Sure is an expensive one, the cost of the apparatus I work on and the functionality of the tester justifies it for me though, but it is niche work. The UT512 will be great for the majority of work. Does lack a 100V test voltage for bearings for my work. Thanks for watching.

Thanks for your comments.👍

The Fluke 1587 can certainly be used for general fault finding, but I find it has limitations for trending insulation and winding resistance which is what I use for establishing the condition of a motor. There are a number of options for assessing motors, and it depends on the type of motor. The more data you can trend over a period of time, gives a more informed health assessment. For a low voltage motor, online, you can use a power meter to assess the operating status, vibration monitoring, thermography and current signature analysis if you have an FFT scope or a specific analyser. For offline low voltage you can measure winding resistance, insulation resistance, capacitance, inductance, impedance. You can also plot the impedance as part of a rotor influence check, although that can be awkward on an installed motor. There is also a baker surge test for interturn faults. It is then just basic cleaning, checking mountings, connections, and cooling fan etc. For higher voltage motors, you can add partial discharge for online monitoring, this can also be done offline if you have a voltage source. For offline tests you can add in the Dielectric Absorption Ratio, Polarisation Index and Dielectric Discharge Tests. How much you can do depends on the kind of access you have around the motor and control panel. How much you want to do is a risk / cost assessment with reference to historical maintenance / failure data. There is no right or wrong answer really.

@three-phase562 Thank you, our reliability engineers have taken over the vibration and thermal monitoring. Unfortunately, the company will not spend the money for better insulation testing, telling us "you have a tool allowance". Yet a good megger unit is 2x-3x of our allowance. I am IR certified, but my department heads see no need to continue with more testing training. Thank you again for responding to my questions

@@shadowulf It depends on what your relative costs are. I used to substantiate training and test equipment for company electricians against the costs and effectiveness of contract works. It is usually quicker for site personnel to deal with failures, than bringing in contractors, so it is better to have them doing the maintenance out on site and getting familiar with the equipment. Does depend what business you are in though and how the plants operate.

@@three-phase562 That has been my argument for my superiors for a long time. Even having someone trained and on staff while a contractor is doing the testing, to me, is an assurance that the work is being done. Unfortunately, my supervisors change often. So getting anything going usually meets with varying levels of resistance.

No, not at the moment. I will at some point purchase one for a comparison to these. Thanks for watching.

Thanks for watching, VDE socket set is a bit of a niche tool.

A lot of these rebrands appearing on the market now, with the majority coming from Taiwan. Price range for what is effectively the same thing is wild though.

No, there is no beep in diode mode.

Takes 3 AAA batteries with around 100 hours operation based on sums. I don't use the meter extensively, so I get around 18 months usage from one set of batteries.

Glad you found the video useful. Hopefully, the screwdriver works out for you okay. Thanks for watching and commenting.

Nah, just a little short video to help someone out. inrush pulse is set to 100 ms width.

@@three-phase562 Thanks.

I have seen the PB Swiss digital screwdriver, Wiha also have a digital version. Wiha is twice the price of the PB Swiss over here though. I like that you can use the standard 1/4 hex drive bits with them, makes them much more flexible to use. I generally collect the items I want to test over a period of time, as money allows. I think the Tools Tested channel reviewed a variety of non-vde torque screwdrivers, which may be worth a look.

Thanks for watching and commenting 🙏🙏

Not sure about the HT208F as mine is the HT208D, but with that you can measure inrush and have a min/max option. Both will record the value and save it to screen for you to read, but there is no memory function to recall at a later date. As long as you don't change the function or restart the reading, you should be able to measure a start-up current for a car etc.

If u are in the car start it u need a person to hit the hold while its displaying? It should hold till u walk back out to front of vehicle?

@@HYDROMAXplus If you set the meter to measure inrush using the function button and clamp it around the wire then it will measure and hold the initial current surge for you to read when you go back to the meter. If you use the max function, then it will measure and hold each successive increase in current. You may have to set the meter to the manual range before starting the max function, as it cannot auto adjust the range in the max function.

@@three-phase562 but they told me Inrush is only AC

Not heard of KS-Tools before, thanks for letting me know about them, I will check them out. Appreciate you watching and commenting.

Depends exactly what you want from the multimeter. The UT196, won't be as accurate or rugged as the Fluke 87V. If you are in need of calibration, then there will be no problems with the Fluke, you could get the UT196 checked, but you may not be able to have it adjusted and technical support from Uni-T will likely be minimal. On the other hand if you want to measure above 1000V, then the UT196 will be more user friendly than the 87V and more cost effective, if you are looking to buy new.

I will have to set the test up again over the next couple of days and get back to you. I will need to verify how accurate my set up is for injecting low currents, say 1 to 5A in 1A steps.

@@three-phase562 Thanks a lot! I guess the difficult part is to generate a surge load. I've been thinking a way to generate it in the past, but in the end I always end up testing on a small fridge, which is a moderate surge load.

I have run some more tests at the weekend. \basic results for AC at 50Hz; 1A injected UT216C reads 0.4A 2A injected UT216C reads 1.4A 3A injected UT216C reads 2.4A 4A injected UT216C reads 3.0A 5A injected UT216C reads 3.8A I made a short video showing the results if you want to see the readings for yourself; ua-cam.com/video/yBLhVWDrE8s/v-deo.html Hope this helps.

@@three-phase562 People like you make UA-cam a great place. I'm going to the new video to comment there.

There is a bit of the old Cropico stuff around. Just picked up the resistance bridge version of this, but it has been left sat around and the batteries leaked inside. Shame they aren't looked after better. Most of mine I get off eBay as I am never in the right place when someone is throwing out the old stuff 😃😃.

Would could possibly go wrong 🤔🤔

That's not good to hear, Crescent do have a lifetime warranty, may be worth seeing if you can get it replaced.

Glad you enjoyed the video. Appreciate your support throughout the year and all the best to you for 2025.

Appreciate you watching and commenting, all the best to you for 2025.

Thanks for watching.

Thin spanners are handy at times, and the set from Duratech seems reasonable. I know what you mean, but I think I am going to have to pay Amazon Japan a visit in the New Year 🤣🤣.

A slim set of spanners are a handy thing to have on occasion and these seem decent enough for the money. Appreciate the comment.

Thanks for watching, those two ratchet spanners seemed to be a decent option.

Glad you enjoyed the video, thanks for watching and your support throughout the year. You and yours have an excellent Christmas too.

Thanks for watching and commenting. 🙏🙏

I have noticed a few of the instrument now coming out with increased resolution, but then with an accuracy spec into double digits, which like you say makes the last digit relatively pointless. Thanks for watching and commenting.

I only tend to use the NCVs for generally sniffing around cables anyway and never rely on them that much, so the sensitivity isn't a big deal for me. My Wiha unit seems to eat through the batteries, so it doesn't get used a lot especially as the battery cover is a bit of a pain to remove. I find the jobs are starting to become more complex needing a bigger variety of tools so space saving in bags is important, otherwise I have to develop another loadout with a new bag.

Yes, the 1587 is quite a slender instrument and is suited quite well to the SB-LD. I don't have the 376, so could not guarantee that it will go alongside but the clamp meters that I have fitted reasonably well next to the 1587. Thanks for watching.

​​@@three-phase562Would the 1587 and a Fluke 89 fit inside? If so, this will eliminate another bag from daily loadout. Thanks Nevermind, I see you got an 83 to fit with it. Very encouraging

@@shadowulf Yes you can get both of those meters in the pouches. Bit more of a struggle with the leads, but they do go in. I have put a picture in a community post for you to see. ua-cam.com/users/postUgkxXTD6q9L7q_ZowzhqBCcC83OJmgpMEjww?si=TbFyl-okPRU6dob_

Man of your caliber, you could always build yourself one from an old microwave transformer!

@@three-phase562 i have a rule i never mess with microwave transformers

Unfortunately, when you start looking at the higher test voltages, the price does start to go upwards ☹☹. Thanks for watching!

Good to know you are a Beta tool user. Thanks for watching and commenting.

They are a little bit touchy to use, the Kaiweets is a bit more stable than the Bside. Some of it was down to the PRV240FS cutting out as well. I should probably set up a better experiment with them really. Thanks for watching and commenting.

Yes, the sensitivity would likely be a measurement of the electric field strength in V/m. I have never seen any NCV pen with a sensitivity specification though in their operating sheets. I can't even find a specification for the voltage sense function for my Keysight U1282A. It just seems to be an add on function for general use with no defined parameters. You could set up a little test and measure the activation distance from a constant source instead of the haphazard approach I adopted in the video. Thanks for watching and commenting.

Always a bit of a concern with these cheap NCV pens. Thanks for watching TETC.

Yes, I do have a little chuckle when I have tight accuracy requirements with the transmitters and then you look at the actual sensor itself. In theory, the sensor should be linear though so you can calibrate out its discrepancy. Thanks for watching.

@@three-phase562 Perhaps that might be an interesting topic for a future video. The "global error" that is never referred to by manufacturers of sensor & transmitter systems is almost a science in itself! Applying uncertainty of measurement to measured data, and then trying to explain to non-technical customers was something I always found challenging!

@@scottshaw1310 Added to the list, I will see if I can put something together. I have purchased a little HMI/PLC to play with so may be able to utilise that although I have to learn to program it first. Thanks for the idea.

It should be good with having the independent VDE certification, but it is a highly cloned set of drivers. Will be interesting to see how the last in the long run, only one way to find that out though.

There are just so many of these types of sets around now, it is easy to get caught out.

Sorry to hear that, I haven't had any issues with mine. Spec sheet says they are good for 245 Nm, so I wouldn't expect any problems. Thanks for sharing, so others are aware.

Calipers are doing fine, but I have only had them for a couple of months, so no long term perception from me.

Glad you found it useful, thanks for watching and commenting.

Yeah, I think it was mentioned before. If you search for three-phase562, that is the handle UA-cam have given me and it will find the channel. Thanks for watching and commenting.

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. ua-cam.com/video/7mB5jIO4uz4/v-deo.htmlsi=ES2CAL_c-raoRnN3 Thanks for watching and commenting.

Using the interna compensation would be the usual way to do it, I just wanted to show what they compensation was effectively doing. If you have the luxury of using specific thermocouple types then you can use the compatible terminal blocks, but they are mighty expensive. Unfortunately, these little meters can measure multiple types of thermocouples, so they just have standard jacks and rely upon the cold junction compensation.

@@three-phase562 Yeah, was interesting to see you do the cold junction and try to bring it to 0C.

They are available on the Amazon and eBay sites. If they aren't available on your local Amazon, you can create an account on Amazon Japan and order from there.

Where is manual pdf
