I think it is just Fluke's PR department trying to big themselves up again. The phrase MegOhmmeter was used to describe an instrument capable of measuring MegOhms, I believe the original test voltage was 250V DC and then raised to 500V with the Series 2 Megger. As far as I am aware, both the terms MegOhmmeter and Insulation Tester were created by Evershed and Vignoles, the former being shortened to 'Megger' in 1903 that they then registered as their trademark. Even back in the 1920s, the sales literature and instructions on the Series 2 Megger utilised the phrase Insulation Tester. It wasn't until 1987 after Evershed and Vignoles were taken over by the AVO group, that they used Megger as their company name. The introduction of DAR and PI test ratios is more about analysis of insulation systems rather than the actual test instrument. Generally speaking, DAR and PI are more predominantly for use at higher test voltages above 1000V. Whilst you have the basic insulation testers up to 15kV test voltage now, alongside these you have the Dielectric Diagnostic Analysers that incorporate more test functionality such as DD ratio, Tan/delta and frequency response analysis alongside more traditional DAR and PI ratio tests. You then step up to HiPot tester with outputs 100 kV+. Generally seeking you can argue that they contain a MegOhmmeter or even a GigOhmmeter now as they all measure high resistance values. The 1587FC and instruments like this are a combination of an insulation tester and multimeter and often go by the name of Insulation Multimeter. The first one I saw was the Keysight U1461A circa 2014 to 2015.
TP it took me a while to respond to your commentary, I wanted to make sure I read everything that you wrote. And as always you’re on point I really appreciate the thought that goes into videos or commentary. Thanks sir keep it coming.
I love your channel... I’m in the industrial/agricultural industries and your info has helped me make some purchasing decisions. Do you have a patreon?
No sir at the moment I do not. A lot of my viewers keep asking me to set up a patreon account. When I do I’ll mention it in the closing of my future videos. Thank you Tim for watching my and I’m glad I was able to help you in some form or fation , also thank you for the thought of wanting to contribute. Sincerely I thank you 🙏 Tim.
I’ve actually been trying to double down on this subject in hopes my employer will see the value. The Megger mit430(?) is what I e been looking at. Having the ability to DAR and PI , store, Bluetooth etc....seems great. But hey when you’re spending other people’s money , you look at things a lil different. Thanks for this....Doug
JT have you ever heard of a company called RISHABH ? I just did a review of their insulation tester about a week ago from what I read they’re a big deal in India ?
I apologize for any inconvenience I record with my IPhone 📱 next time I’ll get closer to the mic 🎤. But I’m glad you enjoyed the video I won’t ask you to subscribe to my channel until you take a look at a few more of my videos. Then if you like what you see please subscribe we’ll love to have you to keep seeing what everyone else is seeing. You won’t regret it I GUARANTEE IT !!!
@@TheElectriciansToolChannel That is true...They are a true value brand ..As a comparison i still have my KAISE SK7711 Clamp meter that i got when i was employed at the electrics department at my first job back in 1988 ☺
What insulation tester wouldmyou recumend with bang for the buk in mind
Out of the testers displayed in this video , if I had to pick one that gives more punch than the price it would be the. KLEIN ET600 Insulation Tester.
Another good video sir! Nice work !
Thanks Mr Leamerz👍🏿👍🏿

Can you do a comparison insulation test with all the meters and compare it to the fluke .
I’ve done a review on that subject already go to my main TH-cam channel page and scroll through you’ll locate it. Thanks for watching 👍🏽

You’re very welcome Doug. Thanks for watching.👍🏿
Just the fact that fluke wrote that B.S. to confuse people makes me HATE fluke as a compainy even more.
You’re absolutely correct it’s a lot of B.S.
JT have you ever heard of a company called RISHABH ? I just did a review of their insulation tester about a week ago from what I read they’re a big deal in India ?
Just go for what sells most and has most reviews.
I kinda agree with you, but not 💯 % .
loved it.... audio needs help

Fluke instruments are good..But the prices on them is ridiculous..Its like Apple products....
I totally agree, but you get what you pay for with FLUKE compared to other meters on the market. That's just my opinion. Thanks for posting.
