Testing multichannel pipettes
How to do it
Press the 'Start/Execute'
button. The 'Start' submenu
is called up.
Press the 'Start/Execute'
button.
The test is begun, and
the test pressure is set (in
progress...)
Shortly before the end of the
preparation period, the LED
light shines 1 time red and 1
time green, then the progress
bar appears and the sys-
tem automatically starts the
measurement. At this time,
the pipette button is pressed
down evenly 2-3 times. The
piston must return the initial
position before the measure-
ment is finished! The prog-
ress bar graphic indicates the
remaining time and the cur-
rently achieved vacuum.
The LED indicator blinks or-
ange.
After the test is finished, the
display indicates the leak
rate that was determined and
whether the system passed
the test.
The 'Start/Execute' button
can be used to repeat the
test, or the test can be
continued with the next 4
channels.
Turning the select knob leads
directly to the Main Menu.
