MAN - BBR3 - REV: Original | E. Operation
WARNING: Be certain to perform ALL STEPS in the standardization menu for each of the senors
EXACTLY AS DESCRIBED. Failure to perform all steps of the standardization procedure may result
in incorrect or erratic operation of the BBR3.
1. Standardizing the Temperature (RTD)
NOTE: Before standardization, verify that the bath is set at your desired testing temperature.
a. From the Main Menu select the “Setup” button.
b. Verify the load frame is in the bath.
c. Allow temperature to stabilize for one to two hours after set point is reached.
d. After temperature has stabilized, select “Main Menu” and then press the “Standardization” button.
e. Select the “Temperature” button.
f. You will need a calibrated partial immersion reference thermometer suitable to ASTM 133C. Submerge the
thermometer into the liquid bath at the appropriate depth beside the RTD.
g. Leave the thermometer in place for a minimum of two minutes and note the temperature reading to the nearest
tenth of a degree (within 0.1⁰C).
h. Record this temperature in the field and select the “Finish” button.
2. Standardizing the Load (Load Cell)
a. Select the “Load” button from the Standardization Screen.
b. With the load frame in the bath, load the non-compliant beam into test position.
c. Using the zero regulator, adjust the load nose so it is slightly above the beam.
d. Press the “Tare” button.
e. Using the zero regulator, gently lower the load nose lightly onto the beam with minimal load (20mN ± 10mN).
Press the “Next” button.
f. Select weight A from the gauge kit and place it on the weight pan. Wait five seconds and press the “Next”
button.
g. Select weight B from the gauge kit and place it on top of weight A. Wait five seconds and select the “Next”
button.
h. Select weight C from the gauge kit and place it on top of weight B. Wait five seconds and select the “Next”
button.
i. Select weight D from the gauge kit and place it on top of weight C. Wait five seconds and select the “Next”
button.
