The FLUKE-123B/NA/S is a compact hand-held industrial ScopeMeter combining oscilloscope and multimeter functions for field troubleshooting and electrical analysis. It features a 20 MHz bandwidth with dual inputs for simultaneous voltage and current measurements, supporting waveform capture, harmonics analysis up to the 51st harmonic, and automated IntellaSet technology that intelligently displays appropriate numerical readings based on the measured signal. The instrument provides comprehensive measurement capabilities including AC/DC voltage (500 mV to 750 V), true-RMS current, resistance, capacitance, continuity, diode testing, and frequency measurements, with a maximum input rating of 600 Vrms CAT IV. Designed for industrial maintenance and troubleshooting, it enables rapid diagnosis of power quality issues, equipment faults, and signal integrity problems in manufacturing and field service environments.
