5.4.7 Set the chemical form

Some Stored Programs allow a variety of chemical forms to be selected.

Press the unit (e.g. mg/L) or the chemical representation of the evaluation form (e.g. Al3+). A list of available evaluation forms is displayed. Select the required form by pressing the corresponding entry in the list.

Note: When the program is exited, the evaluation form reverts to the standard setting.

An alternative way of changing the standard setting:

1.Press Options>More>Chemical Form.

2.Select the Chemical Form.

Note: The stoichiometric conversion of the measurement result is carried out automatically.

Note: The selected Chemical Form will appear on the display. Test results will be calculated and displayed in this chemical form.

5.4.7.1Change of the default setting of the chemical form

1.Insert the sample cuvette or blank (depending on the working procedure) into the cell compartment.

2.In the result display, press Options>More>Chemical Form.

3.A list of available evaluation forms appears. Select the new default setting.

4.Press Save as Default.
