2-28 Analyzer Variables
Bidirectional
None
Floating point
0.003
None
NDIR, PMD only; the integral "gain" for the temperature control algorithm
Used in the control algorithm. This value has been experimentally determined, and
should not under any circumstances be changed
HEATER_BIAS
HEATER_PGAIN
HEATER_SETP
Bidirectional
None
Floating point
0.2
None
NDIR, PMD only; the proportional gain for the temperature control algorithm
Used for the control algorithm. This value has been experimentally determined, and
should not under any circumstances be changed.
HEATER_BIAS
HEATER_IGAIN
HEATER_SETP
Bidirectional
None
Floating point
0-50
°C
NDIR, PMD only; the set point for the temperature control algorithm.
Used to determine the set point for the control algorithm. This value has been
experimentally determined, and should not under any circumstances be changed.

HEATER_PGAIN
HEATER_BIAS
Output
None
3-element floating point array
Same as TEMP_IS for CLD
°C
CLD only; values of TEMP_IS at manufacturing check out time
Provides historical data on how the analyzer was set up during final check out
TEMP_IS
