Buying Guide: Who Should Buy the Fluke 117 Multimeter?
The Fluke 117 Multimeter is not just another tester—it’s designed for specific users:
Professional Electricians → Perfect for residential and commercial installations.
Maintenance Technicians → Quick troubleshooting in facilities and equipment.
DIY Enthusiasts & Hobbyists → Great for accurate home electrical projects.
Students & Engineers → Reliable tool for lab experiments and learning.
If you need a safe, reliable, and accurate tool for general electrical troubleshooting, the Fluke 117 is an excellent choice. However, if you require microamp measurement for HVAC sensors, the Fluke 116 might be more suitable.
Real-World Usage & Circuit Application Examples
The Fluke 117 Multimeter can be applied in multiple real-world scenarios:
Household Electrical Testing → Measure AC mains voltage with LoZ to eliminate ghost readings.
Panel Board Diagnostics → Safely check circuits with the non-contact voltage detector.
Electronic Circuit Testing → Measure resistance, continuity, and capacitance accurately.
Power Outlet Checks → Verify line frequency and voltage stability.
Battery Testing → Check DC voltage on automotive or UPS batteries.
Example Circuit Application:
Suppose you are troubleshooting a 230V AC motor connection in a factory panel. With the Fluke 117, you can:
Use non-contact voltage (NCV) to confirm live wires.
Switch to LoZ mode to eliminate ghost voltage from capacitive coupling.
Accurately measure current up to 10A for motor load checks.
Comparison with Similar Fluke Models
If you want NCV detection + LoZ feature, the Fluke 117 is superior to the 115 and 116. If you need high precision lab-grade accuracy, the Fluke 177 is better.
Step-by-Step User Guide: Using the Fluke 117 Multimeter
Power On → Insert the 9V battery and turn the rotary dial to the desired mode.
Check Voltage →
For AC mains, turn to “V~” and connect probes.
For DC circuits, turn to “V⎓”.
Use LoZ Mode → Select low-impedance to eliminate ghost voltages.
Test Continuity → Turn dial to diode/continuity and listen for the buzzer.
Measure Resistance → Switch to Ω mode and connect probes across the component.
Measure Current → Move the red probe to the 10A jack and select current mode.
Capacitance Measurement → Switch to capacitance mode and connect across capacitor.
Frequency Check → Use Hz function for AC line frequency.
NCV Detection → Simply hold the meter close to wires—no probe required.
FAQs About Fluke 117 Multimeter
