OSCILLOSCOPE FUNCTION

) 

Click the "Echo Diagram" button in EView2 to display the 

device's echo diagram and the "Device Echo map" window will 

appear. The diagram, shows the reflection curve measured by 

the device. In addition, this window can be used to change the 

threshold level. To refresh the chart or read the data, press the 

"Refresh" button in the bottom line of the window (or the F4 

function key). 

After a successful reading, an echo graph similar to the 

attached "Echo Diagram" will be displayed. The content of the 

displayed information can be selected in the legend. The "Echo 

list" shows the location and data of the echo peaks evaluated 

by the unit, of which the selected level mark is marked 

"Selected peak."

EVEL THRESHOLD VALUE CURVE 

(“T

HRESHOLD CURVE

”) 

This function is intended for advanced users. Incorrect settings may cause the device to malfunction! 

The threshold value, or threshold line block unwanted echoes from the measurement. Echo peaks below the threshold level are not used in the evaluation. 

Adjusting the threshold may be necessary if the device selects an false echo, for example, if there is an interfering object in the path of the ultrasound burst. Before 

modifying the threshold curve, it is recommended to minimize interfering echoes by selecting the installation location of the device.
