5.3 Set Up
746 VA Trace Analyzer / 747 VA Stand
5-26
Parameter Range; Default value / Meaning
V.meas max 1...999 mL; 80 mL
Maximum fill volume
Setting of the maximum fill volume for the measuring vessel of the 747
VA Stand. It must be ensured here that the measuring vessel is not
overfilled. In dispensing operations which would lead to this volume
being exceeded, an error message appears.
The following settings are recommended:
Measuring vessel V.meas max Measuring vessel V.meas max
6.1415.210 80 mL 6.1450.210 80 mL
6.1415.150 70 mL 6.1456.210 80 mL
6.1418.220 70 mL 6.1457.210 80 mL
V.rinse 1...999 mL; 8 mL
Rinse volume
Setting of the rinse volume for manual rinsing of the measuring vessel
triggered by the softkey
.
This parameter is displayed only if two rinsing Dosinos are attached to
the 746 VA Trace Analyzer.
V.standby 1...999 mL; 0 mL
Standby volume
Setting of the volume of rinsing solution which is filled into the meas-
uring vessel after manual rinsing triggered by the softkey
meas.v.> . This volume can be used as conditioning solution for the
electrodes.
This parameter is displayed only if two rinsing Dosinos are attached to
the 746 VA Trace Analyzer.
U.standby display only
Standby voltage at electrodes
Display of the polarization voltage set to the electrodes at the end of
the determination (
U.standby is set with the ØMEAS command).
Rinse unit pos. exch., rinse; exch.
Position of the rinsing Dosinos
Display of the current position of the two rinsing Dosinos used for
rinsing the measuring vessel and siphoning off solution:
exch. Exchange position (dosing unit can be changed)
rinse Rinse position
To fill or empty the containers or to remove the dosing units from the
Dosinos, the Dosinos must be in the
exch. position. If the Dosinos
are in the rinse position, they have to be switched to the exchange
position by pressing .
This parameter is displayed only if two rinsing Dosinos are attached to
the 746 VA Trace Analyzer.
