Footnote:
1. Accuracy of reading at default Alarm 1 concentration (typically 10% FS or defined minimum alarm level setting, whichever is greater) when operated at default full scale.
Note:
• Sensor drift between LDL and negative drift fault limits (typcially > negative zero variation) appear as 0 on the display and outputs of the device. • Long-term drift: XNXXSC1SS <5%/year, XNXXSO1SS <4%/year, XNXXSH1SS and XNXXSH2SS <2%/month. 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.
• Operating the XNX EC sensor at extended temperature ranges for a prolonged time period exceeding 12 hours may cause deterioration in sensor performance and shorten sensor
life. Extended temperature ranges for XNX EC sensor cartridges are -40°C to -20°C.
• 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.
• Response times may increase at lower temperatures. • Contact Honeywell Analytics for any additional data or details.
