Acquired values through MODBUS RTU.

The indication values does not correspond to the acquired values through MODBUS.
Category : 

Answer

The acquired value by communication should be multiplied by the multiplying factor to change into the measurement value.
Please refer to Section 7.3 of the Specification “LSPM0075” for the multiplying factor.
Example)
When the primary current is 4000 A or more and the indication value of ME96 is 1234 A,
• Acquisition data of the register address “768” (current value) is 123, or
• Acquisition data of the register address “754” (multiplying factor) is 1.
Therefore, the acquisition data is
  123 x 101 -> 1230 A.
The indication value is rounded to nearest tens. Therefore, a difference may arise between the indication number and the acquisition data through communication.
