￿Measure the quantity of fluid dispensed. The pump displays its calculated dose, based on previous calibration data. Use the UP and DOWN keys to adjust this reading to match the measured volume. Press ENTER. The pump displays the new head, tube and flow settings, and redisplays the main menu. Example fig- ures are shown here.

Note: If the pump has been set to display flow rate in units of mass (see 18.8 Flow units), as in this example, the pump displays a screen allowing you to confirm the specific gravity of the duty fluid immediately before the final press on ENTER.

Note: Always recalibrate after changing pump tubes, fluid, or any connecting pipework. It is also recommended that the pump is recalibrated periodically to main- tain accuracy.

Note: If the pump power is cycled while flow rate is displayed, calibration is lost and a warning is displayed.
