#82203 - Critical information Responding to: ???'s previous message |
You mention the waveform is 250mV peak - what frequency is it? How does this frequency compare with the specification for your multimeter? If your frequency is 20Khz and the multimeter is only good to 1Khz, then that might suggest a problem! As to your cpu being able to read the analog voltage, it depends on your a/d converter. You may need to rectify the output of the flux gate in order to measure it. |
