11. OTHER PROGRAMMING
11.2 Scale
“Scale” programming is necessary to display a voltage input from a converter, etc. with an actual scale. However,
the scale is programmed with the same characteristic scale (not linearized scale) as the voltage input. This
programming is also necessary when the decimal point position is changed in thermocouple or resistance
thermometer input channels. Press and simultaneously in the operation screen to display the
“scale” programming.

Programming Scale
This is the actual scale (physical quantity) programming for
the printing range being programmed in the [Range/Printing
range].
2
Printing range will be copied
When programming the [Range/Printing range], the printing
range is copied to the programming value of the scale.
If the scale copied from the printing range is used, the decimal
point positions programmed by the printing range are neglected
and the measured values with decimal point positions fixed by
range number are displayed. The following table shows the
cautions to be observed according to the input types.
Range No.03 (
±
69 mV)
Printing range: Changing the
programming from “0 to 50 (mV)” to “0
to 100 (litter/min)
Voltage ranges
Temperature ranges
Scale programming is not required when the scale is
equal to the printing range. They are copied to scale
programming, but be careful with the decimal point
positions for the scale. See item
3
.
Since the printing range is copied to the scale, no
programming scale is necessary, but the decimal point
position of the measured value is fixed by the range
number. For changing the decimal places, refer to

Note 1: Decimal point position of the measured value is fixed
by range number when the printing range is equal to
the scale.
Note 2: Decimal point positions of the programmed scale
become effective because different decimal place are
programmed on printing range and scale. See item
(2).
(2) When the scale is programmed with a different value from
the printing range.
The decimal point position of the programmed scale
becomes effective.
Note 1: Due to the decimal point
position
rule.
If the decimal point positions of the lower-limit and higher
-
limit values are different, the lower decimal point
position is adopted. <Example> 0.00 to 100.0
0.0 to 100.0
The [Copy] function is convenient. See Section 11.14.
