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.
