Appendix D Display Index
D-3
This display follows Display #20 when you select “YES” to modify the nonuniform time-interval sequence. Enter the
number of sample events to occur at nonuniform time intervals. MAX varies according to the bottle size entered in
Display #223
Display 25
TAKE --- SAMPLES
(1 -
MAX
)
This display follows Display #25. Enter the nonuniform clock times and dates for each sample event.
Display 26
TAKE SAMPLES AT
1. HH:MM DD-MMM
Enter the number of samples to be taken at each interval. The total quantity you enter will be 1 fewer than the total
number of samples, because the first sample, taken at the start time, counts as 1. For example, if you want to take 19
samples (the first 6 at 20-minute intervals, the next 9 at 30-minute intervals, and the remaining 3 at 45-minute inter-
vals), first enter a quantity of 6 at 20 minutes, 9 at 30 minutes, and 3 at 45 minutes. Figure D-1 shows a time line for
the sampling routine.

QUANTITY AT INTERVAL
1. -- AT --- MINUTES
This display appears for samplers configured for 2, 8, and 24 bottles (Display #s 221 or 222) with the 3700 Portable or
24 for the 3700 Compact (Display #22X). It does not appear for samplers configured for a single bottle. In the basic
programming mode, it follows Display #36. In the extended programming mode, it follows one of the four sample-inter-
val entry displays (Display #s 21, 22, 26, 27). Enter the number of bottles to receive a sample volume at each sample
event.
Display 30
-- BOTTLES PER
SAMPLE EVENT (1 - MAX
)
In the basic programming mode, this display appears when you have selected “SAMPLES PER BOTTLE” in Display
#36. In the extended programming mode, it appears when the sampler is configured for 2, 8, or 24 bottles and there is
only one bottle set. Enter the number of samples you want deposited in each bottle.
Display 31
-- SAMPLES PER
BOTTLE (1 -
MAX
)
Select “YES” if you want the routine to perform bottles-per-sample or samples-per-bottle multiplexing. Select “NO” if
you want the routine to perform sequential sampling.
Display 35
MULTIPLEX SAMPLES?
[YES, NO]
This display appears when you have selected “YES” in Display #35. Select “BOTTLES PER SAMPLE” if you want the
sampler to perform bottles-per-sample multiplexing. Select “SAMPLES PER BOTTLE” if you want the sampler to per-
form samples-per-bottle multiplexing.
Display 36 [BOTTLES PER SAMPLE,
SAMPLES PER BOTTLE]
This display appears only in the extended programming mode when you have set the number of bottles per sample
event to “1” in Display #30. Select “TIME” if you want the bottles to be switched after a specified period of time. Select
“SAMPLES” if you want the bottles to be switched after a specified number of samples have been placed in a bottle.
We recommend using “SAMPLES” for time-paced sampling routines.
Display 40
CHANGE BOTTLES BASED
ON [TIME, SAMPLES]
This display appears when the number of bottles per sample event is set to a number greater than one and less than
half the number of bottles in the tub. Select “TIME” to switch bottle sets after a specified period of time. Select “SAM-
PLES/BTL” to switch bottle sets after a specified number of samples have been placed in a set of bottles. Teledyne
Isco recommends using “SAMPLES/BTL” for time-paced sampling routines.
