(1) Click the [ Coupling] box, and then choose a coupling method for an input signal from the
list.
Choose a coupling method for an input signal. 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) (1) Click 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.
The filters available vary depending on the module types. Use an adequate filter in accordance with the
characteristics of an input signal.
Example: Model 8966 Analog Unit
OFF  , 5 Hz , 50 Hz , 500 Hz , 5 kHz , 50 kHz , 500 kHz
(3) Click 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 Choose this ratio when using Model 9322, Model P9000-01, or Model P9000-02
Differential Probe.
