Note
• If the scales of multiple channels are set to the same position, the scale of the channel
assigned first to the group is displayed.
Example: If the order of assignment of a group is 003.002.001, and the scale display
position of all channels is set to 1, the scale of channel 3 is displayed at display position 1.
• Even if some of the scale display positions are skipped, the scale is packed towards display
position 1.
Example: Suppose the assignment of channels to a group is 001.002.003, and the display
positions of the scales are set to 1, 3, and 6, respectively. The scales are actually displayed
at positions 1, 2, and 3, respectively.
• The scale is divided into 4 to 12 sections by the main scale marks. The section between
the main scale marks is divided into 5 or 10 subsections by medium and small scale marks.
However, small scale marks are not displayed in the following cases.
• When the resolution of the input range is smaller than the total number of small scale marks.
• When zone display is used.
• When partial expanded display is used (numbers are displayed at the ends of the scale
and at the boundary position).
• The scale values are displayed according to the following rules.
• If the number of scale divisions is 4 to 6 for the vertical trend display, values are
displayed at all main scale marks. If the number of scale divisions is greater, the values
are displayed at every other main scale marks.
• Scale upper and lower limits are displayed at the ends of the scale.
• Scale values are displayed up to 3 digits excluding the minus sign. However, if the
integer part of values at the ends of the scale is both 1 digit or the integer part is zero, 2
digits are displayed.
Example: If the scale is –0.05 to 0.50, the lower limit is “–0.0” and the upper limit is “0.5.”
• If the integer part of either end of the scale is 2 or 3 digits, the fractional part is truncated.
Example: If the scale is 0.1 to 100.0, the lower limit is “0” and the upper limit is “100.”
• If the integer part of either end of the scale is 4 or more digits, the value is displayed
using a 3-digit mantissa and exponent like “×10” or “×10 2 ”.
Example: If the scale is 10 to 2000, the lower limit is “1” and the upper limit is “200 × 10”.
• The unit is displayed near the center of the scale. If partial expanded display is used,
the display position is offset from the center. For the vertical trend display, the number of
characters that can be displayed is up to six. For the horizontal trend display, the number of
characters that can be displayed is up to three. However, if the scale digit display is set to
Fine, up to four characters are displayed.
• Trend > Scale > Digit
Fine: For example, if the scale range is “49.0 to 50.0” and you select “Normal,” the
scale values are displayed using 2 digits (“49” for example, see Note above). If you
select “Fine,” the scale values are displayed using 3 digits as shown below.
• Trend > Scale > Value indicator
The current value is displayed as a mark or a bar graph.
