How to read the degree on an old-fashioned electric meter
With the popularity of smart meters, old-fashioned meters have gradually faded out of people's sight, but they are still used in many households or areas. Knowing how to correctly read old-fashioned electricity meters can not only help users understand their electricity usage, but also avoid cost disputes caused by misreadings. This article will introduce in detail the reading method of old-fashioned electric meters, and attach the hot topics and hot content on the Internet in the past 10 days for readers' reference.
1. Basic structure of old-fashioned electric meters
Older electricity meters are usually mechanical meters with a set of numeric wheels on the dial that show the current electricity consumption. The number wheel is generally divided into integer digits and decimal digits. The integer digits are black and the decimal digits are red. When reading, only the numbers in the black part are recorded, and the red part is usually ignored.
| Meter type | Number wheel color | Reading method |
|---|---|---|
| Mechanical meter | Black (integer digits), red (decimal digits) | Read the black numbers and ignore the red parts |
2. How to read the degree of an old-fashioned electric meter
1.Observe the meter dial: Find a roulette wheel that displays numbers, usually 5-6 digits, with the first few digits in black and the last one or two digits in red.
2.Record integer digits: Record the black numbers from left to right, ignoring the red numbers. For example, if the dial displays "12345.6", the actual reading is "12345" degrees.
3.Calculate electricity usage: If you need to calculate the power consumption for a certain period of time, you can subtract the last reading from the current reading. For example, if the last reading was "12000" and the current reading is "12345", the power consumption is "345" degrees.
| step | Operating Instructions |
|---|---|
| 1 | Look at the meter dial and find the number wheel |
| 2 | Record the integer digits of the black part |
| 3 | Calculate electricity usage (current reading - last reading) |
