Note (1) Always use the default setting (OFF) for pin 7.
(2) Always set pin 8 to ON if the DIP switch is used to set the ranges. If this
pin is OFF, the DIP switch settings will not be enabled.
(3) The DIP switch settings are read when power is turned ON.

Input CH0/CH1 range (common)
■
Input CH2/CH3 range (common)
Note (1) When the DIP switch is used to set the input ranges (pin 8 ON), the input
signal ranges must always be the same for Inputs CH0 and CH1 and for
Inputs CH2 and CH3. If it is necessary to set separate input signal ranges
for Inputs CH0 to CH3, use the CX-Integrator rather than the DIP switch
to make the settings.
(2) Do not set the DIP switches or pins other than as specified in the table
above.
