These two meters could both be utilized for measuring two phase three wire or three phase three wire AC active energy. They are processed by SMT and conform to international standards of IEC62053-21 and IEC62052-11.

1. Active energy is measured bi-directionally and reverse electricity will be measured and counted into total electricity.
2. Impulse indicator light will flicker to show working status when passive pulse outputs.
3. Phase loss LED alert light indicator
4. Measurement for phase loss. The metering precision will not be affected at all if any one phase of the two phase three wire meter cut off.
5. Two types of case shells available: Protection I or Protection II.

Optional Function
1. LCD shows two types of electricity bi-directionally. Forward and reverse electricity could be showed separately. (E2302L only)
2. Dead battery alert display (E2302L only) added
3. 48-hour supercapacitor power cut display (E2302L only) added
4. Shell utilizes ultrasonic sealing instead of screw sealing
5. Built-in three phase current and voltage hook. Equipotential anti-tamper design.
