Function Info
Power failure Decide how the sampler should react when it is energized after a power failure.
Resume program:
• Time and flow-paced
The program calculates the omitted samples and enters them in the logbook
as failed. When the program is restarted, it continues where it was
interrupted.
• Flow-paced
No samples are entered in the logbook during the power failure. When the
program is restarted, it continues where it was interrupted.
Sample volume Time paced CTCV
A constant sampling volume is taken at steady intervals.
Flow paced VTCV
A constant sampling volume is taken at variable intervals.
Time/flow paced CTVV
A variable sampling volume is taken at steady intervals.
Sampling interval Set the sampling interval.
The pulses are scaled at the flowmeter. By multiplying the pulses at the sampling
interval, the shortest sampling interval at the maximum pulse frequency can be
set. Example: With a maximum flow rate of 600 m
3 (21188ft 3 )/h, the pulse
frequency at 5 m 3 (176.57 ft 3 ) is 120 pulses/h or 2 pulses/min. With a sampling
interval of 20 m 3 (706 ft 3 ), a sample is taken after 4 pulses = 2 minutes.
Bottle synchronization The bottle synchronization setting is possible with all types of program. Bottle
synchronization is only possible with a bottle change after a specific time and not
with a bottle change after a number of samples.
Specific bottles can be assigned specific filling times with the bottle
synchronization function. For example, bottle 1 is to be filled from midnight to 2
a.m., bottle 2 from 2 a.m. to 4 a.m. etc.
Stop condition Use this function to enter the end of the program and to specify continuous
operation.
End of program: the program stops automatically once it has gone through all
the bottles once.
Continuous operation: the program runs in a continuous loop. The bottles must
be emptied regularly.
