4. SETTING SCALING VALUES
■
INPUT SCALING
Input scaling means setting an input value within the setting range of the selected input type.
The input scaling values include Zero and Span.
• Input scaling value Zero is minimum value (0%) of input signal.
• Input scaling value Span is maximum value (100%) of input signal.
e.g. Input signal 0 – 20 mA AC
Input scaling value Zero
Input scaling value Span
0 mA
20 mA
IMPORTANT
• Set ‘input scaling value Zero < input scaling value Span’.
• Setting beyond the setting range of the set input type is not available.
• Input scaling value Zero and input scaling value Span can be adjusted by applying actual input signals. Refer to 33.1
TEACH CALIBRATION for details.
■
DISPLAY SCALING
Display scaling means setting a value to display actually.
The display scaling values include Zero and Span. A decimal point can be set in any position.
• Display scaling value Zero is a display value for the input scaling value Zero.
• Display scaling value Span is a display value for the input scaling value Span.
• Decimal point position can be set in common for both display scaling value Zero and Span.
e.g. Display value 0.00 – 600.00 A AC
Display scaling value Zero
Display scaling value Span
Decimal point position
0.00 A
600.00 A
000.00 (2 decimal places)
