Standard Operations

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.

5.4.6.1 Change 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.

 

The current result and all further measurements will be displayed in 
the new chemical form.

5.4.7 Run a reagent blank

Some of the stored tests/methods include the "Reagent Blank" 
function. This enables the reagent blank value to be measured and 
then taken into account in calculating the measurement result.

Measurement/analysis of a reagent blank:

1.

Prepare the test/method in accordance with the (working) 
procedure. Instead of a sample, deionized water is used to 
determine the reagent blank value.

2.

Select the test. If required by the (working) procedure, insert 
the cell with deionized water into the cell compartment. Press 

Zero

.

3.

Insert the prepared sample cell into the cell compartment. 
Press 

Read

. The result is displayed.
