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: How do you read a three-phase kWh energy Meter?

These dials measure the number of kilowatt-hours (kWh) you use in 1s, 10s, 100s, 1,000s and 10,000s. To correctly read your meter, read the dials in order, starting from the right and moving to the left. Write down the numbers from right to left. In most cases, the pointer will be between two numbers on the dial.
