Press [1], [5], [ . ], [0] and [Enter].
The maximum pressure is set to 15.0 MPa.
The allowable maximum pressure is 130 MPa for LC-40D X3 and 70 MPa for
LC-40D XR CL. When connecting the instrument with other equipment, set the
maximum pressure to the lowest allowable maximum pressure of the equipment.
"Setting the maximum pressure limit during pumping《P.MAX》" P.31
3.1.5
Setting Minimum Pressure Limit
The purpose of the minimum pressure limit
is to prevent a pressure drop which can
occur as a result of the following
situations:
•
When
the mobile phase runs out, air will
be pumped through the flow lines resulting in a pressure drop.
• When a leak occurs in the flow lines, a pressure drop may be observed.
If the pressure is lower than the minimum
pressure limit after one minute during
pumping, the flow stops automatically.
Then the error message will be displayed
with the alarm sound.
n Setting example
The following is an example to set the minimum pressure [P.MIN] to 2.0 MPa.
1
Press [→] three times on the initial screen.
The PARAMETER setting group is displayed.
2
Press [
↓] once and on the [P.MIN]
screen, press [Enter].
The cursor blinks at the input position
indicating that [P.MIN] can be input.
