tered under sample sequence in the 766 IC Sample Processor.
Procedure at program start
1. Create new queue in the program «IC Metrodata» and start it.
2. Enter parameter
number of samples
for 766 IC Sample Processor.
3. Start 766 IC Sample Processor with .
4.6.4 Method "SP Seg"
Application
Processing a queue with the PC program «IC Metrodata» with the 766
IC Sample Processor as "Master", additional insertion of a defined air
bubble between the samples.
Interconnection
