8.9 Errors and Cautions
The SGM3000 Series meters continually checks for internal errors, hardware failures, and
cautions. These events are reported in coded form on the LCD.
Error Reporting
The meter continuously checks its hardware components
—
ROM, EEPROM, flash, battery,
metering chip, and microprocessor
—
to ensure that they are operating properly. When the
meter detects that a hardware component is not operating properly, an error is reported. Error
codes are displayed as soon as they are detected. The meter can be programmed to freeze
error codes in the display when an error is detected. Refer to Table 8 for a list of errors. If
subsequent tests indicate that the hardware component is operating properly, the meter will
clear the error automatically.
Errors are serious events and usually indicate a condition has occurred that may have
compromised the meter data. Unless Aclara has issued a service advisory indicating that other
actions should be taken, you should remove the meter from service and contact your Aclara
sales representative.
