In this post we compare two popular Multimeters – Fluke 114 and Fluke 115. Although their product names are separated by a numerical value of only 1, the differences are significant.
🏷️ Fluke Multimeter Deals ⭐⭐⭐⭐⭐
In this post we compare the spec differences and make a recommendation on which one is more relevant for you. Bottom line: It really depends on how you plan to use the instrument.
Quick Summary
The Fluke 114 and Fluke 115 are both True RMS multimeters designed for professional and home use, but they differ in functionality.
The Fluke 114 is better suited for electrical troubleshooting, featuring a Low Impedance (LoZ) mode to eliminate ghost voltages, but it lacks current and capacitance measurement.
The Fluke 115, on the other hand, is a more versatile general-purpose meter, capable of measuring AC/DC current (up to 10A) and capacitance (up to 10,000 μF), making it ideal for electronics, automotive, and HVAC applications.
If you need a basic but reliable electrician’s tool, go for the Fluke 114, but if you need broader functionality, the Fluke 115 is the better choice.

What is Auto-V LoZ in Fluke Multimeters?
Auto-V LoZ is a function found in some Fluke multimeters.
“Auto-V” refers to automatic voltage detection, which allows the multimeter to automatically determine whether the voltage is AC or DC and select the appropriate mode for measurement.
“LoZ” stands for low impedance, which helps to prevent false readings caused by ghost voltages. Ghost voltages are stray voltages that can appear in capacitive or inductive wiring even when there is no actual hard voltage present. This feature is particularly useful in environments with complex wiring systems where ghost voltages might lead to inaccurate measurements.
Key Differences
Low Impedance (LoZ) Mode
- The Fluke 114 includes LoZ (Low Impedance) mode, which helps eliminate ghost voltages in electrical circuits, making it great for troubleshooting.
- The Fluke 115 does not have LoZ mode, meaning it may not be as effective for detecting real voltage in noisy electrical environments.

Current Measurement
- The Fluke 115 is capable of measuring both AC and DC current up to 10A, making it useful for automotive, electronics, and HVAC applications.
- The Fluke 114 does not support current measurement, making it more suitable for voltage troubleshooting rather than diagnosing power draw.
Capacitance Measurement
- The Fluke 115 can measure capacitance up to 10,000 μF, which is helpful for checking capacitors in motors, appliances, and electronic circuits.
- The Fluke 114 does not include capacitance measurement, making it less suitable for electronics work.
Electrical Troubleshooting
- The Fluke 114 is marketed as an electrician’s troubleshooting meter, focusing on voltage, resistance, and continuity testing.
- The Fluke 115 is more of a general-purpose multimeter with current and capacitance measurement, making it more versatile.
