SPECIMEN HEIGHT
The specimen height is displayed on the LED at the top left corner
of the control unit. Always calibrate the specimen height after
changing the target pressure. If calibrating the height, angle, and
pressure, calibrate the pressure first. Then, calibrate the angle of
gyration. Calibrate the specimen height last.
Clean the turntable and loading head before calibrating the
specimen height.
After pressing 〈2〉 at the Calibration menu (see page 3-3), the
control unit prompts for height of the height calibration standard.
The height and serial number are stamped on the side of the
standard. Enter the standard height to the nearest hundredths and
press 〈ENTER〉.
NOTE
Cleaning and centering the puck and standard is very
important when calibrating the specimen height.
Place a clean puck, with the small side down, in the center of the
turntable. Put two specimen papers on the puck. Place the height
standard on the puck. Close the chamber door. To start the height
calibration, press 〈RAM DOWN〉.
After lowering the loading head onto the standard, the compactor
raises the loading head slightly. The compactor calculates the
system pressures, then lowers the loading head back onto the
standard. After lowering the loading head, the compactor calculates
the standard height. This calibration takes about 75 seconds. After
calibration, the system will verify the height of the standard and
display the result. The difference should be less than 0.05 mm.
