assistance.
This error occurs if an instrument method includes a BeginSPSamplePrep
command but not an EndSPSamplePrep command. Both commands are
required to define a sample preparation command block. See “Notes” on
page 92 for more information.
To troubleshoot:
1. Open the instrument method.
2. In the Script Editor view, add the BeginSPSamplePrep command before
the first sample preparation command.
This message occurs if the flow rate of the sample stream being monitored by
the flow sensor exceeds the upper limit.
To troubleshoot:
1. Verify the flow rate, using an external measuring device. If the flow rate is
normal, calibrate the flow sensor (see Section 10.10 ).
2. If the message reappears, the sensor may need to be replaced. Contact
Technical Support for Dionex products for assistance.
