CHAPTER 2 Checks and Preparation
(6) Setting the DIP switch.
Depending on the input method, set the switch (See Table below).
The settings of DIP switch are shown in the Table below. For the numbers in the
Table, 0 (zero) is OFF and 1 is ON.
Input method
Strain input
Strain sensor input
Voltage input/Resistance input
The settings of DIP switch are displayed on the menu in the main module. The DIP switch should be set depending
on the input method.
•
When the strain gauge is used
When the strain is input, set the DIP switch to "bridge circuit".
Always set depending on the strain gauge resistor.
* See the descriptions of the strain gauge and bridge circuit configuration to set the DIP switch.
•
When the strain sensor is used
When the strain sensor is used, the settings are different in 4 wires and 6 wires.

When the Voltage/Resistance input is used
In this case, set the DIP switch as shown in the figure below regardless of the strain input.
