each pumping cycle. Then, check the suction-line entries in the
configure sequence to see that they are accurate. The calibration
procedure is intended to be for "fine tuning" only.
After you enter the sample volume actually delivered, as shown
in Step 6, all subsequent sample volumes delivered will be
adjusted to correct for the difference between the expected
sample volume and the actual volume entered. Clear the
adjustment by changing a suction line entry in the Suction Line
configure option or by reinitialization of the sampler.
Because the sample volume can be calibrated to ± 10 ml, use a
graduated cylinder to facilitate measurement. Teledyne Isco
offers a graduated cylinder and spare bottles as accessories from
the factory. Refer to the Appendix B Accessories List for details.
The calibration pump cycle will include rinse cycles and retries, if
the sampler is configured to perform them. This ensures that the
calibration procedure includes the pump cycle used while
running the sampling program.
