TE-BBR Instruction and Operation Manual
Calibration
To provide accurate readings from the thermistor probe, it is necessary to calibrate the probe
periodically with a calibrated thermometer.
Thermistor Probe Calibration Procedure
1. Load the BBRw software and select Calibrate > Thermistor from the BBRw Main Menu or use
the Thermometer icon.
2. Enter the current temperature of the bath to the nearest 0.01 °C as indicated by a separate
calibrated thermometer and click OK.
LVDT and Load Cell Calibration
It is vital to calibrate the LVDT (Linear Variable Differential Transducer) and Load Cell in order to
expect accurate readings for the output.
1. Select Calibrate from the BBRw Main Menu.
2. Select Force, Deflection and Compliance from the calibration options.
3. Follow the on-screen prompts to complete calibration.
A cylindrical metal gage block is provided for the LVDT calibration. Refer to Figure 17. This block is
placed to the left of the load platform on the small pin provided so the block can be rotated easily. A
6.35 mm (¼") thick stainless steel beam and four 100 gram weights are supplied for the calibration.
At the end of the calibration run, remove the weights from the load platform, and the 6.35 mm (¼")
steel beam from the bath.
