6500 Series
6510- Main pressure transducer overrange detected.

6511- Sample transducer (number) overrange detected.

6512- Po transducer (number) overrange detected.

6513- Hardware pressure overrange detected.
Cause: A manifold pressure over 1000 mmHg was detected by the hardware.
Action: Observe caution when operating the analyzer manually. If the problem
persists, contact your service representative.
6516- Sample pressure greater than (mmHg) is not allowed.
Cause: An absolute pressure greater than (pressure) mmHg was attained that
exceeded the specified maximum manifold pressure.
Action: The analysis was canceled. All previously collected data were stored.
6517- (Unit [number]) Total volume dosed greater than (volume) cm3 is not allowed.
Cause A:
More than (volume) cm
3
has been dosed onto the sample, possibly due
to leaks in the system.
Action A: Perform leak checks on the system. Refer to Appendix D,
TESTING
THE ANALYZER FOR LEAKS
, page
D-1
.
Cause B: The value for the Po may be too low, causing the instrument to mistake
condensation for actual adsorption.
Action B: Change the analysis variables to directly measure the value of Po dur-
ing the experiment.
Cause C: The amount of sample you used may be too large. Multiply the max-
imum value from the Volume Adsorbed column of the Isotherm Report
by the sample weight. If the result exceeds (volume) cm
3
, the amount
of sample is too large.
