8.9 Magnifying and Compressing Waveforms
210
Description When setting combined use of the Scaling and Variable func-
tions
When Auto-Correction of the Variable function is enabled (On, default set-
ting) (⇒ p. 341)
The Variable function settings change according to Scaling and 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 setting 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 function in combination, voltage from a sensor can be con-
verted to the physical units of the measurement object.

Example. Set Scaling as follows:
Scaling: On, Two-Point Setting
Units: A
Sensor Output
(Input 1): 1.23 [V]
→ (Scale 1): 0 [A]
(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 voltage axis range and at the zero
position set on the Channel Settings screen.
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.
To reset the settings
Select the [Reset] button.
Settings return to their defaults.
