3. Press SET Select the SET menu.

Scroll through the SET menu to the CALIBRATE attribute.

5. Press EDIT Set the CALIBRATE attribute value to ON to enable Dynamic

Span.

6. Press EXIT Causes the M200A to return to SAMPLE mode.

NOTE

If you try a Dynamic span calibration using the NO

permeation tube

as a calibration gas source, the NO channel concentration will be zero

due to the lack of NO in the NO

permeation tube. An error message

will be displayed, CANNOT CALIBRATE. We recommend a calibrated

NO tank for complete calibration. Also see the CAL-ON-NO2 option.

With dynamic calibration turned on, the instrument will re-set the slope and offset values for the

NO and NO

channel each day. This continual re-adjustment of calibration parameters can often

mask subtle fault conditions in the analyzer. It is recommended that if Dynamic Cal is enabled,

the TEST functions, and SLOPE and OFFSET values in the M200A are checked frequently to

assure high quality and accurate data from the instrument.
