I never heard of the brand TESTEC. It looks like the FLUKE high voltage probe I own. I never felt comfortable using one of these probes. Nice review TP
All these high voltage probes are pretty much the same really. As long as you keep your fingers away from it all, they are good to use. Appreciate you watching.
@@TonyAlbus A comment below talks about them, I have not used their oscilloscope probes before, not too many places seem to stock them, but they are in Farnell who usually stock good quality suppliers.
It is a handy probe to have, was just in the right place and the right time to get it. I think they were selling them off as old stock, judging by the condition of the box. Thanks for watching and comenting.
Great video as always! keep it up im asking if you can review UNI-T UT117C or UT15B/UT17B/UT18B MAX, i heard they are pretty rugged and does awesome job
I don't have any of those meters, so would need to go out and purchase. I know Darren Walker did do a review of the UT117C, that may be of help to you. th-cam.com/video/7mB5jIO4uz4/w-d-xo.htmlsi=ES2CAL_c-raoRnN3 Thanks for watching and commenting.
Yeah, definitely prefer the more reliable brands when it comes to higher voltage testing. VDE screwdrivers will be a while yet, need to build up the holder.
Interesting to know, sometimes materials improve over the year, but basic high voltage design just aims to keep people at a distance. Thanks for watching and commenting.
When would a 100x (4kv rated) standard sized scopeprobe be sufficient to use when looking on voltage on a scope.. tons of smaller things are using high voltage, even smaller component tester that merely are running on a single 4v LIPOcell. Same with a small plasma lamp from China that are running on fx 3x AAA cells and are using a tiny flyback transformer. These smaller HV items that are being powered by batteries, and are in the range of a few thousands volt but with minute current behind.. Would a probe like Testec TT-HV 400 | x100 (4k DC & AC peak) be okay to use on such small high voltage battery powered things. And also looking at mains voltage, not HV products running form mains. I get that getting a high voltage differential probcoe is the preferred way when working with high voltage or even mains, to obtain that isolation, but they do cost decent sum for the casual hobbyists, and not least if a decent 100x HV scope probe could muster some of these usecases. The scope would be floathing, not grounded fx Micsig. Thx for the video, any reason you didn't look at the signal on a scope, as these high-voltage probes with 4mm sockets tends to be quite a bit cheaper then the ones with BNC socket, and wondered how well they would work for use on a scope with an 4mm to BNC adapter, but then again, signal-fidelity is likely not the main narrative on such attenuated resistive probes..
I do not have that particular probe from Testec so cannot comment directly about it, although I might get hold of one later. You can certainly use them for higher voltages as long as the attenuation is good enough to drop the voltage you are measuring down low enough for the rating of the scope inputs. My Micsig has 300V rms rating so with a 100x probe there will be no problem. Battery powered scopes are ideal to maintain the isolation, just be aware that the channels may not be isolated from one another so you can get circulating currents through the channels. Generally with the higher voltages, I will stick to one measurement at a time using just one channel. My Micsig does not have isolated channels, neither does my Picoscope and with those you also have to be aware that the ground will be common back to the USB port of the computer, which can create further problems. I did do a section with the scope but messed up the audio recording, so will have to do that section again and put it in a later video.

TESTEC makes great Probes for oscilloscope.

Nice!! Thanks for the video, got that one myself too, nice price for a great product.

Interesting device agree for something technical probably should spend the money. Now testing be screwdrivers I'm looking forward to that one!
Yeah, definitely prefer the more reliable brands when it comes to higher voltage testing. VDE screwdrivers will be a while yet, need to build up the holder.
That design hasn't changed since at least the 1950s. I have a RCA WG-289 that looks exactly the same.
