13-10 DSX™ System Service Manual
To Verify Dispense Pump Calibration (Checking the Dispense Accuracy):
1 Select a Pump letter.
2 Purge the washer until it is visually verified that no air bubbles are present in the
fluid line between the dispense bottle and wash head.
3 Follow protocol instructions.
4 The program prompts the user to weigh a clean and dry microtiter plate. After the
washer dispenses liquid into the plate, the user is prompted to weigh the plate
again. The software provides a pass or fail result for the verification.
Note: The Dispense Accuracy test protocol tests the dispense accuracy of the
DSX washer module for a volume of 300 µL per well. To pass, the error must be
less than or equal to ± 10%.
