9.2. Four Channel Voltage Module (RA30-102)
9.2.1. Overview
This four channel voltage input module samples a DC to 100 kHz signal at 16-bit 1 MS/s within the
measurement range of ±1 V to ±200 V and can perform A/D conversion. It includes an analog filter for
waveform observation. It is insulated between each channel and between input and output.
9.2.2. Setup the Input Channel
<This section describes the setting switches and setting values of the RA3100 main unit. >
(1) Slot number, input module type
(2) Change slot:
You can change the display slot by swiping this
sub menu left or right or tapping the left <
and right > key.
(3) Select channel:
Tap CH1 to CH4 in the slots and select
the channel to set.
(4) Meas. ON/OFF
ON: Measure and record the input signal.
(5) Color: Change the display color of the waveform
monitor.
(6) Coupling: Switch the input signal coupling in the order DC
→ GND. Tap the key and turn the rotary knob to
select.
(7) Meas. range:
Change the measurement range of the input
channel.
When this key is tapped, the rotary knob is
enabled (the LED lights up) and the range can
be selected by turning the knob.

(8) L.P.F.: Change the low-pass filter of the input channel.
When this key is tapped, the rotary knob is enabled (the LED lights up) and the filter can be
selected by turning the knob.
(10) Disp. pos.: Specify the position of the waveform monitor to display the specified range of the waveform
display area. Specified as a percentage indicating the center position of the display range
from the bottom of the monitor when the full range of the monitor is 100%.
(11) Disp. range: Specifies the display width in the amplitude direction of the waveform display area on the
waveform monitor. Specified (by tapping the key and turning the knob) as the percentage
of the display width when the full range of the monitor is 100%.
(12) Disp. min: Set (by tapping the key and turning the knob) the display lower limit value (scale value) of
the bottom of the display range.
(13) Disp. max: Set (by tapping the key and turning the knob) the display upper limit value (scale value) of
the top of the display range.
