iEFM-Specific Menus
The iEFM tabs include menus for calibrating the sensor and the gas element on
the i EFM device. Figure 21 below shows the menu for calibrating the sensor,
and Figure 22 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 21 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.
