Switchover to normal operation (concentration measurement)
CLOC
Reads out stored measured values;
CDAT [anz]
[anz] = number of the measured values to be output
CMES [MMM] Measurement and transmission of the concentration value with date/time;
[MMM] = method number (e.g. 086 for method 14729)
CEXT [LLL] Measurement and transmission of the absorbance value for the wavelength;
[LLL] = wavelength
CBLA [MMM] Measurement and transmission of the sample blank value;
[MMM] = method number
CCLB [MMM] Erase measured sample blank values; [MMM] = method number
The error message, Invalid command, appears if
commands are unknown or cannot be carried
out (e. g. if optional parameters do not agree with
the cell coding). Optional parameters [MMM] and
[LLL] need only be input for uncoded cells.
