  • Image Verification Successful. A firmware download verification has completed successfully.
  • Image Verification Failed. A firmware download verification has not completed successfully.
  • Image Activation Initiated. A firmware download activation has been initiated.
  • Image Activation Successful. A firmware download activation has completed successfully.
  • Image Activation Failed. A firmware download activation has not completed successfully.
  • Improper Installation Detected. This event occurs when the ERT cannot adopt configuration information.
  • Initial Index. This event occurs when the initial index metrology parameter is changed.
  • Inter Digit. A corrupt digit exists within the encoded register reading.
  • Invalid Read. The register is not sending a valid read.
  • Inversion. Detects when the meter is installed upside down and has power applied.
  • Key Signing. This event occurs with an application level security failure for certificates.
  • Key Update. This event occurs when the key is updated in the device.
  • Last Interval is Sum (water). The last interval returned with a datalogging interval read is a summation.
  • Leak Detection (water). Detects after flow is continuous over seven days (no zero-consumption intervals). The flag is reset to zero on the next zero-consumption interval.
  • Leak Detection/Reverse Flow (water). Indicates that both Leak Detection and Reverse Flow conditions exist. The indicator changes when one condition no longer exists and resets to zero when both conditions no longer exist.
  • Leak Meter Alarm. Event detail is not available.
  • Leak Sensor OK (water). If 1, the endpoint has a leak sensor attached and is working properly. If 0, the ERT module has a leak sensor attached, but it is not communicating.
  • Legally Relevant Event Log Nearly Full. The Legally Relevant Event Log is at 90% of its total capacity.
  • Load Profile Cleared. This event occurs when the Load Profile object is cleared.
  • Low Pressure Alarm. The meter has detected minimum meter pressure.
  • Low Temperature Alarm. The meter is currently at its minimum operating temperature.
  • Low Battery. An electric meter has a low battery warning or an end-of-calendar warning. A water ERT module has a low battery.
  • Low Battery/Detached. Indicates a low battery condition or detached condition.
  • Magnetic. Detects presence of external magnetic field.
  • Manual Time Sync. This event occurs when the time has been changed manually.
  • Meter Error. Meter has an error or warning that can affect billing date (for example: carryover error).
  • Meter Removal. Detects when the tilt detector is activated within two seconds after power loss.
  • Meter Temperature Alarm. Event detail is not available.
  • Meter Tamper. Event detail is not available.
  • Meter Warning. Meter has a warning that may require a site visit, depending on utility practice (for example: reverse energy flow warning).
  • Meter Quiet Mode Exit. The event occurs when the ERT first detects pulses or detects consumption.
  • Not Current Read. The read returned is not the current read (date/time).
  • PCOMP Changed. This event occurs when the PCOMP metrology parameter is changed.
  • Prescaler Changed. This event occurs when the prescaler metrology parameter is changed.
  • Pulser/Encoder (water). If 1, using an encoder; otherwise, using a pulser.
  • Pulse Mismatch. The ERT detects an internal pulse mismatch.
  • Register Error. Communication with the register cannot be completed.

  • Removal (electric and gas). Meter has been removed.
  • Removal(water). Detects a number of problems including cut cable, poor communications, corrupt data, or that the ERT module was removed from the meter.
  • Replay Attack Detected. This event occurs with an application level security failure for replays.
  • Restart. This event occurs with a planned restart of the ERT.
  • Reverse Flow. Detects when an hourly index value is less than the previous hourly value. The flag remains set for 40 days. The 40-day counter restarts upon each occurrence of a reverse flow event. The value resets to zero after completing a 40-day cycle with no additional reverse flow occurrences.
  • Reverse Flow End. The ERT detects the end of a reverse flow after the reverse flow was reported.
  • Reverse Flow Meter. Event detail is not available.
  • Reverse Rotation. Detects when the meter disk rotates backwards for more than four revolutions.

  • Tilt Debounce Parameter Changed. The parameter not related to the meter reading is reprogrammed.
  • Time Sync. This event occurs when a time change is greater than the warning level threshold.
  • Valve Tamper. The valve has been tampered with or removed
  • Zero Consumption Detected. The meter has detected no usage.
