When Using the Scaling and Variable Functions Together
When auto-correction of the variable function (p. 307) is enabled (On) (Default setting)
The Variable function settings change according to Scaling and vertical axis (voltage axis) range settings.
Set Scaling before setting the Variable function.
If you change Scaling settings after enabling the Variable function, the Variable setting voltage is
automatically corrected so that the displayed size of waveforms is unchanged.
When auto-correction of the Variable function is disabled (Off)
Set the Variable function after setting Scaling.
If you set the Variable function first, enter post-scaling values (converted physical values).
To display the full span of output from a sensor
By using the Scaling and variable functions in combination, voltage from a sensor can be converted to the
physical units of the measurement object.
(Example)
Set Scaling as follows:
Scaling: Decimal or exponent, Two-Point Setting
Units: A
Sensor Output (Input 1): 1.23 [V]→(Scale 1): 0 [A]
Sensor Output (Input 2): 5.78 [V]→(Scale 2): 10 [A]
(With Variable function Off)
Voltage from the sensor is displayed as voltage.
It is displayed with the vertical axis (voltage axis) range and at the zero
position set on the Channel settings window ( [Analog] sheet).
The Variable function is set as follows:
Variable: On, Set Upper/Lower Limits
Lower Limit: 0 [A] Upper Limit: 10 [A]
The full span of output from the sensor is displayed.
