Ok. So rather than recreate the article describing this, I'm just putting a link to the original RCgroups article.......

It is a super simple (just 2 components again!) Low Pass Filter gizmo which you insert in the flight pack Voltage sensing wires between the battery and the Telemetry sensor input. It hugely improves the accuracy, reliability and consistency of flight pack low Voltage Telemetry alerts. It does this by filtering out all the undesirable spikes and transients which motors and ESCs always inevitably generate. The result of this is that your low voltage threshold Telemetry alarm just works so very much better. The improvement is dramatic. I have included this on almost all of my models now with superb results and far less premature or erroneous low battery callouts.

Disambiguation..... if you Google 'Peter Meter' you may find a device with an entirely different measuring purpose
I didn't name this device, the name was coined by another RCgroups reader. The name just stuck since.

This is a tidied up copy of a post I submitted on the forums a couple months back. The device appears to be quite popular with several being constructed successfully by other RCgroups members. The device is useful for go/no go Tx testing. Especially when the Tx uses twin diversity antennas to ensure they are both operating ok.

Everyone ought to carry one of these in the flight box. I've used mine on the field a few times to verify folks suspect radios. It enabled a definite diagnosis of a club buddy's randomly intermittent low output DX7 G2 (non diversity). It got returned to HH Germany and (eventually) replaced FOC recently. I built the prototype detector a year or two ago.

The device is not calibrated and you can't specifically measure anything with it. However, once used on a few known good 2.4GHz Tx sets, you soon learn what's a healthy normal RF output and what isn't. It just gives a very useful indication of the close field RF signal being radiated from any 2.4 GHz radio Tx. You can also see output from DECT cordless phones, WiFi routers and other WiFi devices with it. Not to mention leaky...Continue Reading
