In-depth Review of the Fluke 1587 Insulation Tester

The Fluke 1587 is optimized for today’s standards, making it easier to test voltage on electrical devices. It includes a live circuit detection feature that enhances user protection by preventing insulation tests exceeding 30 volts. This multimeter can be used for current testing of both AC and DC, making it useful for testing home and commercial equipment.

After 20 minutes of use, the device stops converting battery power. This is a short battery indicator signal that the battery needs to be replaced once. Due to its automatic shut-off feature, electronics can save battery power and prevent wasted energy.

The RMS meter examines linear loads such as incandescent lights and standard motors to produce accurate readings where there is a distorted waveform of voltage or current. For those electronics who want to get a multimeter that helps find the right voltage, the Fluke 1587 is your best bet.


Fluke 1587 vs 1507

When the Fluke 1587 Insulation Tester Multimeter comes on the market you will inevitably ask yourself the question – what is the difference between Fluke 1587 vs. Fluke 1507? The simple answer is that the Fluke 1587 FC Insulation Tester Multimeter is an upgraded version of the Fluke 1507. Here are some additional benefits you can get with Fluke 1587 vs Fluke 1507:

  • The Fluke 1587 Insulation Tester Multimeter comes with a true RMS meter
  • Fluke 1587 brings a low-pass filter to block unwanted voltages when measuring AC voltage and AC frequency
  • 1587 Insulation Tester Multimeter allows capacitance, frequency and diode testing.
  • Fluke 1587 Insulation Tester allows temperature measurements
  • The Fluke 1587 includes an electromagnetic hanging system

All of these features are not included in the Fluke 1507 and are responsible for the price difference between the Fluke 1587 and the Fluke 1507 (more expensive Fluke 1587). If you don’t need any of these features, you should buy the Fluke 1507 instead. If you need more information on 1507, check out our in-depth Fluke 1507 review or read our full guide to the best insulation resistance tester.

Build Quality

If you are looking for a compact multimeter then Fluke 1587 is the right choice. It weighs 1.2 pounds which is light enough to fit in your pocket and mobile enough to move to work. Due to its build quality, it is a good tool for both beginners and professional electricians. The dial switch and button are durable enough to withstand years of abuse. Its power supply takes a 4AA battery. Below it is a fuse bogie which allows users to open the case.

Display and Labels

The Fluke 1587 comes with a backlit LCD screen that is used to read in low light. There is a hold function that freezes the display text, making it easier to lock important measurements.

Function and Performance

Fluke 1587 stands out against the competition when it comes to performance. For example, it can test voltages of 50, 100, 250, 500 and 1000V. This multimeter measures frequency, resistance and capacitance as a versatile tool for electronics. To start the insulation test, press the test button located on the multimeter. It allows you to test diodes for generators, motors and cables. Users can do automatic or manual testing which adds more functionality to the multimeter.


Fluke 1587 has been tested individually for safety and security. For example, it rated CAT III, meaning it can cover items used for closed building applications (such as branch circuits, companies connected to the building’s AC supply, and parts of service panels).


It may be steep but a high-quality product is detailed in the Fluke 1587 review. A multimeter-cum-insulation tester, for which it is running a lot, not least that it is making noise with two pieces of equipment. To save money you can buy a separate multimeter and insulation tester from a smaller company, but it will beat the object.
