Procedure (example where the level measured is too low compared to true level):

read off displayed peak amplitude using the oscilloscope function – F7 modify level threshold value

Step Action Data entered/ value

displayed

1 Execute PCSTAR 2. Press F2 to connect to gauge. n/a

2 Press F11 to open F11-Dynamic configuration window. n/a

3 The top of the window gives the distance, peak amplitude in volts and gain. 21000 mm;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.

n/a

5 Click on the ”Threshold” field and enter the new value. 1100 mV

6 If the approximate level is known, click on the “Distance” field and then click on the “Search” button 19000 mm

7 If the value is still too low, try reducing threshold again by small amounts.

If this does not resolve the problem, contact the NIVELCO Service Centre.

n/a

Note that the threshold drops every 2000 mm or 6.5 feet.

Solid application notes

Most dry solid applications except powder or flakes with high dielectric constants 

, such as coal powder, are measured with a Gain of 3. If it is difficult to measure

level at a certain point with the gauge using a Gain from 0 to 2, then an internal tank structure (exposed girder, etc.) is most likely to be within the electromagnetic

pulse field area: the gauge will detect the largest signal and assume this is the product level.
