A fatal error indicates an internal meter problem, which ceases all meter functions except
communications. These errors cause the display to lock on the error code until the meter is
re-initialized.
The non-fatal errors can indicate either a meter problem such as low battery error or a site
problem such as the loss of phase voltage error. The non-fatal self-diagnostic checks can be
independently enabled or disabled through the PC-PRO+ Advanced software.
SiteScan Toolbox Mode
SiteScan Toolbox
Mode displays all the metering information used by the meter for
individual phase measurements and system and installation diagnostic checks. This
information helps the user verify that the meter is installed and operating correctly. The per-
phase RMS voltage and current readings along with both voltage and current angle readings
let the user check the meter’s site phase sequencing performance. The diagnostic counters
alert the user to the frequency of a metering installation or tampering problem. The
combination of a diagnostic error and the information in the Toolbox
Mode display will
greatly enhance the ability to diagnose and resolve metering or tampering issues.
