With dynamic calibration turned on, the instrument will re-set the slope and offset values for the NO and NOx 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, SLOPE and OFFSET values in the M200AU should be checked frequently to assure high quality and accurate data from the instrument.

7.5 Use of Zero/Span Valves with Remote Contact Closure

The Zero/Span valve option can be operated using Remote Contact Closures provided on the rear panel. See Figure 2-2 for connector location and pinout. When the contacts are closed, the analyzer will switch to zero or span mode. The contacts must remain closed for at least 1 second, and will remain in zero or span mode as long as the contacts are closed. To calibrate the instrument at the end of the Zero/Span valve cycle (DYNAMIC CAL), the CAL_ZERO and CAL_SPAN variables in the VARS menu must be set to ON.

The CPU monitors these two contact closures and will switch the Analyzer into zero or span mode when the contacts are closed for at least 1 second.

In order to do another remote check, both contact closures should be held open for at least 1 second, then may be set again. Table 7-8 shows what type of check is performed based on the settings of the two contact closures.
