Inside Fluke  - The Measure of Innovation 2015 - Pt 2

Last week I was invited to Fluke in Everett, Washington. They hosted The Measure of Innovation Summit 2015 which was attended by thermography and reliability experts from around the world.

Inside Fluke  - The Measure of Innovation 2015 - Pt 1

Last week I was invited to Fluke in Everett, Washington. They hosted The Measure of Innovation Summit 2015 which was attended by thermography and reliability experts from around the world.

We were given a tour of the Fluke metrology labs, product test labs and product assembly line.

http://www.fluke.com/fluke/dist/home/measure-of-innovations-summit.html?trck=media

In this video I show a demonstration from their product testing lab. What can happen to a multimeter that is not built to the correct safety standards.

http://www.ussafety.com/full_content.php?article_id=1061&full=yes  People around the world rely on product standards to ensure that the products they use will perform the way they are intended. Safety product standards are no different, and millions of employers, workers and health & safety professionals in North America count on standards to help make sure the products they use in the workplace will provide proper, reliable protection for workers exposed to an ever-changing range of workplace hazards.

Who or what are the CSA?:

Keithley 179A Bench Multimeter - Calibrated

This is a follow-up to the look inside video I did on the Keithley 179A. Sean kindly sent me a pair from eBay and I spent some time going through the calibration procedure on one of them.

A Look Inside #9 - Keithley 179A Bench Multimeter -
https://www.youtube.com/watch?v=6Dr0xQMWovE

Post from the previous video (thanks to T Komoski):
"Have a look at this old Radio Electronics magazine, * https://archive.org/details/radio_electronics_1982-04  * page  24. The ad is from Keithley and the price
is $359 @ 1982 MSRP at the time. It looks like they did a comparison against the Fluke model 8050a"

The Fluke 332D DC Voltage standard was a gem during the calibration exercise.

Measuring Inrush Current with an Oscilloscope, Circuit Breakers and Clamp Meters
In this video I use an oscilloscope to measure the inrush current caused by an induction motor starting with a variable speed drive (VFD). I do this to show some of the challenges clamp meters can face getting this measurement as an RMS reading when there is distortion of the waveform.
I also explain how an electrothermal circuit breaker works by preventing overloads and short circuits.

Equipment used:
* Agilent / Keysight DSO-X 2000 Oscilloscope
* HT Instruments HT9022 Power Clamp Meter
* Yokogawa CW10 Power Clamp Meter
* Fluke 43B Power Quality Analyzer
* Thermal magnetic circuit breaker

+Martin Lorton Again, you pinched yourself into the corner little bit. :-)
If you can't measure and calculate overload (inrush) properly, because you have distorted (non sinusoidal) current...just redo video with ordinary induction motor (plugged straight to the grid). Not VFD controlled!
Or try capturing inrush current of...classic light bulb. It will give nice "spike".
Now, as it is, video is probably almost useless and proves nothing (maybe one thing, that you probably don't fully understand meaning and uses of RMS - and "Greg Robinson" comment unfortunately is a bollocks, watch out).
Besides that - "thumbs up" (you have a good YouTube channel).

BTW. Circuit breakers definitely DO NOT "prevent from overloads and short circuits", they can only limit after-effects of overload and/or short circuit when it occurs. This is very common misconception/misspelling.

DIY Bench Power Supply #12 -  Heat Transfer Follow-up

This is a follow-up to the "Heat Transfer between Transistor and Heatsink / Thermal Resistance" video. I demonstrate and use the Extech GX900 multimeter which helped me remotely monitor the status of the tests via Bluetooth.

http://www.extech.com/instruments/product.asp?catid=48&prodid=821

Buy the GX900 here: http://astore.amazon.com/m0711-20/detail/B00OZ8TAJK

I was asked to test a mica TO-3 washer and heatsink compound.  I was also asked to test active cooling with a fan both drawing air away from the power transistor and blowing air directly on it.
