DOT600 Roadbed Water Content Meter
Place the wrench on the compression nut and rotate clockwise. Compress the
sample to a desired pressure (PSI), displayed on the logger screen.
Do not compress sample beyond 45 PSI. CAUTION
When sample is compressed remove wrench from compression
nut and place on foam away from the compression chamber.
Failing to do so will create interference with the magnetic
positioning sensors. NOTE
Sample elasticity will require some time for the sample to
compress (~30 sec to 1 min). As the sample compacts the
pressure will decrease and the compression may need to be
adjusted. NOTE
