TE-BBR Instruction and Operation Manual
Using a continuity tester or ohmmeter, check each set of pins in the cable for continuity. Replace the
cable if it is faulty.
Internal Wiring
The temperature reading issue could be in the connector, or the wiring leading to the connector.
Remove the front panel to the Load Unit and inspect the leads to the thermistor connector to verify
they are secure.
Confidence Test Failures
Problem: The confidence test fails repeatedly.
Solution(s): Check software settings for the thin beam thickness as follows:
1. Choose Setup from the BBRw Main Menu and click Instrument Setup.
2. Select the Beam Dimensions tab from the property sheet.
3. Measure the thickness and width of the thin steel beam used for the test and compare the
measurements with the recorded value for Thin Beam Thickness and Width.
4. If the setting is incorrect, enter the correct value in the appropriate field and click OK to save
the new value. If the setting is correct, recalibrate for Force, Deflection and Compliance (see
Calibration section for instructions).
5. Rerun the confidence test.
Level the BBR
If the TE-BBR is not level, the weight platform may rub against the steel bar used to prevent rotation
of the platform. The resulting friction produces an erroneous measure of the steel beam modulus.
To level the TE-BBR, place the bubble level (supplied with the instrument) on the Load Platform of
the Load Frame and adjust the legs under the Control Unit to level the instrument. The supplied
bubble level is pictured in Figure 24.
