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.

Essential Steps

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.
