TROUBLESHOOTING AND MAINTENANCE AccuPyc 1330
CALIERR: Underrange
NN/ZZ runs completed
Cause:
Action:
Apressure underrange occurred during the first pass of calibration because an
error occurred in the pressure measurement electronics.
Call a Micromeritics Service Representative.
CAL2ERR: Eq failure
NN/ZZ runs completed
Cause:
Action:
The calibration standard failed to equilibrate in I {)()() seconds during the second
pass of calibration.
Check the system for leaks as described under Checking the Cell and Expan-
sion Chambers for Leaks later in this chapter.
CAL2ERR: Fill failure
NN/ZZ runs completed
Cause:
Action:
There was insufficient pressure to allow filling within five minutes during the sec-
ond pass of calibration.
Open the tank valves if shut, increase the regulator pressure or, if there is insuffi-
cient helium in the tank, obtain a new tank of helium.
CAL2ERR: Overrange
NN/ZZ runs completed
Cause:
Action:
Cause:
Action:
Apressure overrange occurred during the second pass of calibration because the
regulator pressure is set too high.
Adjust the pressure so that it is equal to the higher of the two fill pressures speci-
fied in the analysis parameters plus 2.0 psig.
Apressure overrange occurred during the second pass of calibration because an
error occurred in the pressure measurement electronics.
Call a Micromeritics Service Representative.
CAL2ERR: Underrange
NN/ZZ runs completed
Cause:
Action:
5-6
Apressure underrange occurred during the second pass of calibration because an
error occurred in the pressure measurement electronics.
Call a Micromeritics Service Representative.
