How to read a meter

Methods to see the degree of the meter: find where the meter degree, distinguish the degree of color, specific readings

1, to find where the meter degree

If the user is using a mechanical meter, then you should first find the degree of the meter, the mechanical meter of the meter. The display will usually have a set of data, this set of data is the current total electricity consumption of the meter.

2, distinguish the degree of color

When we look at the meter degrees, should be in accordance with the order of the left to right to see this set of data, and the data are generally divided into black and red, where the black area from left to right on behalf of the 10,000th, thousandth, hundredth, and digit, and the red area is represented by the decimal places.

3, specific readings

If the value of the black area is 14564, the red area of the value of 3 words, it represents the meter degrees, 14564.3 degrees.

Types of meters

1, mechanical meters

Mechanical meters belong to the traditional meter, mainly through the mechanical gear drive counting, used to indicate the power consumption. Driven by worm gears and gears to show power.

2, induction meters

Induction meters are mainly measured by mechanical equipment, stability and measurement accuracy is relatively poor, the need to rotate the aluminum plate in the measurement, resulting in high electric power consumption, can not prevent theft of electricity and other abnormal use.

3, electronic meters

Electronic meters are smaller and lighter than induction meters, high precision, small environmental impact, the use of chip measurement methods, the power consumption is reduced.

4, plug-in prepaid meters

Plug-in prepaid meters and electronic meters are similar to the principle, but also more charging control function. In use, the need for "pre-charge" operation, no need for manual operation, for the user's power consumption correction is very convenient.
