11.2. Scale
[Scale] programming is necessary when a voltage input from a converter, etc. is displayed on an actual scale.
However, the scale is programmed with the same characteristic scale (not linearized scale) as voltage input.
This programming is also necessary when the decimal point position is changed in thermocouple or
resistance thermometer input channels.
By pressing + keys from the operation screen, the scale programming display appears.
1. Programming scale
This is the actual scale (physical quantity) programming to the
printing range being programmed in [range/printing range].
2. Copy of printing range
By programming [range/printing range], the printing range reflects
(copies) to the programming value of the scale.
If the scale copied from the printing range is used, the decimal
places programmed by the printing range are neglected and
the measured values with fixed decimal places by range
number are displayed and printed. The following table shows
the cautions to be observed according to the input types.
Assume that range No.03 (
±
69mV)
and printing range of 0 to 50(mV) are
programmed to 0 to 100(
ℓ
/min)
In case of voltage ranges In case of temperature ranges
Scale programming is not required when the
scale is equal to the printing range, but be
carefull with the decimal places of scale.
Since the printing range is copied to the scale, no
programming scale is necessary, but the decimal places
of measured value are fixed by range number.
For changing the decimal places, refer to 3.

Note 1: Decimal places of measured value are fixed
by range number when the printing range is
equal to the scale.
Note 2: Decimal places of programmed scale become
effective because different decimal places are
programmed on printing range and scale.

Note 1: Conforms to the decimal places rule.
If the decimal places of the lower-limit value and
higher-limit value are different, the decimal places,
whichever is smaller, is adopted.
(Example)0.00 to 100.0
0.0 to 100.0
The decimal point does not light in channels 1 to
3 display when 3 decimal places are programmed.
(This does not affect any data printing) Assume
that the decimal point exists at the lower
significant 3 digits.
The [Copy] function is convenient. Refer to par. 11.13.
