Fluke 115 Review

Who is this product for?

This is a great general-purpose multimeter useful for both home and small industries. It is primarily used by beginner electricians, automotive industry, field engineers, and other home/property maintenance employees.

Just as a side note, this is not the best device for electronics workers as it does not have milli/micro amp measurements.

What’s included

Multimeter; holster; nine-volt battery (installed); 4mm silicone test lead set; and user manual.

Fluke 115 Compact True-RMS Digital Multimeter with Polyester Carrying Case

Overview of features

  • True RMS: This capability built in ensures accurate and precise measurements even when conditions are not perfect by calculating the equivalent DC value of an AC wave. Multimeters without this ability can often have inaccurate and false readings.
  • Auto Power-Off: The Flue 115 comes with a built-in power-off mode which is great for those like me who often forget to turn off the device after use. After 15 minutes of inactivity, the device will automatically go into a shut-off mode. This is not only a great way to save the battery, but also to save money.
  • Display: This device has a large 6000 count LCD backlit screen which is great to see at any angle and even in dark conditions. The display of this unit is one of the best I have seen.
  • Data Hold: The Data Hold function of this model is a great functionality to have. Essentially if you want to ensure the data stays in the device simply press the “Hold” button and the device will store the current measurement until you conduct a new one. Many users enjoy this function as it saves you time of having to write down measurements on paper.
  • Low Battery Notification: Although most users can see the battery indicator on the device, it’s nice to be notified as you often can miss that it’s getting low. When the Fluke 115 gets low on battery it will make an audible noise to let you know which I think is a great function so you’re not stuck on the field with no juice!
  • Auto-Ranging: This device has a built-in system which will ensure the user does not conduct any potentially damaging measurements by automatically selecting the correct range on a given setting. It will also ensure if you select an incorrect mode, an audible warning will be given.

Fluke 115 Buying Guide

Product Tutorial

This product is quite simple to use with one-hand and is easy for new-users to understand the basics.

As a simple beginning overview to get your device setup, the battery requirement is a 9V battery and it is inserted into the back of the device. The two connectors are inserted to the front of the device with the Black one going into the port which says “COM”. The red connector is inserted into the other port.

Here are some of the simple house-hold uses of Fluke 115 which can come in handy for those DIY type homeowners:

  • Battery Voltage Check: To check the pressure of the electricity left in a battery you’ll use the Voltage function which there will be two. One is for testing AC voltage and one for DC Voltage. Since most household batteries are DC (AA, AAA, and 9V) you will use the DC Voltage check which is the second “V” on the device. Simply connect the red connector to the positive end of the battery and the black on the negative end.
  • Power-Strip Testing: For testing a power-strip or extension cord, plug in the cord to the wall. Set your multimeter to the AC Voltage function, which is the one with the squiggly line above the V. When testing AC, there is no positive/negative so it will not matter which end is put into the cord.

As a safety tip to all users, make sure to not let the black/red connectors to touch each other when testing currents and do not let your fingers touch the metal tips ever or you will receive a shock.

There are many other types of tests you can conduct with a multimeter, but these are two simple tests you can do at home. You can check out these two videos which is a great tutorial on how to use the Fluke 115 device:

Alternative Multimeter Devices

A very popular suggestion would be either the Fluke 116 or the Fluke 117 device. Both come at an increased cost, but they have specific benefits useful to certain professions:

  • Fluke 116: This is the perfect device for all HVAC needs as it includes temperature sensor reading. This device is great for anyone dealing with heating and cooling measurements.
  • Fluke 117: The one advantage the 117 has over the 115 is that it has a non-contact voltage sensor which is great for electricians who are unsure if certain devices or surfaces have a current flowing in them and is a great safety benefit for electricians.
