This error occurs if you try to calibrate the pressure slope when the pressure is
less than 3 MPa (500 psi).
To troubleshoot:
1. Verify that the pump is on and that the flow rate is at the rate required for
the application.
2. Verify that the pressure gauge is working correctly.
3. Verify that the number and type of installed backpressure coils is correct
(see “Insufficient conductivity cell backpressure” on page 58 ).
4. Check for liquid leaks (see Section 4.2 ).
These errors occur when the eluent bottle contains less than the volume
specified in the error message.
To troubleshoot:
Chromeleon determines the eluent usage by monitoring the flow rate and the
length of time the pump is on. After filling the eluent bottle, be sure to use the
Eluent Fill Volume slider on the Chromeleon ePanel to reset the volume of
liquid in the bottle. As the eluent is depleted, the volume displayed on the
ePanel is updated.
Pump pressure slope calibration error.
Remaining eluent below 100 mL.
-or-
Remaining eluent below 200 mL.
For the Eluent Fill Volume to be accurate, you must enter the level
each time the bottle is filled. The Dionex Easion does not
automatically detect when the bottle is filled, nor when it is emptied.
