 356 to measure analog signals:• Analog DC inputs (+/-10V and either +/-1mA or +/-20mA) for basictransducer testing with the test module QuickCMC.• Basic voltage and current measurements with up to three of the 10analog measurement inputs (restricted EnerLyzer mode).In addition, the Test Universe module EnerLyzer provides the followingfunctionality:• 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 measurementsignals.• 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 anyconfiguration).• Frequency and spectrum indication (harmonic diagrams) of periodicsignals.• Capturing of transient input signals with different sampling rates.• Different triggering options for transient signal capturing (basic triggersand power quality triggers).• Trend Recording: Measurement of RMS current, RMS voltage,frequency, phase, active, apparent and reactive power and power factorover long periods of time (up to 4 million samples possible).Binary/analog inputsAnalog DC Inputs
