Non-recoverable errors are generated from internal test failures that are catastrophic (or from promoted
recoverable errors). The error code and any appropriate icon will be displayed along with the “[X]”
Instrument Malfunction icon.
The only way to continue at this point is to reset the electronics by removing the batteries.
NOTE: The error codes E2.1, E2.3, E3.0, E3.1, E3.2 and E4.1 can sometimes be caused by a faulty probe.
It is advisable to remove probe completely from instrument and check functionality as described in the Setup
section on page 4 before assuming an instrument problem instead of a probe problem. If another probe is
available, this can prove useful in tracking down the source of the problem.
