There are two kinds of error conditions in the U-IV, critical and non-critical.
Critical error conditions cause the U-IV to go to a fault state loop current and
scroll a message across the display. Non-critical error conditions allow the
unit to continue normal operations, but scroll a message across the display
to indicate to the user the nature of the non-critical faults. Most non-critical
errors are the result of a transient condition affecting a very small number
of readings and are not indicative of a failure but informational only.
Below is a list of all the critical errors that can occur in the U-IV:
