Help with using Apogee MQ-200 PAR meter

Hi,
I just received this unit. It says to choose calibrations, electric and sun. I chose electric. Is this all they mean by calibration?

And so is that it? Just use it?

Thanks,
Ken

Yes. Each setting has a slight offset. What type of lights are you using ?

I am using it for my new LED's. I also want to take a reading on my T5 fixture first to get a baseline for what my tank was used to. Right now the LED's are set low - 30-50-50.

I believe the offset of 10% is only from sun to electric. For all electric, it is 2% between them, unless I read it incorrectly.
