HI,
I need to check with you on the programming for a R. M. Young 3-cup anemometer, part number 12102 on a CR800 datalogger. According to the manual, it produces a mV output and has calibration for converting the mV output to meters per second (and other units) of 0.01183 meters per second/mVolt. I would assume that using a single-ended measurement with a 0-5000mV range. According to the calibration sheet, there is a possibility of readings to 5600 mV, would this potentially damage the CR800? I doubt the anemometer would actually spin fast enough to generate that much voltage but it is potentially possible in a hurricane for example.
Thanks,
Larry Treadaway
5600 mV will not hurt the logger. It will even give some measurements a little about 5000 mV (due to calibration safety margins on the A/D system). If you go above 8V (and less than 16V) you will not damage the logger but you may upset other analogue measurements.
Thanks Andrew, much appreciated!
