6. The calculated tooling masses for all (6) points should deviate from each other by less than twice the
worst accuracy rating of the sensor.
•
For example: the Axia80-M20 sensor’s rated accuracy is 2% the range on all axes. For a 500 N F
xy
range and a 900 N F
z
range, the allowable errors of any single data point would be
±
10 N F
x
y and
±
18 N F
z
respectively. Since F
z
has the larger tolerance, then one data point could be + 18 N and another
data point could be–18 N, for a total range (max-min) of 36 N error.
•
In addition, the tooling mass should be within 36 N of the results of this test when it was performed
with a new sensor.
7.
If this test fails, then the sensor should be returned to ATI for diagnosis or recalibration
