Record load sensor for
comparison and stability
Check individual load sensors output by
using the Smart Diagnostics and
SD summing card
A load sensor output can be considered stable if
the readings only vary +- 0.01mV. Applying
weight and releasing the weight should show a
very rapid Millivolt change. A slow Millivolt
change can indicate a damaged strain guage.
Inspect the summing junction box for
contamination or damage, and replace if necessary
