2) Using the MT-TDL Software Suite
• From the main screen, select the ppm trend tab and observe the signal
and the displayed NSL value, while adjusting the process purge flow
rate.
• Adjust the process purge flowrate to achieve an NSL of 40 or lower,
while maintaining a good transmission value (> 70%).
• This will achieve the optimal process purge flowrate and best signal
quality.
Always start purging at maximum flow before starting the process.
Purging must always be switched on in order
to avoid dust deposition onto the optical surfaces.
PATH: H\Cal\Calibrate Sensor
Calibration for a GPro 500 is performed as a one-point or process calibration.
The following menus can be called up:
Unit:
One of several units can be chosen. The units are displayed
during the calibration.
Method:
Select the desired calibration procedure, 1-point or process
calibration.
Options:
If the 1-point method has been chosen the calibration pressure,
temperature and the path length for the sensor signal during the
calibration can be edited.
The changes are valid until the calibration mode has been exited. After, the
values defined in the configuration menu are valid again.
