What is Tamper code on prepaid meter?

Tamper Mode is a security feature on prepaid meters that is designed to detect and prevent unauthorized access or manipulation to the meter. When the meter’s tamper code is triggered, the meter locks up and may stop supplying power until the issue is resolved.
This means that when there is any form of tampering or external influence on the meter environment or circuit, the tamper code will be activated. Once this code is triggered, your meter may not be able to supply power again, leading to a temporary disruption in your energy supply until it is fixed. In the simplest term, the tamper is an inbuilt security feature that meter manufacturers designed and included into the meter to prevent external influence or unauthorized access to the prepaid meter.
Cause of Tamper Mode on Prepaid Meter
There are different factors that cause tamper mode on prepaid meters, such as:
- Opening the meter casing or cover
- Unauthorized access to the meter
- Fault in the prepaid meter or poor electrical wiring
- Power surges or interruptions
- Incorrect meter installation
Let’s discuss them one after the other
1. Open Meter Cover
One of the major factors that can trigger a tamper code on a prepaid meter is an open meter cover. If you open the cover or casing of your prepaid meter, it’ll trigger tamper mode, leading to an interruption in power supply. So, to avoid it, you should always avoid opening your meter cover, ensuring that it is closed always.
2. Unauthorized access to the meter
Another common factor that can also trigger your prepaid meter to go into tamper mode is unauthorized access to the meter. When there is illegal access to the meter, the meter will be forced to go into tamper mode to prevent illegal access. This means that you shouldn’t try any illegal thing like bypassing your meter so that it won’t go into tamper mode.
3. Fault in the prepaid meter or poor electrical wiring
A faulty prepaid meter or poor electrical connection in your property can also force your meter to go into tamper mode. If your prepaid meter is faulty or your electrical connection is faulty, your meter may go into tamper mode to protect itself from damage or external interference.
4. Power surges or interruptions
When there is a sudden or abnormal power surge or interruption, your prepaid meter’s tamper mode may also be triggered, forcing it to stop supplying power.
5. Incorrect meter installation
If your prepaid meter is not installed properly, it may also lead to tamper mode, indicating the danger of incorrect meter installation. So, you should ensure that your meter is properly installed by certified technicians to prevent the meter from entering tampering mode.
