User method list, switch off all methods
The program structure requires that the method list must have at
least one active (switched-on) method. For this reason, the
photometer activates the first method on the list automatically.
User concentration method
It is possible to enter and store up to 10 user concentration
methods. This requires 2 to 14 standard reagents of known
concentration and one blank (deionised water or reagent blank
value) are needed for this. The standard reagents should be
measured with increasing concentrations and from the brightest
to the darkest colouration.
The measuring range for "Underrange" and "Overrange" is
defined with -2600 mAbs* and +2600 mAbs*. After selection of a
method, the concentration of the lowest and highest measured
standard is displayed as measuring range. In order to achieve
very exact results, the operation range should be within this
range.
*) 1000 mAbs = 1 Abs = 1 E (displayed)
Entering a user-concentration method
Press the [Mode] key.
Press the [Shift] and [6][2] keys.
Confirm with the
key.
This display appears.
• To display only one method in the method
selection list, press the [Shift] and [1]
keys.
• To keep the valid method selection list,
press the [Shift] and [0] keys.
The photometer returns automatically to the
"Mode" menu.
Press the [Mode] key.
Press the [Shift] and [6][4] keys.
Confirm with the
key.
Entry procedure:
This display appears.
To enter a method number in the range from
850 to 859, such as [Shift] and [8][5][0],
press the number keys.
Confirm with the
key.
Note:
If the entered number has already been
used to save a concentration, the display
shows the query on the left.
• To return to method number query,
press the [Shift] and [0] or [Esc] keys.
• To start the entry mode, press the [Shift]
and [1] keys.
Enter the required wavelength by pressing
the appropriate number key, such as [Shift]
and [2] for 560 nm.
