Current
outputs:
SINGLE STREAM OR MULTISTREAM
As standard, two isolated current outputs 0 to 1, 0 to 10, 0 to 20,
or 4 to 20mA, software selectable. Range independently selectable
over the full range of the monitor. Maximum voltage load is 15V.

SINGLE STREAM
Two concentration relay outputs. Can be configured as high or low
concentration. 'Out-of-sample' alarm, remote calibration-mode indication
and remote monitor 'out-of-service' alarm.
MULTISTREAM
Maximum of six (one per stream) relay outputs. Can be configured
as high or low concentration, or 'out-of-sample' alarms. Remote
calibration-mode indication. Remote monitor 'out-of-service' alarm.
Concentration
alarm adjustment:
Programmable over range of monitor.
Calibration:
Frequency and time of day programmable, fully automatic, plus manual
initiation on demand.
