About the Scaling
Function
Use the scaling function to convert the measured voltage units output from a
sensor to the physical units of the parameter being measurement.
Hereafter, “scaling” refers to the process of numerical value conversion using the
Scaling function.
Gauge scales, scale values (upper and lower limits of the vertical axis) and A/B
cursor measurement values can be displayed in scaled units. Scaling is avail-
able for each channel.
Scaling Setting Example
See When using a clamp sensor (p. 126) (Example: Converting [ V ]

[ A ] )
When using the Strain Unit (p. 127) (Example: Converting [

]

[ G ])
Scaling Methods
Two scaling methods are available:

When scaling is enabled, the space between the brackets [ ] is widened.
Before Scaling After Scaling
Set the physical value per volt (conversion
ratio: eu/V) of the input signal, an offset value
and measurement unit name (eu: engineering
units) for conversion, so measurement values
acquired as voltage are converted to the speci-
fied units.
Example:
Conversion ratio: A value per volt,
Offset value: B, Unit name: A

(Example: Converting [V]

[A])
Set the voltage values of two points of the input
signal, the converted unit value of these two
points and the name of the converted measure-
ment units, so measurement values acquired as
voltage are converted to the specified units.
Example:
Unit name: A
