Turn ON/OFF the channel
Section 5.1
Variable/Position
Sections 5.4 and 5.9
Turn Variable ON to set the upper and lower limits
of the vertical axis according to the displayed
waveform and zoom or expand the waveform
vertically. When Variable is turned OFF, the
vertical position of the waveform can be specified.
FV setting
Section 5.19
Select the function from nine measurement
parameters. For each measurement parameter
that is selected, set the smoothing filter, pulse
average, deceleration/stop prediction, and so on.
Value/Div
Section 5.19
Set the value per division along the vertical axis.
The selectable range and unit vary depending on
the measurement parameter. You can also set
the value using the V/DIV knob.
Input setting
Section 5.19
Enter settings related to the input such as the
voltage range, input coupling, probe type,
bandwidth limit, threshold level, hysteresis,
slope, chatter elimination function ON/OFF, and
pull-up ON/OFF. When you select a preset, the
input is set to values appropriate for the signal.
Vertical Zoom/Expand and Offset
Sections 5.8 and 5.10
Set the magnification and display range when
waveforms are zoomed/expanded vertically and
the offset voltage.
Note
Turn ON/OFF linear scaling
Section 5.11
Set the method of scaling the measured values.
Select OFF when not scaling.
Waveform label
Section 8.10
You can arbitrary set the waveform label using
up to eight characters.

Measurement Parameters of the Frequency Module
The following nine parameters can be measured on the
frequency module.
• Frequenc y [Hz]
• Re volution [rpm]
• Re volution [rps]
• Period [s]
• Power Freq.: Power supply frequency [Hz]
• Duty: Duty cycle [%]
• Pulse Width [s]
• Pulse Integration (distance and flow rate)
• Velocity [km/h, m/s]
Note
Deceleration Prediction
Automatically predicts the deceleration from the elapsed
time (
∆
t) after the pulse input stops. The deceleration
prediction starts after a pulse period (T) of the pulse one
period before the pulse input stopped elapses after the
pulse input stopped.
Stop Prediction
The function determines the stop point at a constant
time after the pulse input stops, and the frequency is set
to 0. Set the time (T
×
n) by specifying
×
n (where n =
1.5 to 10) of the pulse period (T) of the pulse one period
before the pulse input stopped.
• The figure below shows the menu of the channel in which the frequency module (701280 (FREQ)) is installed.
