12.3 Defining User-defined Units
WF1967/WF1968 12-4
log is a common logarithm whose base is 10. You need to pay attention to when you use a log
formula for a value that can be negative such as the DC offset and phase. If a value before changing
to the user-defined unit is zero (0), "-Inf" is displayed when changing to the user-defined unit using
the log. Similarly, if a value before changing to the user-defined unit is negative, "Over" is
displayed when changing to the user-defined unit using the log.
Multiplier and offset of formula [m], [n]
Select the multiplier m and offset n in the selected formula.
After setting each parameter, select [OK] at the bottom of the window and press the ENTER key.
■
To set the frequency in rpm
For example, to display and set the frequency in 1 Hz as the frequency in 60 rpm, set the followings
and select [OK]:
Next, in the Oscillator screen, open the input field for the frequency, and then change the unit from Hz
to rpm.
This can display and set a value in units of rpm.
Check
When you use the user-defined unit, the setting resolution may be rough
depending on the setting of multiplier or offset.
