Temperature Compensation

Temperature Compensation...The temperature compensation feature is used to correct for peak drifting due to changes

in temperature experienced by the detector. When temperature correction is enabled and the proper values have been

entered into the correction parameters, the ICS-PCI card will correct for the peak drift as the detector temperature

changes.

Parameters...This dialog allows entering the temperature correction values if they are known. If a temperature correction

calibration has been performed, the values will be displayed in this dialog box.

Setup...The interval time, the time between measurements, can be set from 5 to 60 minutes. The total time of the

temperature compensation calibration can be set from 4 to 24 hours.

Calibrate...Starts the temperature compensation calibration measurements. After the measurement has been completed,

the software will store the determined parameters and automatically enable the temperature compensation.
