Everybody help me have a look. What do you think of this kind of electric meter? The broken property took back my old watch and replaced it with this one. I can't even understand it.

Three small red lights are vertically arranged on the left side of the screen, representing "total usage, 1 and surplus" from top to bottom respectively.

Three small red lights are vertically arranged on the right side of the screen, representing "alarm, switch and pulse" from top to bottom.

The picture shows the overhead light on the right side, indicating "alarm". It shows that the ammeter is in alarm state, which may indicate that the battery is running low.

The picture shows the top light on the left side, which means "always used". The number currently displayed by the display meter is the total, which seems to be 29. 13, which means that the total electricity consumption in the latest counting period is 29. 13 kWh.

I don't know if the three small red lights arranged vertically on the left side of your meter light up alternately, that is, when the card is not inserted, the meter displays the total consumption, 1 and the remaining amount alternately. I don't know what this circle 1 means yet.

If the "Remaining" light lights up when the card is inserted, the screen shows the remaining power of the blood glucose meter.

The digital display at the top is more traditional and simple. The "00 129" on the left is black, and it is 10000, 1000, 100, 10, respectively. The 4 on the right is red, which is one digit after the decimal point, and the red 4 represents 0.4 degrees. The total is 129.4 degrees. This is the total number of times the meter has been used after it has been returned to zero and put into use.
