Footnotes:
1. XNXXSC1FM accuracy over temperature <±10% of reading 20°C/68°F to 55°C/131°F, <±20% of reading 20°C/68°F to -10°C/14°F, <±30% of reading -10°C/14F to -20°C/-4°F.
Recalibration is recommended if the temperature of the local environment has varied by more than -30°C.
Notes:
• Performance gures are measured by test units calibrated at 50% of full scale, at ambient conditions of 20°C, 50% RH, with the EC weatherproof cover attached
• IP rating of FM Cartridges is IP63.
• Barometric pressure effects on the O
2
sensor: The output from the O
2
sensor has pressure effects of <0.1% change of output per % change in pressure. When the barometric
pressure changes by ±20% the output from the O
2
sensor changes <±0.4%Vol. However, the oxygen sensor shows transient behavior when subjected to a rapid change in
ambient pressure due to either weather or altitude. For example, a 10KPa instantaneous positive pressure step change may cause an overscale alarm condition for a period
of about 12 seconds.
• Operating the EC sensor at extended temperature ranges for a prolonged time period exceeding 12 hours my cause deterioration in the sensor performance and shorten
sensor life. Extended temperature range for XNX EC sensors is -40°C ot -20°C.
• Response times may increase at lower temperatures.
• FM performance verification is limited to the requirements of the standards identified in Table 6.3 for each cartridge.
