Operation - Standard Use

‘Homing ...’ appears on the screen until the syringe(s) have returned to their uppermost (home) positions, during which time any liquid contained in the transfer-tubing is expelled from the probe-end. After this the Action Screen reappears.

Press ESC to return to the start-up screen for the current file.

Whenever you see ‘Homing’ on the screen, the syringe piston(s) are returned to their uppermost position(s). As a result, some (or all) of the liquid contained in the transfer-tubing will be expelled from the probe-end. You must ensure that the probe end of transfer-tubing is already in a suitable waste container.

Essential Steps

Running a Method (Run)

Introduction

The Run soft-key appears, after you have entered your Method. Press Run to start the Method cur- rently shown on the screen (at the first task, in this example Dispense).

If you want to run a different program, you must key in its file number and press ENTER, before pressing Run.

After pressing Run, a series of in run screens appears. During the run, you must follow the instructions on the screen, and press the command button on the probe when prompted to do so by the command light on the probe.

You press the command button on the probe to aspirate and to dispense:

-a steady light means you are going to aspirate or dispense liquid,

-a flashing light means you are going to aspirate air.

When you have finished, or wish to change pro- grams, press STOP, to instantly halt the program.

Pressing STOP

When you press STOP, the motion of the syringe(s) ceases and the Abort Screen appears. Press Proceed, when you want to continue with your Method.

Press Abort, when you want to stop. Unless the syringe(s) are already at their uppermost (home) positions, Initialization Screen 2 reappears.
