Good Day,
I have an 883 SF AWD dyno... due to the location of the front load cell it typically is calibrated with a negative number, page 19 of the manual states this method is possible....
"Not all load cells are perfectly bi-directional and have exactly same calibration factors
in both compression- and tension- directions. To assure highest possible measurement
precision you should perform a "negative" calibration (use negative "Calibration
weight" value). "
i am unable to enter a negative number...tried - and ()
thanks for the help... version 4.0.41.0

You mean the load to be applied in compression instead tension?
If we assume that the load cell works in both direction (tension and compression) and has linear output, you can switch Signal+ and Signal- wires.
Don't forget to switch them back after calibration.
Another option is to use a "negative calibration", but I'm not sure how exactly it works.
You can calibrate using the normal method (i.e. positive numbers). When you are done, click Reverse calibration.
