Operation
Using the temperature controllers
The FTIR Heated Valve Drawer features a temperature controller for each heater. The temperature
controller can be used to set the target temperature and ramp rate, monitor current temperature, set
an alarm for overheating, and more.
Device Controls
The temperature controller can be operated using displays and controls on the device.
For additional details on using the temperature controller, see the manufacturer’s user guide at

Operating Limits
Do not raise the set point above 191 °C. The temperature controller is programmed to prevent raising
the set point above this temperature to protect the system.
NOTICE
Do not raise the set point beyond the operating limits of the gas cell you are using. Heating the gas
cell beyond the cell limits can damage the cell windows and gaskets, causing leaks and degrading
the quality of the measurement.
See the user guide for your gas cell for more information.
Factory Presets
To protect the gas cell and instrument, the following parameters have been preset:
l
Set point: The temperature controllers have been configured with a set point of 180 °C. You can
change the set point as needed.
l
Ramp rate: We configure the system with a ramp rate of 1 °C per minute (1.8 °F per minute) until
the set point is reached to protect the gas cell and instrument.
