Thank you sir

[@gazyoung8490]

very good, thank you

[@randyboden6087]

Thanks for the 1507 tour! I just started using one. Suggest just taking one reading to ground though. The winding continuity was proven in the first test. If there is a ground, it will be on all of them.

[@tracyzhang7999]

Very useful, and clear! Thank you

[@jimmybarnes2753]

Dont touch them gator clips while that red light is on it will make tears run down your legs !

[@markm0000]

He did at 7:15? Did you break yours doing that?

[@jasonfoster9118]

It'll shock the pee out of you lol

[@davidebiagi9941]

Thanks a lot, I thought mine was fried😂😂😂😂😂😂😂😂

How about a video with the 1507 testing hvac compressor in the real world?

[@luckydiaz5479]

Ser, question for voltage test. How to change from Vdc setting to.Vac? Is it automatically change over while testing on AC voltage?

[@fridayswithbrandon]

The insulation testers only output DC voltage. You can test an AC system but it will be with DC Voltage out of the meter.
If you wanted to put AC voltage to test a system you would need whay they call a high pot tester. Fluke does not make this type of tool.

[@josephstanio4219]

Thanks for the Great video. Curious what would be an unacceptable ohm reading on the 500 volt meg test. Is it a motor specific value? Or is anything under 550 meg ohms not acceptable. Thanks

[@fridayswithbrandon]

It is manufacture specific. But the main rule of thumb is you want them all to be very close. If one is different you probably have a problem

[@chrissanchez6675]

From my factory training, FANUC motor spec is anything above 100Mohms is good. Anything below and you could start to cause damage servo amplifiers

[@TheEspinoza-hf1xf]

What happens if a 3ph compressor fails the insulation test???

[@fridayswithbrandon]

@@TheEspinoza-hf1xf it could indicate it will stop working very soon or it's already no longer able to run. As far as how to repair it would need to be replaced or sent to motor shop for re-winding.

[@mikeadler434]

👍👍

[@ResuelveFilms]

I have a question. If I’m trying to megger a 480v 3phase motor, should I use 500v or 1000v for the insulation test?

[@fridayswithbrandon]

I've heard in the industry most will do twice the operating voltage. Thus 1000v

[@H.A..]

5.5 Mega Ohms??!!! are you sure that wasn't 550 Mega?

[@fridayswithbrandon]

Not sure

[@H.A..]

@@fridayswithbrandon Yeah bro, I think it was 550 Mega, but I could be wrong. Thanks for the post, it's great.
