Caution
Gas concentrations below the full scale of the measuring
range will not be reported until after the sample time
duration has completed. For measured values above the
measuring range, an alarm will be issued immediately.
Notes:
“Sample time” in the table above represents the time required to:
• Detect < full-scale gas concentration
• Calculate and display concentration value
• Update the 4-20 mA signal
• Produce a RS-422 data packet (optional)
When concentration is > full-scale, response time is shortened in
proportion to the concentration.
Example:
Ammonia Full-scale = 75 ppm. Response time = 15 sec
Concentration 20 ppm 75 ppm 150 ppm 300 ppm
Response Time 15 seconds 15 seconds 7.5 seconds 3.8 seconds
