Troubleshooting procedures
5.5.3 Probe End Pulse offset (only relevant for PEP)
An offset of the probe end pulse is normal if there is product in the vessel. However, it can also
be caused by mis-configured probe length. Ensure that correct probe length is configured by
emptying the tank and reading the probe end pulse or measuring the probe. Also ensure that
PEP in “Probe End Projection (Rosemount 5300 Series solids measurement)” on page 48 has
been followed.

5.5.4 Analog output settings
Review the analog output settings. The primary variable determines the output, and is often set
to level. The definition is:
Level = tank height (reference gauge height) - measured distance
Consequently, the zero level point is at tank height (reference gauge height), below the
transmitter's flange. The LRV (4 mA setpoint) and URV (20 mA setpoint) should be set with this
zero point as reference.
Probe length and tank height (reference gauge height) do not need to match.
