Should be required equipment. Why isn’t it? Let me explain…
I purchased this almost immediately upon learning of its existence. I’m a strong believer in LDL testing, but let’s be honest: that is almost impossible in real-life industrial field work. Your average plant doesn’t have receptacles located anywhere (much less everywhere) you might need to prove your meter for troubleshooting purposes, much less for confirmation of hazardous energy isolation. Another benefit of a proving unit such as this is being able to practice what you preach: all safety programs stress LDL testing, and this device makes such a life-saving policy remarkably convenient. I’ll go so far as to say that this kind of tool should be a requirement on every electrical job site, and the fact that it isn’t just goes to show that “safety departments” are intended to keep insurance costs down and deflect liability instead of actually improving employees’ work safety environment.

It's a Fluke!
Needed this for a live-dead-live test when teaching the EV world and no 120V is close by. Best meter company hands down and the unit performs flawlessly.

The item was what I ordered and works well.
The item was supplied with batteries installed, so was ready for use as soon as it was received.The Amazon packaging (a simple plastic bag, with no cushening) was inadequate and the items carboard packet was ripped and crushed.

Simple and Effective!
I received the Fluke PRV240 Proving Unit today, so I was extremely eager to try it out. The unit itself is lightweight and fits in the palm of your hand. The fact that it comes with a hanging strap is a very nice touch. The proving unit has a voltage selector which let's you choose between AC and DC voltage. Once you stick your probes into the terminals, a power indicator light turns green to let you know that it is working. I tested the unit using a Fluke 117 and a Fluke 87V to see if the results where going to be the same. After I chose the AC voltage, I was able to get a reading of 240V using both of my multimeters. However, on the DC setting the unit never reached the full 240 DC volts. The highest reading that I was able to get was 238 DC volts using both multimeters. Even though the unit didn't reach the full 240 DC volts, it is still a great way to test a voltmeter before using it on a live circuit. I took pictures of the tests that I took using both of my multimeters.

Nice tool
Just purchased and have practiced with it a bit. So far, so good

Great device to verify your voltmeter is working without exposing yourself to an arc flash hazard.
