The Fluke 75 Series II is a handheld digital multimeter engineered for electrical troubleshooting and field measurements across professional maintenance, service, and diagnostic applications. It combines a 3200-count digital display with a 31-segment analog bar graph—updating at 2.5 Hz and 25 Hz respectively—to deliver precise numerical readings and real-time trend visualization. The instrument measures DC voltage (320 mV to 1000 V), AC voltage (3.2 V to 750 V, sine wave), DC current (32 mA to 10 A), AC current (32 mA to 10 A), and resistance (320 Ω to 32 MΩ). Additional functions include continuity testing with a 4096 Hz audible beeper and diode testing with 2.8 V measurement voltage and 1% accuracy.
