4.12 Calibrate Volume
The sampler delivers accurate sample volumes without cali-
bration. If you find that sample volumes vary significantly from
the programmed values, first check the suction line for proper
installation. Be sure it slopes continuously downhill to the liquid
source and drains completely after each sampling cycle. Then,
compare the actual length of the suction line to the suction line
length settings in the program to see that they match. Also check
the pump tube for excessive wear and replace it if necessary.
You may want to calibrate when:
• A new pump tube is installed. Run the pump for five
minutes before calibrating.
• The sample source is above the sampler.
• Sampling from pressurized lines (15 PSI Maximum).
4.12.1 Calibration Tips
• For the best results, calibrate the sampler after it’s
installed on site.
• Use a graduated cylinder for volume measurement.
• The sampler clears the previous calibration setting
when you reinitialize the sampler.
• You cannot calibrate while the sampler is running a
program.
• When the sampler delivers the sample, it runs through a
complete sampling cycle, using the current settings for
volume line rinses and retries. If it is a two part
program, the sampler uses the volume setting for part
A.
To calibrate:
1. Disconnect the pump tube from the bulkhead fitting.
2. Place the end of the tube over a collection container.
3. Follow the steps in Calibrating Sample Volumes in the
margin.
4. Reconnect the pump tube to the bulkhead fitting.
