2.7.2 DETAILED SETTING
Figure 2.7.2. Detailed setting, analog.
Analog type and Input range
With 100 msec. storing interval, only DC voltage ranges are selectable
Selectable signal types and input ranges are as shown in the tables in the following page. For DC input, choose the
upper and lower range values (0% and 100%) within the measurable range. For temperature input, the input range
is equal to the measurable range, thus fixed.
‘e’ can be used to input an exponential value such as ‘1e9.’ Entering ‘e’ in any other way (e.g. ‘1ee’) will not be rec-
ognized as a numeral.
Input range
Max. 6 digits including a decimal point and minus sign
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.
‘e’ can be used to input an exponential value such as ‘1e9.’ Entering ‘e’ in any other way (e.g. ‘1ee’) will not be rec-
ognized as a numeral.
Eng. range
Max. 6 digits including a decimal point and minus sign
Plot position
Determines the display range on the chart when ‘Normal’ is selected at ‘Normal / Log.’ Log’s detailed setting includ-
ing the display range is conducted in the Exp. scale.
Set up the upper and lower display range values. 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 rec-
ognized as a numeral.
Plot position
Max. 6 digits including a decimal and minus sign
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 0 to 100%
Normal / Log
When Normal plotting is selected, the plot area is divided equally. When Logarithmic is selected, the plot area is
divided in specified scale of exponents of 10.
For Logarithmic plotting, specify the lower limit of exponent in ‘Logarithmic Plot Position Exponent’ field within -9 to
8, and how many divisions you wish to have in ‘Exponential Scale’ among 10, 5, 4, 2, and 1.
Square Root
Input data is square-root-extracted when this setting is enabled.
Overview Color
Specify the bargraph color for the pen in the Overview. Use the color palette.
