Portable Or Refrigerated Sampler - Teledyne 3700 Installation And Operation Manual

3.9.3 Portable or
Refrigerated Sampler
• The second display sets the number of bottles (1, 4, 12,
or 24) for portable configurations. The second display
appears only when you specify a Portable sampler in the
first display.
• The third display sets the number of bottles (1, 2, 4, 8,
12, 24) for Refrigerated Samplers.
• The fourth display sets the bottle volume.
Because the 3700 Series Standard and Compact Samplers use
the same control box, you specify the type of unit as "POR-
TABLE." You should not specify "REFRIG" unless you move the
control box to a refrigerated base. (Display #220)
Bottle options – If you specify "PORTABLE" in the previous
display, you will be able to specify a 1-, 4-, 12-, or 24-bottle config-
uration. The sampler comes configured for the number of bottles
ordered with the sampler. Change this configuration setting
whenever you change bottle sets. (Display #221) The 2- and
8-bottle options are available only if you have a refrigerated base.
(See the instruction manual for the 3700FR sampler for more
information.)
If you have a 3700 Compact, 1-, 12-, and 24 bottles are the only
valid choices, as the 4-bottle option is not available.
SAMPLE CONTINUOUSLY?
[YES, NO]
The 3700 Standard can be programmed for continuous sampling,
which means that they will sample into successive sets of bottles
until the last set of bottles has been sampled into, and then
return to the first set of bottles and continue sampling indefi-
nitely into successive sets. Continuous sampling is available for
all multiple bottle configurations.
Note
The sampler will deposit samples indefinitely, even though the
bottles have been filled to capacity. To avoid overfilling the bot-
tles, replace them at regular time intervals or as soon as they
are filled.
Bottle Volume – The sampler wil l a ccept bottle volumes
between 100 ml and 30,000 ml. It uses the bottle volume to cal-
c u l a t e t h e r a n g e o f a c c e p t a b l e s a m p l e v o l u m e s i n t h e
sample-volume input display and to check for probable overfill
when running a sampling routine.
Table 3-2 lists Teledyne Isco's standard bottle sizes for composite
samplers. When using the standard bottles, enter the bottle
volume setting listed in the third column of the table. We have
adjusted the recommended bottle sizes downward. Using the
lower, adjusted volume helps prevent overfilling. If you are using
