4. Configure the settings shown in the table below.
Calib.Valve: Online Side
Pump Valve: Pump Side
Pump: Off
Lamp: Off

5. Make sure that the sample liquid is flowing to the online side, then set [Pump] to [ON].
6. Wait 5 minutes while checking the conductivity value.
Continue flowing the sample until the conductivity value becomes constant.
NOTE: If the conductivity value fluctuates significantly (approx. ±0.1 μS/cm or more every 5 seconds), there may be a leak somewhere in the flow line and bubbles may have entered. Check the flow line. It you are unable to correct this problem even after checking the flow line, contact your Shimadzu representative.

5. Prepare four vials of pure water and load them into the vial sampler.
NOTE:
• See "Using the Vial Sampler" before loading the vials into the vial sampler.
• Use pure water with a TOC of less than 100 μg/L. "Preparing the Blank Water".
• Use pure water with a TOC of less than 100 μg/L. "Preparing the Blank Water".

6. Set [Vial Sampling Unit] to [V4Valve].
NOTE: After finishing the operations for [V4Valve], return to this step and perform the same operations for [V3Valve], [V2Valve], and [V1Valve], in that order.
NOTE: After finishing the operations for [V4Valve], return to this step and perform the same operations for [V3Valve], [V2Valve], and [V1Valve], in that order.
7. Set [Pressure Pump] and [Pump] to [ON].
NOTE: Perform this operation so that both items are set to [ON] within a few seconds of each other. If only [Pressure Pump] is set to [ON], water leakage may occur.
NOTE: Perform this operation so that both items are set to [ON] within a few seconds of each other. If only [Pressure Pump] is set to [ON], water leakage may occur.
If only [Pump] is set to [ON], bubbles may enter the flow line.
8. After setting [Pressure Pump] and [Pump] to [ON], check the conductivity value.
Continue flowing the sample until the conductivity value becomes constant.
NOTE: If the conductivity value fluctuates significantly (approx. ±0.1 μS/cm or more every 5 seconds), there may be a leak somewhere in the flow line and bubbles may have entered. Check the flow line. It you are unable to correct this problem even after checking the flow line, contact your Shimadzu representative.

9. Return to step 4, perform the same operations for [V3Valve], [V2Valve], and [V1Valve], and check the conductivity value for each.
