If you select NO, the sampler will run until it completes the
distribution sequence, at which time it stops the program and
reports PROGRAM DONE. The sampler will wait in this state
until the bottles have been emptied and the program is restarted.
If your sampler is configured for composite sampling, refer to
section 3.5.17 for instructions on continuous sampling.
At this screen you have the option to enter a sample volume
(factory default is 200 ml) or use a manually defined sample
volume based on pump counts.
If you choose ENTER SAMPLE VOLUME, the programming
displays will step through a series of screens that let you enter
the sample volume. When running a program, the sampler will
use these settings and vary the sample collection cycle to deliver
the entered sample volume at any suction head height.
To view or change the entered sample volume, use the Next or
Previous arrow to select ENTER SAMPLE VOLUME. Then, press
the Enter button to advance to the next screen (section 3.5.13).
If you choose USE DEFINED SAMPLE, the sample collection cycle
is always a fixed number of pump counts. This option can be
beneficial when sampling conditions make it difficult to detect
liquids and collect accurate sample volumes. To USE DEFINED
SAMPLE, press the Next or Previous arrow to select this option.
Then, press the Enter button.
Note
When using defined samples, be sure to DEFINE SAMPLE
using the Calibrate button. See the example "Defining the
Sample Volume" on page 3-25.
Note
Selecting USE DEFINED SAMPLE will disable bottle overflow
detection.
Time Paced Only. The sampler can vary the sample volume
according to an input from an external flow rate measurement
device, or use a fixed volume at every time interval. To use
variable sample volumes, sometimes called Constant Time
Variable Volume (CTVV) sampling, select YES. To use fixed
sample volumes, select NO.
This screen displays the defined sample volume. Use the Number
buttons to enter the sample volume. Press the Enter button to
accept the displayed value.
Time Paced Only. If you are collecting sample volumes dependent
on flow (section 3.5.12), select which type of flow rate input is
provided by the external flow measurement device (see section
2.8).
