Calibration
To determine if a cell needs to be calibrated, zero the transducer (see page
8) and then place the calibration block underneath the LVDT rod. If the
corrected distance does not correspond to the marking on the calibration
block, the cell should be calibrated.
1. Place an empty sample cup upside down on the stirring hot plate. Make
sure the rod of the LVDT is resting on the bottom of the cup.
2. In the Swell Meter software, select “Calibration” from the “Options” menu.
3. Choose the cell you want to calibrate and click the “Calibrate Cell” button.

4. Adjust the LVDT head up and down on the stand until the voltage reads 0.
Tighten the locking nut and use the micrometer for fine adjustments.
5. Place the calibration block (#150-80-101) on the surface of the cup and
rest the LVDT rod on the portion of the block that reads .20. Be sure to let
the reading stabilize before continuing.
6. Click “Accept”.
7. Repeat steps 5 and 6 with each level on the calibration block.
8. After measuring all five levels, click the “Save” button to finish.
