10.4 Treatment of measurement errors
The tables below give typical examples of application-related meas-
urement errors.
The images in column "Error description" show the actual level as a
dashed line and the output level as a solid line.
10 Diagnostics and servicing
Rectification
Make sure that there is no further filling
Check level in the vessel
Check terminal voltage, increase operat-
ing voltage
Rectification
Check connections
Exchanging the electronics
Send instrument for repair
Clean the antenna
Use a more suitable antenna/sensor
Remove possible false echoes
Optimize sensor position and orientation
Carry out reset and repeat setup
