Internal Clock Indicated real time and date; 0.007% time base accuracy
Programmable Delay Programmable sampler start time/date
Manual Sample Initiates a sample collection independent of program process
Data Logging
Records program start time and date, stores up to 400 sample collection
times/dates, all program entries, operational status including number of minutes or
pulses to next sample, bottle number, number of samples collected, number
remaining, sample identification number.
Automatic Shutdown
Composite Mode: After preset number of samples have been delivered to
composite container, from 1 to 9999 samples, or upon full container.
