Basic programming setup
8-A.
Enter the desired volume of each sample using the numeric keypad. Press
ACCEPT
to continue to Intake Rinses.
Step 9 - Intake rinses
9-A.
Enter number of rinses using the numeric keypad.
Up to three intake rinses are enabled per sample cycle. After the sample cycle’s initial
purge has been completed, the sample liquid is drawn in until it reaches the liquid sensor.
The pump stops and purges the line before any liquid enters the bottle. This is repeated
up to three times before the actual sample is taken and the line purged for the final time
during that cycle.
Intake rinse can prevent cross contamination of samples. When the line is purged at the
end of each sample cycle, a few droplets of sample liquid may cling to the inside walls of
the tubing and the droplets are drawn in with the following sample. Intake rinses will
condition the intake line with a source liquid that minimizes contamination from the
previous sample.
9-B.
Press
ACCEPT
to continue to Sample Retries.
Step 10 - Sample retries
Note: Excessive intake tube line lengths combined with multiple Intake Rinses and Sample Retries
can increase the pump tube and drive train wear. Locate the sampler as close to the sample liquid
source as possible to minimize wear and maintenance requirements.
10-A.
Enter the number of Sample Retries using the numeric keypad.
Up to three sample retries are enabled per sample cycle. After the initial purge is
completed, the sample liquid is drawn until it reaches the liquid sensor. If the sample
liquid does not reach the sensor within a reasonable time (determined using the tubing
length), the sample attempt is aborted, a purge is initiated and the first of up to three
sample retries is attempted.
