What do these products do in this instrument?
Bubble and pressure detection: identify field fluid-path supply anomalies
Provide bubble or pressure signals in compatible liquid branches. The controller associates low-liquid, blockage and washing states. Confirm actual sample renewal after recovery before releasing measurements according to the method.
ABD provides bubble or liquid-state signals for defined tubing; PDM5 provides pressure information at a defined location. Configure module, position and action window separately; the controller associates affected samples or tasks.
Match sensing locations to specific fluidic problems
Bubble modules report bubble or liquid state in defined tube segments; pressure modules report pressure at defined positions. Before selecting mounting points, define the phase and abnormality to observe: aspiration, delivery, source depletion or branch-load changes. Associate sensor positions with affected samples, cuvettes or stations.
Connect signals, action windows and recovery conditions
The same signal may mean different things at different valve positions or operating phases. Record normal ranges and faults with actual liquids, tubing and sequences. The controller combines action timing, confirmed delivery status, volume records and sample identity to pause, review or recover; one pressure change cannot directly identify a blockage location or specific cause. Distinguish measured, estimated and unknown volumes; completion of a command does not prove actual liquid delivery.
Translate actual branch conditions into configuration requirements
| Condition | To confirm |
|---|---|
| Installation conditions | Specify tubing dimensions, liquid, sensing location and branch to observe. |
| Timing and baseline | Record valve positions, pump actions, normal changes and fault-detection windows. |
| Abnormality handling | Associate affected containers with confirmed delivery status and volume records; define conditions for review, continuation or re-execution. Distinguish measured, estimated and unknown volumes; completion of a command does not prove actual liquid delivery. |
| Operation | Specific operating conditions |
|---|---|
| Field reagent supply and recovery after bottle changes | Actual reagent-transfer branch, formulation, stored volume, point-of-use demand, backpressure, bottle changes and priming destination |

Field reagent supply and recovery after bottle changes
Cabinet temperature, bottle-change interval and priming affect supply recovery. Assess field-source conditions separately from individual doses inside the cabinet, then evaluate the first reaction according to the method.
Confirm product roles in actual operation
| Operation | Measurements and observations | Priority checks |
|---|---|---|
| Field reagent supply and recovery after bottle changes | Measure actual supply at the use point, empty-source interlocks, composition refresh after bottle changes and first-cycle recovery. Validate reaction metering separately within the analytical unit. | An empty source, bubbles, old-reagent residue or excessive transfer load can interrupt supply at the use point. |
Compare field and received samples for representativeness. Measure actual refresh and recovery after maintenance.
Can dispensing be repeated immediately after bubbles or abnormal pressure are detected?
First establish whether partial delivery has occurred and which container is affected. Immediate repetition may double-dose it. Act on the actual state and recheck the first cycle after recovery.
Nominal volume divided by flow estimates transport time; it does not establish complete sample renewal or representativeness.
