8.5 Converting Input Values (Scaling Function)
About the Scaling
Function
Scaling Methods
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 (voltage
axis)) and A/B cursor measurement values can be displayed in scaled units.
Scaling is available for each channel.
Before Scaling
Scaling Setting Example
See: When using a clamp sensor (
When using the Strain Unit (
Two scaling methods are available:
• Conversion Ratio Setting
• Two-Point Setting
Conversion Ratio Setting
Set the physical value per volt (conversion ratio:
eu/V) of the input signal, an offset value and mea-
surement unit name (eu: engineering units) for
conversion, so measurement values acquired as
voltage are converted to the specified units.
Example:
Conversion ratio: A value per volt, Offset value:
B, Unit name: A
Two-Point Setting
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:
Voltage value at Voltage of units to
2 points convert
V : Higher poten- A : Value for higher
H H

V : Lower poten- A :
