What causes meter errors?

Those are some of the most common prepaid meter error codes that South Africans face on a daily basis. But what causes these errors? Communication issues between the CIU and the meter are probably the biggest culprit in this regard.

The customer interface unit (CIU), or User Interface Unit (UIU) is the device that you use to interact with your meter. The actual meter is outside your home. So, the two need to communicate in order for various functions, such as loading a token, to be effected.

Communication happens either wirelessly or using the electricity cables running from your home. Should there be interruption somewhere along the line, you will end up having serious issues.

Other errors are caused by meters that have not been initialized, or ones that have not been paired with the CIU. In any case, all these errors are easy enough to solve.
