Measurement sections (Un\G100 - Un\G2999)

This product divides the measuring data into the "Data" and "Multiplying factor", and output them to Buffer
memory.
Actual measuring data is obtained by the following formula.
Measuring data = Data × 10
(Example) Average current
The values output to the Buffer memory are as follows when average current is measured 123.456A.
Data (Un\G218, 219): 123456
Multiplying factor (Un\G200): -3
The actual measuring data is obtained from the value of Buffer memory as follows.
Measuring data = Data × 10
= 123.456A
5.3.1 Multiplying factor of electric energy and reactive energy (Un\G100)
Multiplying factor of electric energy and reactive energy are stored.
How to determine the multiplying factor, refer to "3.4.1(3)".
(1) Details of stored data
(a) Storage format
Data is stored as 16-bit signed binary in the buffer memory.
・Data range: -5 to -1
(b) Update timing
It will be updated when phase wire system (Un\G0), primary voltage (Un\G1), and primary current (Un\G2),
primary voltage of VT (Un\G5), secondary voltage of VT (Un\G6), primary current of CT (Un\G7) are set.
n (Multiplying factor is n).
