cmichael Posted December 2, 2015 Report Share Posted December 2, 2015 I'm having an issue with the AMM-1 (firmware v3.8 ) regarding power measurements. Using Live/Realtime Pwr (or Dyno, etc) when measured power exceeds around 130W, it suddenly reports zero. For example, if I give it a 1KHz sinwave at ~25VRMS, ~5A into 5 Ohms. However, the User's Manual says it can measure up to 15KW. My waveform does start to clip at 75W on the DSO and at 130W it's fairly clipped (clipping is OK in my situation). However, the AMM-1 doesn't report clipping. I'm confident my amp can put out >130W but how can I get the AMM-1 to measure it? Quote Link to comment Share on other sites More sharing options...
