Use when minus value is not required. Lower 3 digits of displayed value are set regardless of decimal point position.
Note: With the low-end cutout or absolute value low-end cutout set to ON, the low-end cutout value setting is valid.

• Input scaling
Zero and full scale of input range can be re-configured to user's desired value by entering parameters.
When initialization of setting is executed, these data is lost and return to the default value.
Input Scaling Value A:
Input value for zero point
(Input scaling value A < Input scaling value B)
Enter the value you want to set to zero in the measurement range.
Input Scaling Value B: Input value for full scale point
Enter the value you want to set to full scale in the measurement range.
• Display scaling
Display Scaling Value A:
Display Scaling Value B:
Display value for Input Scaling Value A
Display value for Input Scaling Value B
• Normal Scaling
The display value increases when the input signal increases.
• Inverted Scaling
The display value decreases when the input signal increases.
