Similarities Between Fluke 115 vs 117


Let’s talk about similarities that both Fluke 115 and 117 share!

  1. TrueRMS digital multimeters: Both Fluke 115 vs 117 are true RMS multimeters which means they have the capability to perfectly analyze the fluctuating signals. Especially those signals, that might be difficult to record using an ordinary non-RMS multimeter.
  1. Handheld style multimeters: Both units have elegant look and with their compact size, one can easily hold them in one hand. So, one can get the job done single-handedly.
  1. High-resolution LCD: Both units have high-resolution LCD on which the thick digital display is pretty easy to read. Moreover, by turning on the backlights, one can brighten up this display to allow old technicians perform their job on-time.
  1. Warranty: Fluke offers 3 years of warranty on both of its units. So, no unit has an upper hand over the other in this department.
  1. Auto/Manual Ranging multimeter: Both units can perform the operation on auto and manual ranging mode. That makes them equally suitable for newbies and professional electricians. On the lower bottom, there is a bar graph that shows signal’s variation in real-time. Thus, it giving an analog feel to technicians who have worked with analog multimeters.
  1. Safety Ratings: Both Fluke 117 and 115 are CAT III (600V) safety rated multimeter units. That acts as a guarantee that they are safe and risk free to use. Thus, they’ll handle the transient voltages by keeping you safe.
  1. Certifications: Both units have got IP42 rating thus they are dustproof and having safety approval from CSA and UL further enhances their credibility.
  1. Battery: Both products under comparison operates on a 9V battery which is easy to find and replaceable. Moreover, you won’t find a need for their calibration. But doing it once a year would give you peace of mind.

Fluke 115 vs 117: How they differ from each other?


Fluke 117 is an advanced multimeter especially design for electricians to help them during troubleshooting in hospitals, schools and commercial buildings. On other hand, Fluke 115 is designed for general-purpose testing and is less advanced multimeter unit than the other.

Fluke 117 having the non-contact voltage detection functionality is pretty effective in voltage checking especially of high voltage wires which Fluke 115 fails to do. Similarly, there is an LoZ ghost voltage filtration feature in 117 that 115 lacks.

LoZ feature helps in filtering out the stray voltages that ultimately helps in getting more accurate results. So, one can say, measurements might be more accurate with 117 than of 115!


Individual Products Reviews

In this section of the article, we’ll review both Fluke 115 and Fluke 117 individually and more in-depth. It’ll further simplify the multimeter selection process.


Fluke 115 Review


We’ll explain Fluke 115 from four different perspectives including the design, functions, safety and use. Let’s discuss each element separately.

Measurements:

Fluke 115 is capable of measuring AC/DC voltage, AC/DC current, resistance, frequency, and capacitance. Its continuity verification functionality and diode testing capability often comes very handy in lab troubleshooting. But you would be limited in checking transistor with Fluke 115.

Design:

There are no built-in kickstand or a magnetic hanger in Fluke 115. So, handling the unit would be difficult especially if you are just getting started. But, you’ll get a nicely designed carrying case that would help you in keeping not only multimeter but the testing leads, extra batteries etc, at one place.

The digital display of nearly all Fluke meters is highly appraisable. Same is the case with Fluke 116. On its widescreen, the thick digital display is easy to read with 6000 display counts. Moreover, the old fashioned technicians would love the bar graph located at bottom of the screen. It helps in seeing the fluctuations in real-time.

You’ll also like its amazing interface which is easy to understand for beginners as well as professional technicians.

Functions:

Fluke 115 is an auto-ranging multimeter that makes it a beginner-friendly multimeter unit. So, you won’t have to manually adjust the range for every reading.

Most of the fluke multimeters are true RMS multimeters. It means they can analyze the signal’s variation without relying on its waveform or fluctuations. So, you can comfortably play with the nonlinear signals.

Additionally, by operating the unit with min/max mode turned on, would help the user in the filtration of highs and lows of the measured signals. Thus better fluctuation estimation leads to the right fault diagnosis and its troubleshooting.

Two important features, namely auto-shutoff and data hold, are present in Fluke 115. They’ll help the battery to last longer and holding reading to note it later respectively.

Safety:

The dual fuses on its input circuit and strong rubber holster with tough outer casing help in protecting the unit from overloading or jobsite scratch and abuse. Thus, expect the unit to last long!

Fluke is a CAT III rated multimeter unit that ensures its safe nature. But avoid using it in areas with high power especially in the troubleshooting of the commercial buildings.

However, bear in mind that Fluke 115 lacks a non-contact voltage detector and live line testing functionality. Thus, you can’t confirm the voltage flow in high voltage wires easily with this unit.


It’s long-lasting nature of Fluke 115 due to which it is highly loved by the trainees and home DIYers. It may not be well suited for high-end industrial testing. However, it would be a great product for lab testing and home troubleshooting.


Fluke 117 Review


Measurements:

Just like Fluke 117, Fluke 115 can also measurevoltage, current, resistance, frequency, and capacitance. If you are a lab geek who like performing experiments then verifying circuit continuity and testing diodes won’t take more than 5 minutes of yours.

Still, bear in mind that you won’t be able to test transistor with this unit.

Design:

Unlike Fluke 115, there is a humble stand on its back that’ll support the multimeter during lab testing. Simply prop it out and it’ll keep the unit sturdy.

However, absence of magnetic hanger snatches the flexibility of hanging the multimeter unit and doing the task singlehandedly. Moreover, in order to get carrying case, prepare to spend extra bucks as it’s not included in the package!

Just like Fluke 115, high resolution, 6000 counts, the thick digital display is another appraisable thing that Fluke 117 offers. So, you’ll find no difficulty in reading out the display.

Functions:

Just like Fluke 115, Fluke 117 is also an auto-ranging mulitmeter and has true RMS functionality. Thus, it’s pretty easy to use multimeter and one can analyze non-linear signals easily.

Min/max functionality also comes very handy in analyzing the disturbing signals. One area where it has an edge over Fluke 115 is its LoZ functionality. It filters out the stray or residual voltages to help achieve better accuracy.

Lastly, just like any other multimeter of Fluke, auto-shutoff and auto hold functionalities are present in Fluke 117 as well.

Safety:

Fluke 117 provides nearly the same safety as provided by the Fluke 118, including the dual fused overload protection, rubber holster and strong outer casing for drop-protection. It is also a CAT III safety rated device that further increase the reliability.

However, two distinguishing features that make Fluke 117 more trustable in comparison with Fluke 115 include non-contact voltage detector and live line testing functionality. So, confirming the voltage presence is very easy with Fluke 117.


Being a high end multimeter unit, one can use Fluke 117 for commercial and residential troubleshooting especially in areas involving high power. Moreover, it would also be the right product for industrial use as well. But never expect to perform very high-end troubleshooting with this unit.


FAQs:

Does Fluke 117 measure temperature?

No, Fluke 117 multimeter doesn’t offer temperature measurement. So, if your testing often involves temperature measurement, go for some other multimeter unit. 

Does Fluke 115 measures milliamps?

No, Fluke 115 doesn’t offer milliamps measurement. So, it might not be a good option to go for electricians and lab technicians.

Do Fluke multimeters need calibration?

Fluke multimeters are high end so you won’t have to get them calibrated quite often. However, calibrating multimeters once a year would give you peace of mind.


Final Thoughts:

In nutshell, Fluke 115 is the right buy for general-purpose tasks, not involving high voltages or commercial use. If you would be working in a more demanding environment that may require features like non-contact voltage detection, then going with Fluke 117 would be a sensible choice. But only then, if you can afford to buy!
