In this video we take a look at my new Peak Electronic Design Atlas LCR45 LCR Meter.

If you’re interested I have other equipment from Peak Electronic Design.

Over on the EEVblog forum I ask What’s special about the frequency 14.9254 kHz? The answer seems to be that this is 1/67th of 1 MHz, which is probably as precise as the microcontroller they’re using can go.

You can learn more about my ALKOY Capacitor Discharge Pen.

There are accessories available for the LCR45. Stuff I am planning to get includes:

I would get the LX30 – Extension Cable for LCR40/45 but it doesn’t appear to be in stock.

There are cases available but I am not planning to get any of those:
