Zeroing the Channels
Each channel must be zeroed before every test. This gives the software a
starting point with which to calculate the percentage of swell during the test.
1. Click the “Zero/Start/Stop” button.
2. Repeat the following steps for each channel to be tested:
a. Enter a test name and any comments.
b. Place two screens into a fully-assembled cup. Place the cup on the
magnetic stirrer so that the LVDT spindle is resting on top of the
transfer stand. Check the box in the “Zero” column next to each cell to
be tested.
c. Click the “Apply” button to zero the channel. Make sure the “Corr Dist
(in)” field reads 0.000.
