The Fluke 1587 is optimized for today’s standards, making it easier to check the voltage in electrical devices. It includes a live circuit detection feature that increases user safety by preventing to do insulation tests that exceed over 30 volts. 

This multimeter can be used to test both AC and DC current, making it useful to test home and commercial appliances. 

After 20 minutes of use, the device turns off to converse battery power. It’s low-battery indicator signals once the battery needs to be replaced. Due to its automatic shut off feature, electricians can save battery power and prevent wasted energy.

The RMS meter creates accurate readings when testing linear loads, such as incandescent lights and standard motors, where the voltage or current has a distorted waveform. For electricians that want to get a multimeter that helps with finding the correct voltage, the Fluke 1587 is your best bet.

Fluke 1587 vs 1507

When in the market for a Fluke 1587, you’ll inevitably ask yourself the question – what’s the difference between a Fluke 1587 vs Fluke 1507? The simple answer is that the Fluke 1587 is an upgraded version of the Fluke 1507.

Here are the extra benefits you’re getting with a Fluke 1587 vs a Fluke 1507:

  • The Fluke 1587 comes with a True RMS meter
  • The Fluke 1587 comes with a low-pass filter to block unwanted voltages when measuring AC voltage and AC frequency
  • The Fluke 1587 allows for capacitance, frequency, and diode testing
  • The Fluke 1587 allows for temperature measuring
  • The Fluke 1587 includes an optional magnetic hanging system

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

Build Quality

If you’re looking for a compact multimeter, the Fluke 1587 is the right choice. It weighs 1.2 lb, which is light enough to fit in your pocket and mobile enough to be transferred in the workplace. Because of its build quality, its a good tool for both apprentice and professional electricians.

The dial switch and button are durable enough to withstand years of abuse. Its power supply takes up to 4 AA batteries. Underneath this is the fuse compartment, which allows users to save from open up the case.

Display and Labels

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

Function and Performance

When it comes to performance, the Fluke 1587 stands out against the competition. For instance, it can test voltages ranging from 50, 100, 250, 500, and 1000V. This multimeter also measures frequency, resistance, and capacitance making it a versatile tool for electricians.

To start the insulation test, press the TEST button located on the multimeter. This allows you to perform diode tests for generators, motors, and cables. Users have the ability to conduct automatic or manual testing, which adds more functionality to the multimeter.
