The measurement of a calibration cell in the Limas11 and Uras26 analyzer modules
means:
Determining what calibration cell "deflection" is equivalent to the test gas
calibration reading. This "deflection" is stored as the calibration cell "set value".
We recommend measuring the calibration cells once a year.
We recommend measuring the calibration cells
• after end-point calibration of a sample component with test gas or
• after any change in measurement range limits (see "Limas11, Uras26: Notes for
Changing Measurement Range Limits" section, page 7-A-3) or
• after a relinearization (see "Limas11, Uras26: Relinearization" section, page 9-8).
Prior to measuring the calibration cells, the zero and end points of the applicable
sample components must be calibrated with test gases.
During calibration cell measurement the zero gas supply must be turned on.
