j. Press “Finish” to record the calibration constant.
NOTE: The calibration constant should be ≤2.5mN and repeatable within 10% from one
standardization to another. If it is not, contact Applied Test Systems at +1-724-283-1212.
3. Standardizing Deflection (LVDT)
a. Press the “Deflection” button on the Standardization Screen.
b. With the load frame in the bath, remove any beams from the supports and any weights from the BBR3.
c. Adjust the zero regulator to raise the load nose to its highest position.
d. Remove the step disk from the gauge kit and place it on the load frame.
e. Gently rotate the step disk so the locater pin is above the 0 step.
f. Using the zero regulator, gently lower the load nose until the pin rests lightly on the 0 step.
g. Place a 100g weight on the weight pan, wait five seconds and press “Next”.
h. Manually raise the load nose by lifting the weight pan and gently rotate the step disk to the “A” position. Gently
lower the load nose until the pin rests lightly on the “A” step. Wait five seconds and press “Next”.
i. Manually raise the load nose again and gently rotate the step disk to the “B” position. Gently lower the load
nose until the pin rests lightly on the “B” step. Wait five seconds and press “Next”.
j. Manually raise the load nose again and gently rotate the step disk to the “C” position. Gently lower the load
nose until the pin rests lightly on the “C” step. Wait five seconds and press “Next”.
k. Manually raise the load nose again and gently rotate the step disk to the “D” position. Gently lower the load
nose until the pin rests lightly on the “D” step. Wait five seconds and press “Next”.
l. Press “Finish” to record calibration.
