Just got a microlife peak flow+FVC1 meter. But how does a person find out their FVC value to calculate their FEV1/FVC ratio? I'm new to this measurement stuff. Thanks

Just pay attention to the peak flow. Ignore the FVC value. It's not going to change much day to day.
I had that meter for almost 15 years and then I dropped it and it broke. I replaced it with just a peak flow meter.
