f. The modulus reported should be within 10% of the modulus of the Confidence Beam, as listed on the
verification conformance form.
g. If the measurement is within 10% press “OK” then the “Verification Complete” button.
h. If the measurement is more than 10% press “OK” and then the “Standardization Required” button.
i. Press the “Next” button to move on to the next section.
8. Verifying the RTD
a. You will need a partial submersion calibrated reference thermometer suitable to ASTM 133C.
b. With the load frame in the bath, immerse the calibrated reference thermometer into the bath close to the RTD.
c. Compare the measured system temperature to the reference thermometer
d. If the temperatures differ more than ±0.1⁰C, press the “Standardization Required” button and then press
“Next”.
e. If the observed temperatures are within ±0.1⁰C press the “Verification Complete” button and then press “Next”.
9. Verifying the Load Shaft Alignment
NOTE: This only needs done every six months. To skip this step, press the FINISH button
without pressing any of the radio buttons.
a. For this process you will need a strip of white paper 12.7 mm x approx. 25 mm long, and a strip of carbon
paper of the same or similar dimensions.
b. Place the white paper strip on the non-compliant beam and secure with tape.
c. Remove the load frame from the liquid bath and set it in an upright position on a flat surface.
WARNING: Do not lay the load frame flat with the load nose attached. This will damage the load
cell.
d. Place the non-compliant beam on the sample supports, with the white paper facing up.
e. Place a small section of carbon paper over the white paper with the dark side facing the white paper.
f. With the air pressure applied to the air bearing, gently press the shaft downward causing the load nose to
make an imprint through the carbon paper onto the white paper.
g. Remove the carbon paper and measure the distance from the center of the carbon imprint to each sample
support using vernier calipers.
h. If the difference between the two measurements is 1.0mm or less, press the “Verification” button followed by
the “Finish” button.
i. If the difference between the two measurements is more than 1.0mm, press “Standardization Required” and
