4.3 Span Calibration
4.3.1 Introduction.
The Multi Gas Monitor – INNOVA 1316A-3 is designed to be span-stable.
Frequent span calibration is not required to maintain accurate gas concentration
measurements. The Multi Gas Monitor may need to be routinely span calibrated
with suitable mixtures of calibration gases. Span calibration is recommended at
the following intervals:
¨
The VM0102A module measuring Ethanol, CO, and CO
2
: Once every 12
months.
¨ NO sensor VM0201A: After replacement of a NO sensor, and once every
month during normal operation.
¨ O
2
Sensor VM0200A: Span calibration is performed during every Zero/O
2
Span Calibration execution.
¨ When any span calibration has failed.
4.3.2 Checking and Changing the Particle Filters
It is recommended to change the inlet filter DS2306 before
performing any calibration.
