5.10 Setting the Offset Value
Explanation
The offset value is valid when measuring voltage, or frequency and other parameters on
the frequency module.
Selectable Range of Offset Value
When measuring voltage:
±
5 div
On the frequency module, the range varies depending on the measured parameter.
• When measuring the frequency:
±
(Value/div value)
×
1000 or 200 kHz
• When measuring RPMs:
±
(Value/div value)
×
1000 or 50 krpm
• When measuring RPSs:
±
(Value/div value)
×
1000 or 1000 rps
• When measuring the period:
±
(Value/div value)
×
1000 or 50 s
• When measuring the duty cycle:
±
(Value/div value)
×
1000 or 100%
• When measuring the pulse width:
±
(Value/div value)
×
1000 or 50 s
• When measuring the pulse integration:
±
(Value/div value)
×
1000 or 1.0000E+22
• When measuring the velocity:
±
(Value/div value)
×
1000 or 1.0000E+22
Resetting the Offset Value
Pressing RESET resets the offset value to 0.
Notes When Setting the Offset Value
• When measuring voltage, the offset voltage is effective even when the acquisition is
stopped. When measuring frequency and other parameters on the frequency module,
the changes you make on the offset value are invalid when the acquisition is stopped.
The new offset value takes effect on the next measurement.
• If you change the probe attenuation when measuring voltage, the offset changes
proportionally to reflect the new attenuation rate.
• When measuring voltage, changing the voltage sensitivity does not change the offset
value. If the change would cause the offset to go outside the range, the offset moves
to the nearest range limit at the current voltage sensitivity. If you then return to the
original sensitivity, the offset returns to its original setting as well (provided that you
have not explicitly changed the value in the meantime).
Note
Changing the offset voltage allows the waveform position to be changed with respect to the
vertical position. (The center for the vertical zoom can be changed.)
