The load cell for direct thrust measurement is undergoing the first test.

The graph shows the voltage noise without changing loads.

A 100g calibration mass results in a value of about 35000.

The ADC integer number is 1000x that value, so 100g result in a value of 35.000.000 - but the noise peek-to-peak is about 60000, so it´s not satisfying.

That discrete jumps in the lower picture are annoying. A pure noise whch keeps a certain mean value would be great, but these jumps will make it more difficult distinguising on/off phases.

The actual signal/noise ratio is too low for detecting EMdrive forces, so I´ll try to reduce the noise further.

Currently, a differential amplifier feeds the ADC. I´ll try to connect the load cell directly to the ADC. WIth the high oversampling resolution I can maybe get rid of the preamp and its noise.

For test purposes, the time value divided by 5 gives the seconds of measurement.
