Essential Steps
If you have a Dual-syringe 402, install the tubings
as described in Chapter 3, page 3-5. You must
connect 4 pieces of tubing: inlet (reservoir), Valve to
Tee-junction, transfer (probe), and waste.
Switch-on
1) Switch on your 402 (the power switch is on the
back panel): the indicator light on the front panel
comes on, the keypad is illuminated, and briefly
displays messages giving the software version
numbers, Initialization Screen 1, for example. This
is followed immediately by Initialization Screen 2.
2) Put the end of the probe into any container
suitable for waste liquids, then press the white
key immediately below OK.
The syringe-piston operating-rod(s) move to their
uppermost positions, while the Homing Screen is
displayed on the keypad.
3) Then the Start-up Screen is displayed. After
switching on, Method 1 is always shown on the
screen even if the file has not yet been created
(New). [When you want to run or edit any other
file, you must first key in its number, then press
ENTER.]
Four soft-touch keys are accessible from the Start-up
Screen: Conf (Configuration), Edit, Man (Direct
Manipulations), and File; the fifth ‘Run’ appears
after you save a Method file. They are called soft-
keys because they vary from screen-to-screen; you
must press the white key immediately below the
corresponding ‘label’ (e.g. Conf) in order to carry
out the desired action.
Pressing a soft-touch key leads you to a
series of screens containing menus and sub-
menus that enable to perform functions
related to the key pressed.
To operate your 402, you must use Conf,
Man, and Run. Five prefabricated Methods
(files 90-94, see Chapter 5) are supplied as
part of the software; however, you will often
want to use Edit to create your own Method
files.
