Is there a calibration procedure for the mass flow sensor? The manual says to calibrate mass flow sensor for each crop, but it doesn't say in the manual how to do it.

You have to weigh product. You have to go into your menu and start a calibration, combine whatever you want to calibrate for, then once you have enough product weigh it and enter it.

Works really good if you have a graincart with a scale. Otherwise basically you need to weigh one hopper at your closest scale. Once calibrated they are really accurate.

here is the instuctions from the manual

OMHXE13769: 9670 STS and 9770 STS Combines 9670 STS 735201 9770 STS 735301 , Block File: OUO6075_00002B9_19_06MAR09.htm

I calibrated mine last year with a whole truckload and weighed at the nearest elevator. After harvest I wrote down the final bu the combine displayed, then during the winter I hauled it all in. On 30,000bu of product it was out less than 100bu. Not sure what I would do without it.
