7.6 Setting the scaling
［
Explanation
］
Set the “scaling” and “Square root” when the input kind is “DC voltage” or “DC current”, and set
the “Measure range”, “Scale range”, “Decimal point” and “Unit”.
Note: Scaling can only be displayed when the input type is “DC voltage” or “DC current”.
Note: When the recorder is in recording, the setting cannot be changed.
［
Operation
］
Select the Input CH
key
⇒
Scaling key on the Parameter.
The content of the display is different according to the scaling of setting.
①
Channel No.
The set channel is selected. (The selection range becomes CH13
～
CH48 in the “Calc. CH.”.)
②
Scaling
ON/OFF of “scaling function” and “Square root function” is set.
When the scaling function or the evolution operation function is turning on, the decimal point
position and the unit can be set.
ON
：
The input of the direct voltage and the current is converted into an arbitrary physical
value by using the scaling function.
OFF
：
The scaling function is not used. (The decimal point position and the unit are
automatically set.)
Square root ON
：
The time base range is assumed to be 0
～
100%. The input value is %
converted, and the value is extracting the square root operated.
When the value is a minus, the square root operated result is assumed to be 0%.
Data (0
～
100%) that does the square root operated is converted into measurements as
“0
～
100%” of measurements.
The value up to 1% of measurements is connected from 0 by the straight line.
Note: In about 0 points, please note that the digital instruction value might stagger because of the
scaling magnification and the display digit.
③
Measure value
This item can only be set when the “
②
Scaling” is “ON” or “Square root ON”.
The lower bound value (left) and the upper bound value (right) of the measure range are set.
