*AVG ERR - Average submerged temperature could not be calculated.
Possible causes for the *AVG ERR system error message include:
A. DDA tank gauge product float below lowest positioned RTD.
B. DDA tank gauge detected error from individual RTD reading.
C. Hardware malfunction detected from DDA gauge temperature measurement circuitry.
System error messages on individual RTD display example.
Some additional system error messages associated only with the individual RTD display mode are
described below. These are coded error messages that are reported directly from the DDA tank
gauge electronics and usually indicate a problem with the DDA tank gauge temperature measure-
ment circuitry or the individual RTD elements. These error codes are displayed in the individual
RTD data fields on the LCD display. See example below.
Coded RTD error messages on individual RTD display example.
Coded RTD error message definitions.
* E203 - DDA tank gauge temperature under-range
* E204 - DDA tank gauge temperature over-range
* E205 - DDA tank gauge internal electronics failure
* E206 - DDA tank gauge internal electronics failure
* E207 - DDA tank gauge shorted RTD element
* E208 - DDA tank gauge open RTD element
* E211 - DDA tank gauge internal electronics failure
* E212 - DDA tank gauge RTD processing disabled
* NA - RTD not active
NOTE
*NA is displayed in respective fields for DDA tank
gauges with less than five RTDs.

NOTE
Due to LCD display space limitations, system error
messages are shown on volume and individual RTD
display mode screens as *L ERR and *T ERR. See
