Example:
For flowrate 1 ml/min resp. 5 ml/min resp. 10 ml/min is selected volumetric flask
with volume 10 ml resp. 50 ml resp. 100 ml.
Press ENTER to enter menu item
FLOW AUTO
. At the screen heading is displayed 1/6 with
action instructions. After completing given action proceed to the following step.
1/6) Start the pump by pressing
PUMP
. Process proceeds to the following step.
2/6) Parameters measured by the unit are displayed
– time, volume, pressure. Let the unit to
stabilize for approximately 1 minute. Press
ENTER
to continue.
TIME --- ( --- ml); PRES xx (yy) MPa (xx
…actual pressure, yy…pulsation)
3/6) Unit is prepared for start by pressing
ENTER
. At the same time start capturing mobile
phase in the volumetric flask.
4/6) Time and volume start countdown. After filling volumetric flask, press ENTER.
5/6) Pumping stops, time and volume countdown stops. Display shows
VCNT…volume
measured by the unit during measuring (ml);
VREF…reference volume (ml), filled in
according to used volumetric flask; (xx %)
…deviation from previous calibration.
After pressing ENTER is calibration of flowrate (
FLOW AUTO)
finished. After pressing
ESC,
it does not finish.
