Hioki LR8431-20 - Converting Units (Scaling Function)

3.5 Display Settings
58
Use the scaling function to convert input
voltage to the physical units of the measure-
ment parameter for display, such to convert
voltage input for display as electrical current.
Converted values can be displayed in fixed-
or floating-point notation.

1 For the [Cond](condition) setting, select the
desired numerical notation.
Setting options:( default setting)
2 Move to the next item to the right, and
select the scaling method.
Setting options:( default setting)
3 Enter the [Unit] name on the comment entry
screen.
See: 3.6, "Entering Comments" (p. 60)
4 Ratio: Enter the conversion ratio and offset.
2-pt: Enter the values at two points before
and after conversion.
Dec Displays converted values using fixed-point
notation
Exp Displays converted values using floating-
point notation
Off* Scaling is disabled.
Ratio* Convert by specifying the ratio of physical
units per volt of input signal (conversion ra-
tio), offset, and the name of the units.
2-pt Convert by specifying the input signal volt-
age at two points, the physical unit values at
those points, and the name of the units.

Combining scaling and display positioning (upper/lower limits)
To use both scaling and upper/lower display limits, set the scaling first, then upper/lower limit val-
ues. With scaling enabled, the upper and lower limit setting ranges are constrained as follows:
-9.9999E+19  Setting value-1.0000E-19, Setting value = 0, 
+1.0000E-19  Setting value +9.9999E+19
