Agilent 7500 Series ICP-MS Hardware Manual 5-19
• The vacuum tubing has failed (the tubing is off, or a leak is caused by an
incomplete seal such as a pin hole or a defective O- ring).
• A drop of water was introduced into the vacuum chamber.
1121* Error: Pirani gauge (BK) malfunction (Open).
There is a fault in the interface of the Pirani gauge or in the Pirani gauge
control circuit (In Analysis Mode).
1121* Error: Pirani gauge (IF/BK) malfunction (Open).
There is a fault in the Pirani gauge (IF/BK) or in the Pirani gauge control circuit
(In Analysis Mode).
1122 Error: Penning gauge (AN) malfunction.
The Penning gauge works abnormally (When the instrument is changing from
Shutdown Mode to Standby Mode).
The Penning gauge may be recovered if you change to Shutdown mode, loosen
the vent valve, and release the vacuum chamber to the air.
1123 Error: Vacuum pressure (AN) time out, vacuum too high to enter to
Standby Mode.
The instrument cannot transit to Standby mode because the vacuum pressure
(AN) was not managed below the limit within the prescribed time (When the
instrument is changing from Shutdown Mode to Standby Mode).
Check the pressure of the analyzer chamber. The following causes are inferred.
Also this error is generated when a vacuum pump is not used for a long time. In
this case, turn on the vacuum ON again.
• The vent valve is not closed or the seal is incomplete.
• The cover of the vacuum chamber is not closed or the seal is incomplete.
• The power of the rotary pump is not connected or the breaker is OFF.
• The rotary pump oil level is low or the oil is dirty.
• There is a leak in the gate valve.
• The vacuum tubing has failed (the tubing is off, or a leak is caused by an
incomplete seal such as a pin hole or a defective O- ring).
• The vacuum pressure (AN) cannot be measured correctly due to a fault in
the Penning gauge.
• There is a fault in the turbomolecular pump.
• Some of the parts in the vacuum chamber are not completely dry.
1124 Error: Vacuum pressure (AN) time out, vacuum too high to enter to
Analysis Mode.
Vacuum pressure (AN) was not managed below the limit within the prescribed
time. Therefore, the instrument could not transit to the Analysis mode (When
the instrument is changing from Standby Mode to Analysis Mode).
