Introduction
The 2001-TCSCAN scanner card is designed for use in a digital multimeter (DMM) to make accurate,
multi-channel thermocouple measurements. The 2001-TCSCAN can also be used for multiple
nine-channel, mixed-signal switching applications. The 500 nV - 125 V signal voltage range allows for
both low and high signal levels.
If you are using this scanner card with the 2700, 2701, or 2750, please see the Model 2001
scanner card Instruction Manual.
Features
The 2001-TCSCAN is a scanner card designed to be installed in the DMM6500 6½ Digit Graphical
Sampling Multimeter. Features of the card 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
• The capability to multiplex one of nine 2-pole or one of four 4-pole channels into the DMM
Unpacking and inspection
Inspecting for damage
The 2001-TCSCAN is packaged in a resealable, anti-static bag to protect from damage due to static
discharge and contamination that could degrade its performance. Before removing the card from the
bag, observe the following handling precautions.
