Comparison between features of Fluke 115 and Fluke 117 Digital Multimeters

Fluke 115 and Fluke 117 digital multimeters are part of the same series; Fluke 110. They have many similar features, yet there are some differences among these digital multimeters. Let’s see the main ones in this battle of fluke 115 vs 117.

Similar Features

The common features that these digital multimeters share include a large LCD-display with a LED white light, lightweight, robust body, diode testing ability, measurement of frequency, resistance, AC/DC current, AC/DC voltage, continuity, and millivolts in a range that is same in both models. They are both True RMS devices, and CAT III tested.

Different Features

Now let’s talk about their differences. The primary difference is Fluke 117 has some additional features that Fluke 115 does not have. Fluke 117 has a VoltAlert feature that can detect the presence of voltage without having a connection with a surface.

Another difference is Fluke 117 has an auto-volt feature that is absent in 115. This feature allows the automatic selection of AC/DC volts. Fluke 117 can also prevent false values due to ghost voltage; however, Fluke 115 cannot prevent false readings. So Fluke 117 helps prevent false readings.

Ghost Voltage Detection:

Ghost voltage is the phenomenon of ungrounded leads and probes giving false readings. It occurs because of stray voltages near a surface being measured. As described earlier, fluke 117’s auto-volt feature helps prevent false readings of ghost voltages.

Ghost Voltage can really mess up your readings, so it’s good to have a multimeter that features an auto-volt feature that offers ghost voltage detection.

Low Input Impedance in Fluke 115 and 117:

Another difference between Fluke 115 and 117 is the input impedance. Fluke 115 has a low input impedance which it uses to measure voltage or capacitance, while fluke 117 also offers low input impedance. This feature is especially beneficial if you are going to be using it in high-impedance circuits because it reduces errors due to non contact voltage.

The low input impedance can be a gamechanger as the majority of multimeters today have a high input impedance and this can allow them to show ghost voltage, which is not needed.

Fluke 115 vs Fluke 117 performance

Performance-wise both models are good as they are manufactured by one of the best multimeters producing companies. They give reliable readings and can be used by both beginners and professionals.

Fluke 117 true RMS has more advanced features than Fluke 115, so we can say that it is a better option for electricians who need a multimeter with VoltAlert and auto-volt features for noncontact voltage detection. It is a good general-purpose device that electricians can use for their day-to-day tasks, like measuring voltage.

However, both models of the multimeter cannot measure temperature and also do not offer the data logging feature. So there are no test flame sensors in these fluke multimeters. Such features are usually present in common multimeters, like Klein.Opens in a new tab. The performance of Fluke 115 and 117 could be better if they too have these handy features.
