Measure the quantity of fluid dispensed. The pump displays its calculated dose,
based on previous calibration data. Use the numeric keys to adjust this reading
to match the measured volume. Press
ENTER
. The pump briefly displays the
new head, tube and flow settings, and displays the main running screen.
Example figures 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
: if calibration was entered by pressing
CAL (SHIFT, 8)
from the main running
screen,
the pump redisplays the main running screen and restarts immedi-
ately without waiting for a further command
.
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.
