You can freely set a wide range of inputs including DC voltage, thermocouple, RTD, and contact signals, by a simple key operation. A lineup of high cost performance models designed exclusively for voltage, thermocouple and contact inputs is also available. In addition, you can select power monitor input options that enable you to measure RMS values of AC voltage and current, active power, apparent power, reactive power, frequency, power factor and phase angle (for both single phase and 3-phase applications).
