If the System pressure differs from the Load Cell pressure by
more than 10 kPa, or if the System pressure is not within 600
18 kPa, check all cable connections and the position of the
load cell and puck. Repeat the calibration. If repeated attempts
to calibrate the pressure fail, contact your Troxler
representative.
Press ENTER. The compactor stores new calibration
constants based on the System and Load Cell values. It then
lowers the ram and returns to the Calibration menu shown on
page 4–5.
Open the chamber door and remove the calibration load cell and
pucks. Unplug the dc charger from the electrical outlet, and
disconnect the load cell from the dc charger and control unit.
Return all parts to the Performance Verification Kit case.
SPECIMEN HEIGHT
If calibrating the height and pressure, calibrate the pressure first.
Then calibrate the specimen height.
NOTE
For optimum performance—if operating the compactor
at a ram pressure other than 600 kPa—calibrate the
specimen height and gyration angle after changing the
ram pressure.
NOTE
Before calibrating the specimen height, clean the ram
head, lower carriage plate, upper carriage assembly,
and upper puck plate with de-greaser. Failure to do so
may cause the height calibration to be inaccurate.
