Fluke 867B Graphical Digital Multimeter

The Fluke 867B Graphical Digital Multimeter combines precision measurement with advanced waveform analysis in a single handheld instrument. True RMS voltage and current measurements, resistance to 30 MΩ, and capacitance sensing to 10,000 µF deliver laboratory-grade accuracy across DC, AC, and component-level diagnostics. Its graphical display captures transients as short as 1 µs and renders waveforms up to 1 MHz, revealing noise, distortion, and glitches invisible to standard digital meters. Peak Hold records peaks ≥ 10 µs; TrendGraph™ logging plots high-resolution meter readings over 30 hours at user-selectable intervals from 1 second to 15 minutes. Component test mode checks voltage-current signatures of resistors, capacitors, and semiconductors in-circuit with storable reference signatures. Logic Activity Test indicates transitions to 10 MHz and flags stuck-high or stuck-low conditions. Duty cycle, pulse width, period, frequency to 10 MHz, conductance, continuity, and dB/dBm measurements with 16 selectable impedance references round out a comprehensive troubleshooting platform. The 240×200-pixel LCD matrix supports simultaneous display of meter readings and waveforms in Combo mode, streamlining transient and steady-state analysis in industrial maintenance, electronics repair, and field service environments.
