Save icon
Depending on whether Instrument Setup > Data Log Setup > Auto Store: On or Off is selected,
the Save icon either calls up stored data or performs a manual save procedure.
% Trans/Conc/Abs
Switches from % transmittance to concentration or absorbance in reading mode.
Send Data icon
To send data to a printer, network drive, computer or USB memory stick (USB type A or Ethernet
port)
Timer icon
This functions as a stopwatch. It helps to make sure that the steps of an analysis are correctly
timed (e. g. reaction times, wait times, etc., can be exactly specified). When the specified time has
elapsed, a sound is emitted. The use of the timer has no influence on the reading program.
Dilution Factor Off/On
A corrective dilution factor can be entered in order to take account of certain properties.
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.
Note: During use of a dilution factor, the dilution symbol is shown on the display.
Standard Addition
This option enables the accuracy of the measurements to be checked. The procedural instructions
for test parameters contain a detailed explanation of how to use this function.
Standard Adjust:
Off/On
The procedural instructions for test parameters indicate whether a standard adjustment is
necessary and, if so, how to proceed.
Chemical Form
Some of the stored tests/methods allow selection of the chemical form and measuring range.
Reagent Blank: Off/On
Some of the stored tests/methods include the "Reagent Blank" function. This enables the reagent
blank value to be added to or subtracted from, the subsequent readings. The reagent blank value
shifts the calibration curve along the y-axis, without changing the shape or gradient of the curve.
The effect corresponds to a y-axis intercept of the calibration straight line. This is clarified by the
following formula: concentration =[conc. factor) x Abs] - (reagent blank)
Save as User Program
To store the selected parameters as a User Program, refer to
Multiple determination
This option allows multiple measurements of a sample.
Reading Mode
The "Reading Mode" function is available for some saved tests/methods.
Single Reading: A single reading is displayed when Read is pressed.
Continuous Readings: After the zero measurement, all readings are displayed automatically and
continuously.
Carousel 1 inch square: Optional measurement of carousel insert with up to 5 square cells.
Carousel 1 cm square: Optional measurement of carousel insert with up to 7 square cells.
