configuration settings, revising any settings as needed;
select basic or extended programming mode. Return to the
standby state.
Example Checking the Configure Option Settings shows
you how to check and revise the configuration settings in
the configure sequence. (We recommend you review the
upcoming sections Keypad Description and Displays before
you work through the programming examples. These sec-
tions discuss the functions of the individual keys and how
to use the keys when programming the sampler.)
3. Program the sampler. Again, from standby, access the
interactive state. Select the program sequence. Enter the
program settings for your routine. The sampler will
prompt you through the programming process. When the
process is completed, the sampler will automatically return
to standby.
For a more detailed discussion of the programming proce-
dure, see the section Basic Programming Procedure. The
examples given demonstrate several types of sampling pro-
grams in the basic mode. Examples of extended mode sam-
pling programs are also shown.
4. If desired, connect the sampler to a flow meter or other
interfacing equipment. Start the sampler.
5. As the routine is executed, the displays will report the
sampler's progress. The programming examples in this
manual conclude with the run-state displays you should
see for each sampling routine. When the routine is done,
the sampler will return to standby.
6. Retrieve the filled sample bottles. If you wish, use the Dis-
play Status procedure discussed in detail later in this sec-
tion to examine the sampler's log of sampling results.
7. If you need to reprogram the sampler, follow this procedure
from the beginning. If the sampler's current program is
correct, restart the sampling routine.
Configuring and programming the sampler is as simple as
responding to displays on the LCD with the keypad. The sampler
will prompt you through many of the entries by presenting a
question or a choice on the display. You must respond with the
keypad. The LCD and the keypad are located on the 3700
Sampler control panel.
The following section summarizes each key's function. The
section Displays discusses LCD displays and ways you can use
the keypad to interact with the sampler.
Keys are grouped together on the control panel to assist you in
identifying related functions. Control keys manually control the
sampler; numeric keys are used to enter program values; pro-
gramming keys are used to monitor the sampler's status and
direct programming activities. Key names are represented by
small capital letters in this manual.
