Hach DR 5000 5.4.5 Set the dilution factor

45

Standard Operations

5.4.4.1 Take single wavelength measurements (single reading)

1. Insert the blank cuvette into the cuvette/sample cell holder.

Press Zero.

Note: The Read key is only active after the zero measurement has

been carried out.

2. Insert the sample cuvette into the cuvette/sample cell holder.

Press Read.

Note: For data storage, see section 5.3.2 on page 38.

5.4.4.2 Take single wavelength measurements (continuous readings)

1. Insert the blank cuvette into the cuvette/sample cell holder.

Press Zero.

Note: In the reading mode ”Continuous“ only the Zero key is shown to

start the reading. The reading sequence is started automatically.

2. Insert the sample cuvette into the cuvette/sample cell holder.

3. Press Options and then the Store icon to store the displayed

data in the Data Log.

Note: For data storage, see section 5.3.2 on page 38.

5.4.5 Set the dilution factor

The Dilution Factor function is used to calculate the original

concentration of a sample that has been diluted by a known ratio.

For example, dilution factor can bring the analyzed concentration

within the test range.

1. Press Options>More…>Dilution Factor.

The number entered at the dilution factor prompt will be

multiplied by the result to compensate for the adjustment.

For example, if the sample has been diluted by a factor of 2,

enter 2. The default setting of the dilution factor is turned off.

2. Press OK to confirm.
