799 GPT Titrino: Titration, dosing and measuring modes

 

 

24

 

Meaning of the calculation variables 

C variables are 

• 

determined by the method (C24...C27, C4X, C5X, C6X, 

C7X, C8X) 

• 

entered as sample specific data (C00, C21...C23) 

• 

given as fixed constants in the methods (C01...C19)

Sample size, key <SMPL DATA>. 
Method specific calculation values, such as molecular mass, factors, key <C-
FMLA>. 
Sample specific calculation values, such as dilution factors, key <SMPL DATA>.
Variables for storing determination results in the silo memory. 
Means from silo calculations. 
Common variables, e.g. for titer. 
Initial measured value of the sample, last measured value for MEAS. 
End volume. 
Determination time. 
Volume drift for KFT and SET with conditioning. 
Temperature. 
Dispensed start volume. 
Asymmetry pH (pH calibration). 
Electrode slope (pH calibration). 
Volume at the point of the curve with maximum voltage. 
Volume at the point of the curve with minimum voltage. 
Fix EP for DET and MET or fix V for STAT. 
pK/HNP values for DET and MET or fix times for STAT. 
Temporary variables for calculations in TIP. 
Mean rate for STAT: Overall rate, evaluated over all points of the measuring list. 
Rates, evaluated in preset time windows for STAT. 

 

 

Sample data, key <SMPL DATA> 

• 

Sample identifications or sample specific calculation val-

ues C21...C23 

•
