Q1: What are the advantages of digital energy meter?
The meter has protection against undesired input range. Hence the meter can be protected from overload or some of the fault or misuse. The auto polarity function can prevent problems from connecting the meter to a test circuit with some wrong polarity. Overall accuracy is increased due to digital readout.

Q2: What is the difference between a power meter and an energy meter?
A2: One major difference between a wattmeter and an energy meter is that the wattmeter measures electrical power in the circuit, whereas the energy meter measures total amount of energy consumed by the load.

Q3: What is the main function of an energy meter?
A3: An energy meter is an electrical device that measures the electrical power being consumed and this allows the energy consumed over time (by a residential building, a business, or an electrically powered device) to be determined.

Tips: What do I need to pay attention to in the installation of electricity meters?

  • The installation site of the energy meter should be dry, convenient for reading, and free of any dust, heat source, mechanical vibration or magnetic interference(The lead with a distance of over 100A should not be smaller than 400mm). The distance to the heat distribution pipeline should not be smaller than 0.5m. If it is installed outdoor, rain-proof measures should be taken. 
  • The power circuits of different power prices should be installed with the meters separately. The power circuits of the same power price should be installed with the meter in a combined manner.
  • The energy meter should be installed vertically. The front, rear, left and right inclinations are not more than 2°. The center of the energy meter is generally 1.5~1.8m away from the ground. The incoming line is connected to the power while the outlet is connected to the load. The three-phase energy meter should be connected to the circuit in the positive phase sequence and wired according to the wiring diagram on the terminal cover.

Bought a new replacement energy meter
I have purchased a new single phase digital energy meter to replace the broken one and I am very pleased with its performance. The energy meter was very easy to install and provides an accurate reading of my energy consumption. I appreciate the large digital display which makes it easy to read the energy meter.
