15.4 - Diluter
15.4.1 - Diluter system not sufficiently primed
Before aspirating, the diluent system must be free of air bubbles.
Select
Maintenance-> Prime -> Prime Diluent
, vacuum pump is on and system must be filled with Diluent. When
the diluent is priming, liquid should be seen flowing through the tube connection to the fill nozzle cap.
Occasionally when the diluter system is primed for the first time, air locks occur in the tubing and the diluter
will not self-prime. If this occurs, disconnect the luer fitting at the syringe and connect a syringe filled with
Diluent to the tubing and fill system manually.
1. Check pick-up tube at the Diluent bottle or cubitainer, it may be kinked.
2. One of the Diluent lines has become blocked or kinked.
3. Check if all tubes are still connected.
4. Check if the 2 tubes (ESRI070508) are still connected with the tubes ESRI070406.
5. Check if the 2 tubes positioned correctly in the pinch valve.
15.4.2 - Diluter errors
If the display shows dilution errors it indicates that the current sample has not been diluted correctly e.g.
-21% Diluent added to the sample. After the sample measurement the dilution rate will be printed as:
EDTA 079.
A (partly) blocked sample flow will be signaled by a time-out on the filling time.
