Using the SCB-68 with MIO DAQ Devices
You can take measurements with the SCB-68 and multifunction I/O (MIO)
DAQ devices, such as E/M/S Series devices, in a number of ways. Switches
S1 and S2 provide power to the signal conditioning area of the accessory.
The SCB-68 has a temperature sensor for cold-junction compensation (CJC)
to accommodate thermocouples; switches S3, S4, and S5 configure the
temperature sensor for different analog input settings. Table 2 shows the
different switch settings for MIO DAQ devices.
