HW_ERR: Calibration
could not be read
Cause A: You entered a value for the calibration standard that was less than 10%
of the nominal cell chamber volume. Resulting data may be inaccurate.
Action A: Be sure you enter the value recorded on the Calibration Standard case.
Cause B: You used an inappropriate calibration standard for the nominal cell
chamber.
Action B: Use a calibration standard of sufficient size (calibration standards are
available from Micromeritics). The calibration standard should occupy
at least 10% of the nominal cell chamber volume and the more nearly
filled the cell is, the better the calibration.
Cause: There was not enough sample placed in the sample cup to give an
accurate reading.
Action: Rerun the sample using enough material to occupy the maximum
amount of the nominal cell chamber volume.
Cause: The calibration information could not be read from the command or
analysis module.
Action: Close the application and cycle power on the instrument. Contact your
service representative if the problem persists.
