Description
The volume of each sample in mL (1 gal = 3785.4 mL). If bottles/sample mode is
used, each bottle receives a full sample volume (10–10,000 mL). Make sure that the
sample volume does not exceed the bottle volume. Sample volumes are rounded to
the nearest 10 mL.
The number of intake tube rinses before a sample is collected (0–3).
The number of sampling tries after a sampling failure occurs (0–3).
The name for the sampling location (up to 12 characters). The site ID is used as the

Specify whether the sample volumes vary (flow based). If yes, refer to
volume on page 19. If no, refer to
Description
Select the flow units to use.
Enter the flow rate that agrees with 4 mA input.

Specify the average flow rate for the site (1–999,999). The units are specified by
the units selected above.
Specify the total volume to be collected during the sample program
(10–10,000 ml).
