6.3 Possible Setting Range for Maximum Scale
The maximum scale of current can be selected from about 40% to 120% of rating, and maximum scale of voltage can be
selected from about 20% to 250% of rating, and maximum scale of active power and reactive power can be selected from
about 20% to 120% of rating. But for the convenience of scale conditions, the values in the following tables are applied.
Also, this is same as with corresponding measured values for maximum scale of analog output.
■
Current maximum scale value
Possible setting range:-10 STEP to +3STEP of the rating
Example: When the rating is 100A, the value is from 45A to 160A.
Current maximum scale value (1/3)
Current maximum scale value (2/3)
Current maximum scale value (3/3)
