DetAPCn reference gas set point not reached [Error Code:2424 2425 2426 2427]

Cause¶

The pressure or flow rate may not have reached the set value for the following reasons:

• The gas supply pressure is insufficient.
• There is a leak at the pipe connection.
• The resistance of the supply piping is high (the connected piping is long or the inner diameter of the piping is narrow).

Solution¶

• Check that the gas main valve is open.

• Check that the gas supply pressure is within the range below.
  

  

  

• Check that the supply pressure is sufficient for the reference gas to flow.
  

  

  

• Check for any looseness or leaks at the pipe connections.

• Contact your Shimadzu service representative to check the inner diameter and length of used piping.
