The device diagnostics status is stored in a non-volatile
register, which may be inspected and cleared via Power
Software, from the meter display or from a user application. All
diagnostic events with time stamps are also recorded in the
device Event log and can be inspected via Power Software
(see Retrieving the Event Log in Section 4).
See Diagnostics Display and Reset in Section 3 on how to
inspect and clear the device diagnostics status from the
display. See Viewing and Clearing Device Diagnostics in
Section 4 on how to inspect and clear the device diagnostics
status via Power Software. Refer to the Multi-Mon Modbus
Reference Guide for the diagnostic register address and
layout.
In the event of a device fault, check the fault reason and clear
the device diagnostics. In the event of a time fault, update the
device clock. In the event of a configuration reset, check the
setup affected by the fault via the device Event log, and then
verify the setup data.
Hardware failures are normally non-critical recoverable faults
that do not cause a system failure but may cause data loss.
Hardware failures are often caused by excessive electrical
noise in the region of the device.
If the device continuously resets itself, contact your local
distributor.
