W96
Residual gas evacuates too
slow.
Time t1 > than the set evacuation time t_A.
Valve V30 does not open.
Fore pump defective
Wrong time setting for t_A. t_A < than the evacuation time of residual gas.
Wrong setting for the evacuation pressure p_B. Evacuation pressure not reached
within the preset evacuation time (p_B < residual pressure of test gas).
W97
Flooding of test sample takes
too long .
Time t1 > than the set flooding time.
Flooding valve V31 defect.
Wrong setting of the flooding time to reach the pressure p_A. (p_A = pressure of
Gross leak ). t_E < ventilation time
Wrong setting of pressure p_A, which has to be reached within specified flooding
time p_A > atmospheric pressure.
W98
Leak rate not stable enough
during the zero- delay time.
When reaching "Ultra", the readiness for measuring will be enabled for the
function I•ZERO „activated“, when a stable leak rate signal appeared during the
zero-delay time depending on the selected trigger.
False adjustment of the zero-delay time t_B..
Selected trigger 1 too low.
Background in the test chamber is too high.
W99
Pressure in the sample has
dropped below p_E.
During the measurement time, the filling pressure of the sample dropped below
the pressure drop trigger p_E.
Wrong setting for the pressure drop trigger P_E.
