P 700 IQ
4. Measuring / Operation
4.1 Measuring operation
4.1.1 Determination of measured values
The P 700 IQ determines the measured values with a chemical analyz-
ing procedure. Each measurement takes place in several steps.
1 Draw sample and rinse the measuring circle with sample
2 Measure the absorbance of the sample without reagent (blank
value)
3 Add the reagent
4 Leave to react for the reaction time
5 Measure the absorbance of the sample with reagent
The measured values are determined at intervals specified in the set-
tings (see section 4.1.4,  51).
If the intervals overlap with the specified start times and intervals of
other functions (Autom.cleaning or Autom.calibration), the functions
are carried out according to their priority (see section 4.1.4,  51).
4.1.2 Starting the measuring operation
Prior to starting the measuring operation, you always have to check the
readiness for operation of the individual components of the P 700 IQ.
The analyzer does not automatically start measuring when being con-
nected to the IQ S
ENSOR N ET .
Start the measuring operation manually in the calibration and service
menu.
1 Using <>, select the P 700 IQ in the measured value display.
2 Using <C>, switch to the calibration and service menu.
The maintenance condition is activated.
3 Confirm the maintenance condition with <OK>.
The calibration and service menu is displayed.
