Preparing the analyzer
Always take suitable safety measures as described in the Operator’s Manual.
1 Check that the container for highly concentrated waste is clean and empty.
2 Check for any leaks inside or around the instrument.
3 Check that the cell covers, pipetter probes, ISE sipper nozzle, and the rinse nozzles are clean.
If a trouble occurs, take the necessary remedial action.
Starting the analyzer
1 Switch on instrument. When the automatic power up is specified in the analyzer software, the pipe
function will be executed automatically.
2 Switch on control unit computer.
3 Switch on water supply.
4 Logon to the analyzer software using your operator ID and password.
Note: When the analyzer is in sleep mode, it starts up automatically by using the sleep pipe function
(Power Up Pipe with starting time).
