The Fluke 87-V is a high-performance True RMS digital multimeter (DMM) designed for professional electricians, engineers, and technicians. It's renowned for its accuracy, durability, and advanced features for troubleshooting complex electrical and electronic systems.






Key Features of the Fluke 87-V


✅ True RMS Accuracy – Measures AC/DC voltage and current with high precision (0.05% DC accuracy).
✅ Wide Measurement Ranges:





  • Voltage: 0.1 mV to 1000V (AC/DC).




  • Current: 0.1 µA to 10A (AC/DC).




  • Resistance: 0.1 Ω to 50 MΩ.




  • Capacitance: 0.1 nF to 10,000 µF.




  • Frequency: 0.1 Hz to 200 kHz.
    ✅ Dual Display – Shows primary and secondary readings simultaneously (e.g., V + Hz).
    ✅ Min/Max/Avg Recording – Captures fluctuations for diagnostics.
    ✅ Low-Pass Filter – Accurately measures VFD (variable frequency drive) outputs.
    ✅ IP Rating: CAT IV 600V / CAT III 1000V – Safe for industrial environments.
    ✅ Bar Graph – 40-segment analog-style display for trending signals.
    ✅ Temperature Measurement (with thermocouple probe).
    ✅ Auto/Manual Ranging – Flexible for quick checks or precise readings.







Typical Applications




  • Industrial Maintenance – Motor drives, control panels, PLC troubleshooting.




  • HVAC – Diagnosing thermocouples, capacitors, and power quality.




  • Automotive – Testing sensors, batteries, and charging systems.




  • Electronics – PCB debugging, component testing.







Comparison to Other Fluke Models




























Model Key Differences vs. 87-V Best For
Fluke 289 Logging & graphing, higher price Long-term data recording
Fluke 117 No True RMS, simpler (CAT III 600V) Basic electricians
Fluke 28 II Extreme durability (IP67, drop-proof) Harsh environments (industrial)





How to Use the Fluke 87-V




  1. Voltage Measurement:





    • Set to V⎓ (DC) or V~ (AC).




    • Connect leads in parallel to the circuit.






  2. Current Measurement:





    • Switch to A⎓/A~, use 10A jack for high current.






  3. Resistance/Continuity:





    • Set to Ω, disconnect power first.






  4. Frequency/Duty Cycle:





    • Press Hz% button while measuring AC voltage.









Safety Tips


⚠ Always verify the meter’s category rating (CAT III/IV) matches your environment.
⚠ Use fused current inputs to protect against overloads.
⚠ Check leads for damage before high-voltage measurements.
