3.5.3 Configure Sequence
3.6 Programming
Procedure
3-12
The program sequence and the configure sequence are interde-
pendent. The selections you make in the configure sequence
determine what settings will be available to you in the program
sequence. When you select the extended programming mode, the
program sequence is modified to accommodate the extended fea-
tures by adding one or more input displays.
The extended programming mode not only extends the number of
features available in the program sequence, it extends the
number of configure options. When you select extended pro-
gramming, for example, you can enable the Sampling Stop and
Resumes and/or Nonuniform Times features so you can use them
in the extended program sequence.
When you select the basic programming mode, these configure
options are not available to you. As in the programming
sequence, less frequently used options have been separated to
simplify the configuration process.
Most configure options are available in both programming
modes. Table 3-1 summarizes the configure sequence options;
each option is marked as available in both modes or available
only in the extended mode. A detailed discussion of each configu-
ration option is found in the sections beginning with Set Clock
through Exit Configuration.
It is usually not necessary to change the configure option settings
unless the sampling application changes significantly. The
sampler is always programmed and configured: the sampler's
internal battery maintains program and configure settings. In
fact, the sampler is shipped with factory program and configure
settings. It is configured for the basic program mode and for the
bottle configuration and suction line ordered with the sampler.
The procedure used to program the sampler follows the steps
listed below.
Note
Because the configuration settings determine portions of the
program sequence and affect the accuracy of the sample,
check the configuration settings before programming.
1. Determine the equipment you will be using with the sam-
pler. You will need to know the capacity of the bottles and
the inside diameter, type (vinyl or TEFLON), and length of
the suction line. You will need this information to verify
and revise the configuration settings in step 2.
If you will be using the sampler for composite sampling,
you may need to convert the sampler. The section Conver-
sion for Composite Sampling in Section 4.2 provides infor-
mation on converting the 3700 Standard for composite
sampling. Example Time-Paced Composite Sampling dem-
onstrates the configuration changes you must make.
2. Check the configuration settings. From standby, access the
interactive state. Select the configure sequence. Check the
