Eng. Range
Set up physical representation of the upper and lower input range values. This setting determines the momentary
value unit displayed on the digital displays while recording. For a temperature input, this setting is greyed out.
Eng. range
Max. 6 digits including a decimal point and minus sign
Caution !
The maximum data range handled by the 73VR21x is from -1 x 10
10
to 1 x 10
10
. Engineering range
must be within these limits. Any input out of this range is handled as errors.
Plot position
Determines the display range on the chart when ‘Normal’ is selected at ‘Normal / Log.’ Log’s detailed setting including
the display range is conducted in the Exp. scale. The plot position setting is effective on the Trend view, the Bargraph
view and bargraphs on the Overview.
Set up the upper and lower display range values using the keypad. It is usually the same as the engineering unit
range, but is set to a different range when you want to enlarge a part of the range to view details.
‘e’ can be used to input an exponential value such as ‘1e9.’ Entering ‘e’ in any other way (e.g. ‘1ee’) will not be recog-
nized as a numeral.
Plot position
Max. 6 digits including a decimal and minus sign
For example, if you have a temperature input:

This is the most common setting. Eng. Range and Plot
Position values are the same. Scales are -270°C at the
left edge, 1370°C at the right edge of the chart.

UPPER LIMIT
This is used when you want to enlarge a particular sec-
tion of the Eng. Range. The chart is used only for a nar-
rower range of 1000°C, between 0°C at the left edge and
1000°C at the right edge, against the 1640°C full-scale.

The plot range of a particular channel can be reflected on the scale bar (engineering unit scale). For example, if you
have a plot range of 0 (lower limit) to 1000 (upper limit), the scale bar shows 0, 100, 200 .... 900, 1000, the full-scale
range (0 to 1000) divided by ten.
Scale shift
Plot positions can be shifted in parallel on the trend chart. This function is useful when multiple graphs are overlap-
ping. You can separate the plot positions while no other data is changed.
Scale shift
Selectable within -100 to 100%
10% shift
20% shift
