    Are we about to get a repeat of the 2021 power crisis in Texas...

    Our heat pump goes into a defrost cycle to prevent buildup when it occasionally gets below freezing here. But the coldest lows I have endured are the mid 20's so I can't speak for performance issues below that. -AK2DM ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "It's the questions that drive us"...

    Hipot versus Isulation Resistance Test

    See pages 10-11 and 16 for HP and IR, slso some good safety/operator guidelines in there. It's been a few decades since I performed such tests. We used Slaughter units (now SCI?), I found it amusing that their tagline was 'Slaughter, The Pro Testers' Requirement of 500VAC for HP seems rather...

    Accelerometer Noise

    Just a thought for a quick test- try removing the chain from the pedal sprocket and repeat the slow pedal movement. Wonder if you are picking up extraneous noise from the sprockets/chain system? -AK2DM ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "It's the questions that drive us"...
