(HPLC) Abnormal pressure value of Solvent Delivery Module

(HPLC) Abnormal pressure value of Solvent Delivery Module. Zero adjustment of pressure sensor.
Category : 

Answer

Zero adjustment of pressure sensor.
1. Set to [ZERO ADJUST] in the [CONTROL] group.
  * For LC-20A / 30A, [ZERO ADJ]
2. Open the drain valve to remove pressure completely.
  * For LC-40B X3/XR, the zero value of the pressure sensor of both A and B pumps is set at the same time, so open both drain valves.
3. Press [Enter].
 
If the pressure value is not constant, the pressure sensor may be defective, contact a Shimadzu sales or service representative.
