Self-Test
Each time it is turned on, the MicroFlo automatically runs a self-check to verify system
components. It can also be run from the Utility menu.
The self-check verifies movement of the dispense arm and plate carrier.
Startup: When the test completes successfully at startup the Main Menu appears. If
the test fails, the dispenser will “chirp” and display an error code. Jot down the error
code and turn off the dispenser. Fix the problem and turn it on again.
Utility Menu: When the test completes successfully from the Utility menu a “passed”
message is displayed. If the test fails, the dispenser will “chirp” and display an error
code. Press the
Enter key, look up the Error Code and fix the problem. Re-run the
SLFCHK.
Error Codes are listed in Appendix A.
