Meter Verification Procedure

Meter Verification Procedure

  • A reasonable investigation and justification should be made for the verification of a device. On request, an Augos support representative will do a thorough remote investigation to confirm what further action is required
    This includes: 
  • 3 months Bill Verifications (only applicable to billing points)
  • Confirmation that the correct tariff has been applied on Augos. (only applicable to billing points)
  • Confirmation That the NERSA tariffs loaded to our platform match what the municipality/Landlord/Eskom have charging. 
  • Raw data Inspection to confirm the following issues are not present
  • Voltage connection issue
  1. Missing phases
  2. No Neutral Connection 
  • CT Connection issue 
  1. Missing Phases 
  2. Negative Polarity 
  • Mismatch of source of Voltage and CT connections
  • Note:
  • The remote investigation for existing Augos clients, with a valid service agreement and up to date monthly invoicing, is done at no expense to the customer. 
  • Should the remote investigation find the cause of inaccuracy, a quote will be supplied to the customer for any remedial work required. 

  • Once the remote investigation has been concluded, if no obvious problems have been found, and the potential inaccuracies have not been dispelled, a quote will be supplied to the customer for a site investigation, which will include: 

  • Visual inspection of the meter and metering equipment in order to confirm the following issues are not present: 

  • Device hardware failure:
  1. Damage due to outside forces. 
  • Incorrect System Setup: 
  1. Incorrect CT ratio applied 
  2. Incorrect VT ratio applied 
  • Installation fault: 
  1. Voltage connection issue
  • Missing phases
  • No Neutral Connection 
  • Floating Neutral
  • CT Connection issue 
  1. Missing Phases 
  2. Open Circuit CT’s
  3. Parallel instead of Series Connection
  4. Negative Polarity 
  5. Incorrect Summation connection
  • Mismatch of source of Voltage and CT connections
  • Some issues may not be obvious with a visual inspection. These include:     
  • Device hardware failure:
  1. Manufacturing  defect. 
  • Device Software Failure: 
  1. Damage due to outside forces. 
  2. Manufacturing  defect. 
  • Installation fault: 
  1. Device installed in the incorrect location.
    (Site knowledge and wiring diagrams may be needed to determine this.)


  • If neither the remote or site investigation showed obvious problems, and potential inaccuracies have still not been dispelled, a quote will be supplied to the customer for a 7 day Logging exercise. 


  • A standalone data logger will be installed for a period of 7 days. 
  • The data will then be compared to the Augos metering data for the same period. 
  • A report will then be supplied to the customer showing the variance between the logger and Augos meter. 
  • If a significant variance exists, Argos support staff will quote the customer on the required remedial work.
