Setting The Scaling - Toho Electronics TRM20A Operation Manual

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
The content of the display is different according to the scaling of setting.
⑧No selected range
Channel No.
①
The set channel is selected. (The selection range becomes CH13
Scaling
②
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
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%.

Note: In about 0 points, please note that the digital instruction value might stagger because of the
scaling magnification and the display digit.
