Length: 2 Registers (4 bytes)

Range: +1,048,576 V2 / 0 V

2 or +65536 I2 / 0 I2(1262 or 1272)

Unit: 1/4906 V2 secondary or 1/65536 A2 secondary (1262 or 1272)

These registers together are a four-byte unsigned integer. Conversion into secondary voltage or current involves multiplying by the appropriate scale and taking the square root of that value.

Depending on the unit and hardware, the range and unit of voltage reading differs. For a Nexus® 1262/72 meter, the range goes to +1,048,576 V

2 with a

unit of 1/4096 V2.
