The Ability of the DI-245 to Reject Common Mode Voltage

Data Acquisition > Thermocouple > DI-245 The ability of the DI-245 to reject common mode voltage is unmatched in the $75 per channel price range. To demonstrate the ability of the DI-245 to reject common mode (error) voltage, we connected K-type thermocouples to channels 1 and 2. With the thermocouple on channel 2 grounded, we Read More
