iEFM-Specific Menus
The iEFM tabs include menus for calibrating the sensor and the gas element on
the iEFM device. Figure 3-19 below shows the menu for calibrating the sensor,
and Figure 3-20 on the following page shows the gas element calibration menu.
This section also discusses the iEFM sensor data window.
iEFM Sensor Calibration
The iEFM operation requires a number of parameters for valid measurements that
are entered using the sensor calibration menu shown in Figure 3-19 below, which
is accessed by selecting the Sensor Cal tab. The values for Temp cal intercept
and Temp cal slope are entered at the factory and are matched to the external
sensor that is supplied with the iEFM. The other parameters are dependant on
the process equipment to which the iEFM is attached.
