Configuring the Input Channel Settings
(1) Tap the [Coupling] box, and then choose a coupling method for an input signal from the
list.
In general, use the DC coupling.
DC  Measures both DC and AC components of an input signal.
AC Measures an AC component only of an input signal. A DC component can be
eliminated.
GND Connects the input terminal to the ground (which allows you to check the zero
position).
(2) Tap the [L.P.F] box, and then choose a cutoff frequency of the low-pass filter from the list.
Enabling the low-pass filter installed in the module can eliminate unwanted high-frequency components.
Cutoff frequencies available vary depending on the module types. Choose an adequate cutoff frequency
depending on the characteristics of an input signal.
Example: Model 8966 Analog Unit

(3) Tap the [Probe ratio] box, and then choose a probe ratio from the list.
Choose any of the ratios when the measurement involves use of a connection cord or probe.
1:1  Choose this ratio when using Model L9197, Model L9198, Model L9790, or Model
L9217 Connection Cord.
1:10
Choose this ratio when using Model 9665 10:1 Probe.
1:100 Choose this ratio when using Model 9666 100:1 Probe, Model P9000-01 Differential
Probe, or Model P9000-02 Differential Probe.
1:1000
Select this ratio when using Model 9322 Differential Probe, Model P9000-01 Differential
Probe, or Model P9000-02 Differential Probe.

Tap the [Display] button to set it to [On] or [Off] .
On  Displays the waveform on the waveform screen.
Color
Allows you to choose a display waveform of each waveform. You can also
select the same color as other lines.

When the signs of displayed waveforms are reversed, the waveforms can be
inverted.
See “3.5 Inverting a Waveform (Invert Function)” (p. 63).
Vernier Allows you to freely fine-adjust the input voltage on the waveform screen
(display adjustment only). When recording physical values such as noise,
temperature, and acceleration with sensors, you can adjust those amplitudes,
facilitating calibration.
See “3.4 Fine-Adjusting Input Values (Vernier Function)” (p. 62).
Off Does not display any waveform.

Configure the scaling settings.
See “3.2 Converting Input Values (Scaling Function)” (p. 54).
