Reagent changes
This procedure is applicable to each change of reagent solution. It allows the regulation of the
volumes of solutions in the bottles. The analyzer consistently checks the consumption of these
solutions, triggering an alarm when these levels get too low. This option must be selected each time
a solution is refilled or changed to reset the measurement parameters.
Note: The conditioning reagent and electrolyte consumption are approximate measurements, so a discrepancy
between measurement and actual consumption may occur. The conditioning solution consumption has been
measured for a pH of 11.2 at an ambient temperature of 25°C.
Adjust bottle volumes
This option should be used to set the default values of reagents or when bottles are being used that
are not full (see
Bottles full
1. Select the ADJUST BOTTLE VOLS. option to set the reagent volumes.
2. Enter the volumes for the conditioning solution, reactivation solution, calibration solution and
electrolyte in milliliters.
