5. After cycle completes, in the “Last Dispense with Reference”, press

“Load”. The Data field should fill in with confirmation test results.

Confirmation Example

• Since “All Confirmation Alarms” was disabled, the data field shows

what the results would have been if the confirmations test was
enabled.

• The results show one test condition would have triggered an error.

• Pump shows “Ready” because alarms are disabled.
