Operation - Advanced Use

5

This is realized using the 402 by pressing the probe’s command button with increasing rapidity as you approach the neutralization point. Care must be taken in selecting the dispense flow rate.

•Press Titrate, Titrate Screen (1) appears. Select either reservoir or probe as the source using the Chge soft-key, then press ENTER to confirm your choice.

•Press the Next soft-key, key in the volume to aspirate, then press ENTER, Titrate Screen (2) appears. Normally, you would aspirate sufficient liquid for several titrations.

•Press the Next soft-key, Titrate Screen (3) appears.

•Follow the instructions given on the screen; you press the command button on the probe to aspi- rate and to dispense, when prompted to do so by the command light on the probe:

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

-a flashing light means you are to aspirate air via the probe.

Read the volume on the screen, Titrate (4) Screen (for example), after completing each titration.

Conclude the current titration by pressing STOP or End (see Prime for details).

Tasks - Detailed Descriptions

Your Method may consist of one or more of the following tasks. Each task consists of a pre-defined protocol, from which you select the required mode of operation, and into which you insert the required parameter values.

In-run Prompts

For optimization purposes, all volumes and flow rates, which can be entered as parameters in a task, can be defined as In-run Prompts. When editing the task, you key in a value, and then a question mark (?), the corresponding flashing value has to be validated or changed before the Method runs. It is not necessary to re-edit the method to modify the chosen parameter.
