6712 Sampler
2-18
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 a pressurized line.
2.14.1 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 Example 2-2.
4. Reconnect the pump tube to the bulkhead
fitting.
