If NO is selected:
a. Select Samples per Bottle or Bottles per Sample.
Example 1: Samples Per Bottle
• Bottles— 8
• Sample Collection; Time-Proportional; Sampling Interval—30 min.
• Sample Distribution; Deliver Each Sample to All Bottles?— No
Samples Per Bottle— Yes
Number of Samples Per Bottle— 3
• Sample Volume—100 mL
Every 30 minutes a sample is initiated. A 100 mL sample is drawn into
bottle #1, 30 minutes later a second sample is drawn into bottle #1, 30
minutes later a third sample is drawn into bottles #1. Thirty minutes later
the distributor arm advances to bottle #2 and a 100 mL sample is drawn
into bottle #2. The sequence continues until all bottles are filled. Each
bottle receives three samples before the distributor moves to the next
bottle.
Example 2: Bottles Per Sample
• Bottles— 4
• Sample Collection; Timed Proportional; Sampling Interval— 30 min.
• Sample Distribution; Deliver Each Sample to All Bottles?— No
Bottles Per Sample— Yes
Number of Bottles Per Sample— 2
• Sample Volume— 1000 mL
Note: A high pressure air purge is
automatically applied to the intake
tube between each sample
intake cycle. Every 30 minutes a sample cycle is initiated. A 1000 mL sample is drawn
into the first bottle. The distributor arm immediately advances to bottle #2
and a 1000 mL sample is drawn into the second bottle. Thirty minutes
later, the distributor arm advances to bottle #3, and a 1000 mL sample is
taken. The distributor arm immediately advances to bottle #4 and a 1000
mL sample is drawn into the fourth bottle. The pattern continues each
sample cycle with each set of two bottles receiving a sample each time.
b. Press ACCEPT to continue with Liquid Sensor setup.
If YES is selected:
Each time a sample is taken it is consecutively placed in all bottles. This
allows for split samples.
