A.1 Specifications
Ranges: Two user selectable ranges can be set
between 0-10 ppm and 0-9,999 ppm
oxygen. Default ranges are 0-100 ppm and
0-1,000 ppm oxygen, and a 0-25 % (nomi-
nal) Air Calibration Range.
Signal Output: Voltage: 0–10 V dc, negative ground
Current: 4-20 mA, negative ground
Range ID: 0-10 V dc.
Display: Light emitting diode (LED) display.
Alarms: One high alarm relay, adjustable; one low
alarm relay, adjustable; one sensor failure
relay. (All are failsafe.)
System Operating Temp: 0-50 °C
Accuracy: ±2 % of full scale at constant temperature
±5 % of full scale through operating tem-
perature range (At 100 ppm and higher user
defined ranges) once temperature equilib-
rium is reached.
±1 ppm for 10 ppm range under above
conditions.
Response Time: 90 % in less than 65 seconds at 25 °C
(68 °F).
System Power Requirement: AC (100 to 240 V ac, 47/440 Hz), or
DC (10-36 V dc); user specified.
