DAMCn makeup set point not reached[Error Code:2272 2273 2274 2275]

The pressure or flow rate may have not reached the set value due to the following reasons. 

• The gas supply pressure is insufficient. 
• There is a leak at tubing connections. 
• The resistance of supply tubing is large (since the tubing connected is long or its inner diameter is small).

• 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 makeup gas to flow.
• Check that no tubing connections are loose and there is no leak.
• Contact your Shimadzu service representative to check the inner diameter and length of used tubing.
