(c)

Confirm that the two lines generated on the graph are linear, or close to linear (they will be
linear if their R

values are very close to 1). If not, investigate the cause, correct, and obtain

new test data. Recalibration may be required to obtain accurate values.

(d)

Print the spreadsheet table (load vs. pressure) and attach it to the DHLT in a manner that is
visible to the operator.
