Scale Bar
Two scales, linear and square root from 0 to 100%, are indicated on the scale bar. The scales apply to the plot range
specified in Pen Setting. With the perpendicular graph, the right scale is linear and the left scale is square root.
Engineering scale for a specific pen can replace the standard scale by touching the tag name for the pen (max. 3
decimal places). If you want to the scale with fractions, specify the decimals for the plot range in Pen Setting. In
order to return the scale to 0 to 100%, touch the scale.
While recording, red lines are shown at the upper and lower edges of the scale bar.

DIGITAL DISPLAY
Digital displays include the tag name and/or instantaneous value or status as specified (Tag + Value, Tag, or Value)
in Digital Display Type (See 3.6). When an alarm is set for the pen, the alarm status is also indicated.
Engineering Unit Value or Discrete Status
Analog instantaneous values indicated in engineering unit are renewed by the specified display rate. Voltage inputs
are indicated as precise as two decimal places, and temperature inputs are as one decimal place.
Discrete status is indicated with the display description specified in the Pen Setting.
Alarm Status
Analog alarm indicators are placed only when analog alarm setpoints are preset. With a lower (low) alarm triggered,
the left indicator’s color changes from Normal to Alarm color specified in the Pen setting. With an upper (high) alarm
triggered, the right indicator’s color changes likewise.
For discrete signals, the alarm indicator colors are determined according to the Pen setting, regardless of the alarm
setting.
Only one (1) digital display can be specified to appear in large size.
Touch twice the digital display of the pen you want to enlarge. The scale changes to the engineering unit of the pen
at the first touch, and then the large display appears at the second touch. In order to reduce the display size to the
original state, touch the large display once again.
