n Checking the flow rate《FLOW CHECK》
When checking operation, connect a resistance tube to the pump outlet to create 5 MPa
to 10 MPa pressure during delivery.
According to your measurement method, measure the flow rate by following the
instructions below.
Set Value Measurement Method
0
The flow rate is measured based on the time that was required to deliver
the specified volume. (volumetric method)
1
The flow rate is measured based on the weight of water delivered in the
specified time. (gravimetric method)
2 A flow meter is used for measurement
Before measurement, make sure that the compressibility correction parameter of
the solvent is correctly set.
"Setting the compressibility of solvent《COMP》" P.32
To use the volumetric method
1
Set the flow rate and start delivery.
2
After confirming the delivery stabilizes, measure the time required for the
solvent to accumulate to 5 mL in a measuring flask.
3
In the [FLOW CHECK] screen, press
[Enter].
4
In the measurement method selection
screen, input "0".
5
Input the measured flow rate.
The value can be set between 0.1 mL/min
and 3.0 mL/min.
