Step
Action
Data entered/ value displayed
1
Execute EView2, detect device and open “DEVICE SETTINGS” window.
2
Press the “Oscilloscope” button in the window and read the oscilloscope diagram of the device
3
The top-left of the window displays distance, peak amplitude in volts and gain.
21.000 mm (0.83 inch) 1500 mV Gain 2
4
The configured level threshold is listed under peak amplitude in mV.
Click on the “Modify” box to activate the “Threshold” field.
5
Click on the “Threshold” field and enter a new value. Press enter and press and select “save”.
1100 mV
6
Refresh the oscilloscope diagram (F4 key)
7
If the value is still too low, try to reduce threshold again in small steps.
If this does not resolve the problem, contact the NIVELCO Service Centre.
Note:
the threshold drops every 2 m (6.5 ft).
Solid application notes:
Most solid applications except powder or flakes with high dielectric constants
r
, such as coal powder, are measured with Gain set to 3. If it is difficult to measure level
at a certain point with the gauge using Gain from 0 to 2, then an internal tank structure (protruding parts, etc.) is most likely within the electromagnetic pulse field area:
the gauge will detect the largest signal and assume this is the medium level.
