A100C - BS Single Phase Electronic Meter
_____________________________________________________________________________

Reverse Energy Event Flag

The Reverse Energy Event Flag is set when an event occurs as defined in Reverse Run
Count.
This can be inhibited at manufacture if required. Once detected, this flag will remain set
until the power to the meter is removed, then restored.

Reverse Energy Reading

Irrespective of whether the meter is set to import only or power flow insensitive mode,
reverse kWh power flow can be independently recorded and displayed.
11.2.2

Power Fail Counter

A count of the cumulative number of power downs is stored to a maximum of 65535.
The register will then roll over to 1.
11.2.3

Time - Rate 1 and Rate 2

Each complete hour the meter is active in Rate 1 and Rate 2 is recorded in separate
registers.
A count of 999999 is recordable. The register will then roll over to 1.
11.2.4

Cumulative Time in Anti-creep

This feature detects and stores each full hour the meter is in kWh anti-creep mode.
This detects abnormal consumer load patterns.
11.2.5

Watchdog Reset Counter

The Watchdog Reset Counter stores a count of the occasions when the CPU is restarted
due to abnormal operation. The maximum count is 255.
11.3

Power Flow Insensitive Mode

For import meters the meter can be configured (at time of manufacture) so that the kWh
registers (Cumulative, Rate 1, Rate 2) increment for both import and export energy
consumption. The pulsing LED indicates identically for both import and export.
The reverse energy event flag, reverse energy event counts and indicators operate in the
same manner in power flow insensitive mode.
