Save icon
Depending on setup under Instrument Setup > Data Log Setup > Auto Store: On or Off the
stored data is called up with the Save symbol or a manual save is performed.
Abs % Trans Switches from % transmittance to absorbance in reading mode.
Send Data icon To send data to a printer, computer or USB memory stick (USB A) or network.
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.
Note: If undiluted samples are used, set the dilution factor off.
Chemical Form Some of the stored tests/methods allow to select the chemical form and the measuring range.
Reagent Blank: Off/On
The function "Reagent Blank" is available for several barcode tests. 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) * Abs] - (reagent blank)
