5. Verify the LVDT
a. With the loading frame mounted in the bath at the test temperature, remove all beams from the supports.
b. Place the step gauge disk in any position and apply the provided two 50g weights to the weight pan.
c. Compare the measured displacement to the known gauge disk location. This information can be found on the
Certification of Conformance form, as well as on the main Verification screen.
d. If the known dimensions differ from the measurements by more than ±5µm, standardization is required. Press
the “Standardization Required” button and then press the “Next” button.
e. If the measurements are within ±5µm, press the “Verification Complete” button and then press the “Next”
button to move to the next section.
6. Verify the Load Cell
a. Verify the Contact Load
i. Place the Non-Compliant Beam on the sample supports and apply a 20mN load ±10mN using the zero
load regulator. Add a 2g mass to the weight pan.
ii. Verify the increased measured load is 20mN ±5mN. Add the second 2g weight to the weight pan. Verify
the increased measured load is 20mN ±5mN.
iii. If the measurements do not fall within these ranges, standardization is required. Press the
“Standardization Required” button and press “Next” to move to the next section.
b. Verify the Test Load
i. Place the non-compliant beam on the sample supports.
ii. Apply 20mN ±10mN load using the zero load regulator.
iii. Add two 50g weights to the weight pan.
iv. If the increase in measured load falls within 981mN ±5mN press the “Verification Complete” button and
then press the “Next” button to move to the next section.
v. If the increase in measure does not fall within 981mN ±5mN press the “Standardization Required” button
and then “Next”.
7. Verify the System
a. Ensure the load frame is in the bath.
b. Place Confidence Beam on the sample supports.
c. Apply two 50g weights to the weight pan.
d. Press “Record”.
e. Apply two additional 50g weights to the weight pan and press “Record”.
