INSTRUMENT DESCRIPTION
3.2.5 Set Up Stream Parameters
The analyzer is programmed to measure a singlestream system at 4 sample cycles per hour. The multistream
default is 1 cycle per stream, but you may define parameters for individual streams, such as modifying the num
ber of cycles or the alarm threshold values.

The alarm values are used to activate alarms or controllers when the sample is outside of the specified concen
tration range. A high alarm will activate when the sample concentration exceeds a preset limit. A low alarm will
activate when the sample concentration is below the preset limit.

The contacts for the alarm outputs are located at the input/output panel on the cabinet side. The system must be
in an alarm condition for at least one minute to activate the alarm contact.
