Re: Erroneous embedded wattmeter reading
|
The error was related to the cheap attenuator that didn't work correctly. Without attenuator the reading from embedded meter and oscilloscope was inside tolerance with bridge parameter set to 100. Thanks for all.

Take a look in the raw data read from the ATTiny85 over I2C and check if it makes sense (more power / higher readings, for example), if yes, it is just a matter of software calibration.

The reading of the embedded power meter is about twice the reading done with the oscilloscope on a 50 ohm dummy load. The "bridge" parameter in user setting ini file is equal 100. If I reduce the parameter I increase the embedder meter reading but I want to reduce it. The maximum value that the bridge parameter use is 100, if I increase over 100 the reading in the embedded meter doesn't change... Anyone have a problem like mine?
