The acquired digit length of “1280”, “1281” and “1304” varies with the full load power.
The acquired digit length of “1304” is 6-digit. Each of “1280” and “1281” acquires 3-digit which 6-digit of “1304” is distributed into. 

The unit of “1408” (including “1390” and “1426”) is fixed.

Please refer to the Specification “LSPM0075”.
 

Example)
When the measurement value is 3,210,987.654 kWh, the communication data is the following:
[When the full load power is less than 10 kW]
• Register address: “1304” --> 098765
• Register address: “1280” --> 765
• Register address: “1281” --> 098
[When the full load power is 10 kW or more and less than 100 kW]
• Register address: “1304” --> 109876
• Register address: “1280” --> 876
• Register address: “1281” --> 109
…

[When the full load power is 1,000 kW or more and less than 10,000 kW]
• Register address: “1304” --> 321098
• Register address: “1280” --> 098
• Register address: “1281” --> 321

[Regardless of the full load power]
• Register address: “1390” --> 210987654 (Fixed unit is Wh.)
• Register address: “1408” --> 003210987 (Fixed unit is kWh.)
• Register address: “1426” --> 000003210 (Fixed unit is MWh.)
When the software of the upper system supports the 4-byte data, we recommend the register address of “1408” (including “1390”and “1426”).
