DIP Switches
The 8 DIP switches (shown in Figure 10) are used with the 8 universal inputs ONLY when the
inputs are connected to resistive 1000 Ω temperature sensors.
In all other cases, make sure that the DIP switches are off.
For example, if you are going to connect universal input 1 to a resistive 1000 Ω temperature
sensor, turn on DIP switch 1.
The DIP switches are set at the factory in the off position.
