Description

 

 

Store Off/On

With the Store On setting, all measurement data are stored automatically. With the Store Off

setting, no measurement data are stored.

 

 

 

% Trans/Conc/Abs

To switch to % transmittance, concentration or absorbance readings

 

 

Send Data icon /

To send Data to a printer, computer or USB memory stick (Type A)

This functions as a stopwatch. It helps to ensure that the steps of an analysis are correctly timed

Timer icon

(e.g. reaction times, wait times, etc., can be exactly specified). When the specified time has

elapsed, an acoustic signal is emitted. The use of the timer has no influence on the measurement

 

 

program.

 

 

 

Single Reading Mode: A reading is only displayed after a measurement has been carried out

Reading Mode

(press Read; standard setting) (see section 5.4.4.1 on page 45).

Continuous Reading Mode: After the zero measurement, all readings are displayed

 

 

automatically and continuously (see section 5.4.4.2 on page 45).

 

 

 

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

Dilution Factor Off/On

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: When a dilution is in effect, the dilution icon will appear on the display.

 

 

Standard Addition

This enables the accuracy of the measurements to be checked. The (working) procedure for a

test parameter contains a detailed explanation of how to use this function.

 

Standard Adjust

The (working) procedure for a test parameter indicates whether a standard adjustment is

necessary and, if so, how to proceed.

 

 

 

Chemical Form

Some of the stored tests/methods allow to select the chemical form and the measuring range.

 

 

 

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

Reagent Blank

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 made clear by

 

the following equation: Concentration = [(Conc. factor) * Abs] – (reagent blank value).

 

 

Save as User Program

To store the selected parameters as a User Program, see section 6.1 on page 61.

 

 

Recall Data

Call up saved measurement data, wavelength scans or time courses, see section 5.3 on

page 35.

 

 

 

Instrument Setup

Basic data of the instrument, see section 5.2 on page 23.
