9:40 : Default reading is not "1", it is an "I" for Infinity. At this point you have the test leads far apart, so you have an "Infinity" of Ohms.
Thanks for that very informative vid.
Just got on those VC60B+ cheap Megga'sfrom amazon but I have nothing professional to test it against.
Looks like I can trust the results - very good - thanks.
Good video. Thanks.
Viewers should know the compressor being tested is a "scroll" type made by Copeland, which, according to Copeland, can show low ohms on the Supco and still be perfectly functional.
You've got your test leads in the wrong way round.
Not that it matters, but *_"E"_* stands for *_Earth_* or *_Ground (black)_* while *_"L"_* stands for *_Line / Live_* or *_Hot (red)_*
Good video though. I have this exact same machine which is why I am watching.

problem is the chinglish manual tells you for IRT to plug in as Jon has done it, seems strange to me too, had mine for a couple years, but never bothered to put it onto a m/metre to see if its right :)
got me thinking now... might test that out
edited: yep ignore the manual and follow the symbols on the device
thank you for connecting this to something real, not just unboxing.
If you're doing testing like this very often, you could put an alligator clip more like a jumper cable clamp on one lead so you wouldn't have to hold it against the pipe.
I've got a variant of this one and it's a nice meter for the price.
I've had the push button version five years and still batteries are good , it tested 1001 volts hooked up to a multimeter. Great for the price
Jon, thanks for taking the time to test that Megohmmeter. I always wondered how those lower priced versions worked. Decent readings, and affordable especially for an HVAC tech that is just starting out (or to have as a backup).
I was also curious about these lower $ ones as well. Was really surprised how well it performed. I think it likely has the same circuit board as the M500. It would make a good backup meter. Thanks Pete
If you want to know how accurate the viccy is us a check box . I have the same tester and I can tell you the accuracy is with in the required tolerance on all settings . Also because you can’t null the test leads on the viccy you need to subtract the resistance of the test leads from the test results. For mine it’s 1ohm They are great little meters . Cheep doesn’t always mean bad . Greetings from a 🇬🇧 electrician
Great video! Comparing the two was a great help. Thx
I purchased one of these as a backup about a year and a half ago, when I checked the voltage and ohms readings against my trusty Fluke I found it to be pretty accurate and the insulation readings weren't much different to my MEGGA
Because of the features and acceptable accuracy it tends to be the one I grab first when fault finding, I use my spare Fluke test leads and the plastic lid actually clips onto the bottom of the meter which saves leaving it laying around.
Considering the type of plastic used for the casing I have found it to be quite robust, it is certainly good value for the money and because of the low cost you don't worry about it getting damaged when working in confined spaces or at height where it may get dropped.
If you just want a cheap handy test meter to throw into your tool bag this one is ideal.
For the price and what I infrequently use it for, (small commercial kitchen refrigeration) yeah it serves well. Gives a quantative value that I can determine if it is "good" or "bad" instead of Supco's idiot lights.
My keysight multimeter has 1000v probes and 6000v certified leads. My fluke just 1000v. I will only ever measure up to 500v with these meters for minimum safety. This unit has 1000v output but the probes only claim 1000v rating and the cable says nothing. This is to say the least dangerous. You really need 100% safety margin at a minimum.
So my advice is get the test leads in the link above and hope they really are 2kv as stated.
This meter puts out less than 2 mA at short circuit. The initial discharge of the internal cap stings a little but the current going through isn't much more than a discomfort after that.
I'd definitely make sure that the device under test is at a state of energy that you're safe to touch with your bare hands before hooking this meter up to it.
If you didn’t have the supco saying it was yellow… what is considered a good reading on a compressor?
I was looking for a tester and came across this on Amazon I was highly suspicious because of the price, but the reviews and this video prove this is a good product if it lasts a year fine or if I drop it; no big deal.
Yeah, It did just fine in my test. It's a very good tool for the $. Thanks for watching!
Can this meter be used to measure ground resistance?
This video really helps a lot :)👍
Great review Jon
Thank you JH
Good video Jon it looks like that meter works
It sure does Mr. Dave. Good spare meter at the very least.
Nice real world test you got there! Bought one, thumbs up :-)
Thanks man!...I try sometimes
I think they need to laugh at their own product! HVAC Technicians........... you are only as good as your tools! good review by the Jon!
I was actually surprised to see how well it performed. I think it likely has the same circuit board as the Supco M500. At the very least it's a good spare meter to have. Thanks Jem
If u were doing a insulation test on a plug circuit at 500v what would be consider as a low reading.. show me in digits what would the tester display would 005. Be low?
Lack of explosion is disappointing
+Justin Hernandez I live to disappoint another day.
It produces an excellent yelp from the apprentice if you press both probes on the back of the (same) hand when locked though. Disappointed most tear downs don't include that test.
I've never heard about having a compressor running before you take meg readings. What's the reason behind that ?
+Meno Meno From Supco instructions: ALWAYS TEST THE MOTOR WINDING INSULATION WHEN THE MOTOR
TEMPERATURE IS ABOVE THE ROOM AMBIENT TEMPERATURE. MOISTURE ON
THE INSULATION WHEN THE MOTOR IS COOL CAN GIVE YOU FALSE LOW LEVEL
READINGS.
Nice review! Should change the title to Supco.... vs...... not very many detailed reviews like this. Thanks again.
They are good
These videos are more like rap sessions for the experienced as opposed to instructional for the learning.
(21:12) - I would pronounce it: *_"Vichy,"_* you know, as in: *_Veni Vidi Vici ?_*

How much it cost
10:45 Where are you reading 1 M Ohm??? Fail to see it....It says Open line....It is measuring NOTHING.
I'd have a leathersmith build me a beautiful case for it with a test lead storage compartment and tell people its "italian made, see, vici"
Furthermore, i'd have to ripout that god aweful speaker. I'd rather sit on a sled with a 2" hole in the bottom and drag my ballsack through an acre of sticker bushes.
What gloves are you using there?
Do you have a link to your clamp DMM?
I apologize for raining on your parade... Only use "Cat" approved tooling (for safety / life reasons)... and stay in range of your factor of safety... that is always number one! This tool does not show as having any cat rating.
Cool way better than the Fluke!😃😊
Not sure about that one :) It's not a bad meter for the $ though. Thanks 4 watching man
+Eric M You should sell your 1587 and you could buy Cuba with change to spare💰.
😉👍
Just can't handle the jump-around presentation of these videos.
Gives me a headache.
