Using the SCB-100 with MIO Devices

You can take measurements with the SCB-100 and MIO DAQ devices, such as E Series, in a
number of ways. The SCB-100 has a temperature sensor for cold-junction compensation to
accommodate thermocouples. Switches S4, S5, and S6 configure the temperature sensor for
different analog input settings. The following table shows the different switch settings for
MIO DAQ devices.
