AD620 instrumentation amplifier with Wheatstone Bridge-based KMZ10B sensor
In your diagram, you have placed your 47k resistor across the outputs of the Wheatstone bridge (+Vo and -Vo). This has loaded up the bridge, resulting in measurement error.

The whole reason we use instrumentation amplifiers like the AD620 is to provide a high input impedance and avoid loading effects.

Remove the 47k resistor from the +/- inputs of the AD620, and place it across the RG pins (pins 1 and 8 as per the datasheet).

Let us know if you're still having trouble afterwards.
