3700 Portable Samplers
Section 2 Setup Procedures
2-7
2.7.1 Connection to a Flow
Meter
Section 4.3 discusses connecting the sampler to Teledyne Isco
and non-Isco Flow meters. If there is not a connect cable attached
to the flow meter connector on the side of the sampler, be sure
that the protective cap is tightly screwed in place to maintain the
water-tightness of the unit.
2.7.2 Saving Program
Settings
You can program the sampler for automatic operation. Because
the lithium battery maintains the program settings, you can
easily program the sampler — even when it is turned off — in the
office or the lab, take it into the field, and place it into operation.
To start the sampling program, press the start sampling key,
located on the control panel.
2.8 Recovering the
Sampler
When you recover the sampler, keep it level to prevent spilling
the collected samples. If you must return the entire sampler to
the laboratory or office, disconnect the cable from the flow meter,
if used. You can turn off the sampler, but this is not necessary.
Separate the base section from the center section, as described
previously, and install caps on the bottles. The sampler is now
ready to transport.
2.8.1 Exchanging Sampler
Tubs
If you do not need to return the entire 3700 Standard sampler to
the lab, you can exchange the full base section for an empty one
by separating the base from the center section and installing an
empty tub. After the full base has been removed, place caps on
the bottles. Using the base section as a carrying case is conve-
nient, prevents undue warming of cooled samples, and helps to
prevent mix ups in bottle order. An optional cover, with carrying
handles, for the base section is available to aid in transportation.
Attach the cover to the base in the same manner as the center
section. It is good practice to attach an adhesive label detailing
the location, time, date, etc., of sampling to avoid confusion.
When exchanging bottle tubs, it is also good practice to check the
charge of the sampler’s battery. If the sampler’s battery is ques-
tionable, exchange it with a freshly charged battery.
With the 3700 Compact, there is no need to change bases. Slide
the sleeve out to remove the bottles for transporting off-site.
Place caps on the bottles and you may want to attach an adhesive
label with relevant details on the sleeve as noted above.
2.8.2 Restarting After you have installed the base section with empty bottles in
the standard, or replaced the full bottles in the sleeve with empty
ones in the compact, start the sampler again by pressing the
start sampling key. You may need to reprogram the start time, if
one has been entered.
2.9 Sampler Locking
To prevent tampering with the controls and sample bottles, the
sampler can be locked with the locking cable accessory package.
For standard-size 3700 Samplers, use P/N 68-6700-134; use P/N
68-6700-111 for 3700 Compact Sampler. The sampler is secured
with three stainless steel cables and a padlock. To secure the
sampler, place the hook on the end of the cable through the hole
on the latch, as shown in Figure 2-6. Repeat this with the other
