User Interface Unit Simulator

Note: For this animation we have used JavaScript ECMA2019 technology. The name already suggests the year of introduction. If it doesn’t work on your PC, it’s likely possible that you need a browser update. Usage with cellphone will be fine. Touchscreen is supported.

By now the UIU/CIU short-codes for STS prepayment meters are not unified. We have collected and merged all recent requests.
A UIU is mainly for end-customer information and for some utility requests I have my doubts. Is the customer really interested in the reactive energy in the second quadrant from two years ago? Check the four quadrant simulation to get a better idea.
Usually utility engineers will read the relevant data by optical port or review them in the AMI system.
In order to come to a standardization I would like to collect all your additional/missing items based on a three-phase meter. Short codes for unsupported items will remain at the same position, but with a ‘not in use’ indication.

The working principle

electronic energy meter CL730S22

During loading of this website the UIU is connected to a virtual meter. This meter is in the field since more than two years and holds all related parameters consistent.
We have initially a tamper mode for demonstration purpose. The tamper can be cleared by using the drop-down menu.

Once the tamper is cleared, the meter starts to run. You can input token with an acceptance probability of 30% or review the parameters.

    1. The meter function of low credit alarm can be set via PC software in local power company.

    1. If the meters shows “tamper”, only your local power supplier can unblock it. You can find more information about the principle here.

    1. The meter is activated by the installation team. In the unlikely event that they have forgotten, the meter activates itself after two hours uninterrupted power supply.

    1. Thank you for your comment. If you input wrong or random numbers, the LCD will indicate Reject-x, x is the times of wrong input. For your more information in detail, please click here.

    1. Thanks for your comment. We strongly recommend you recharge your meter.

    1. It depends on which register you are reading. For example, the sum register for consumption is always incrementing, while the credit register is counting down. If you have an overdraft allowance from your power company, it can even show negative values. If you are curious or in doubt, ask your energy provider to check your meter.

  1.

    1. You need to report to Your power company. They have the tools to check.

    1. The meter expects a token with 20 digits. If you input less, the error 6 occurs.
