The Model 2001-TCSCAN General Purpose/Thermocouple Scanner Card, which is designed to be used with the Model 2000, 2001, 2002, and 2010 DMMs to make accurate multi-channel thermocouple measurements. The DMMs will automatically convert type J, K, T, E, R, S, and B thermocouple voltages to Celsius, Fahrenheit, or Kelvin temperature readings. The Model 2001-TCSCAN can also be used for a variety of nine-channel, mixed-signal switching applications. The 500nV-125V signal voltage range of the Model 2001-TCSCAN makes it well suited for both low and high signal levels. The Model 2001-TCSCAN is a scanner card designed to be installed in the Model 2000, 2001, 2002, or 2010 Multimeter. Key features include: • Built-in reference junction (channel 1). • Low contact potential and offset current. • Input connectors are in contact with an isothermal block to minimize temperature differences. • Nine channels of 2-pole relay input. • Four channel pairs configurable for 4-pole operation. • Multiplex one of nine 2-pole, or one of four 4-pole channels into the DMM.
