DIGITAL MULTIMETERS
2000 Series Scanners
Keithley has designed three plug-in scanner cards for use with Model 2000, 2001, 2002, and 2010
DMMs. Simply by inserting the appropriate card in the option slot on the DMM’s back panel, users
can create a multipoint test and measurement system that’s well suited to applications involving up
to ten measurement points. Combining scan and measurement capabilities in a single instrument
reduces the need for extra equipment, eliminates complexities of triggering, timing, and processing
issues, and helps reduce test time significantly. Also, since the scanners were designed specifically
to work with these DMMs, measurement integrity is assured. For larger ATE applications, the DMMs
can be easily combined with Keithley’s 7000 Series switch matrices and cards for high-speed, highaccuracy scanning and measurement.
Model 2000-SCAN
Model 2001-SCAN
Model 2000-SCAN Scanner Card
• Ten analog input channels (2-pole)
• Configurable as 4-pole, 5-channel
Model 2000, 2001, 2002, and 2010 DMM users can create
an economical ten-channel data logger simply by inserting the Model 2000-SCAN scanner card into the DMM’s
back panel option slot. Users can multiplex one of ten 2pole or one of five 4-pole signals into the Model 2000
and/or any combination of 2- or 4-pole signals. Contact
potential is typically less than 500nV per contact pair (1µV
maximum) for high measurement integrity.
Model 2001-SCAN Scanner Card
• Ten analog input channels
• Two channels of 2-pole high-speed solid-state switching
• High-speed ratio and delta measurements

this 20-channel scanner
card, used with the 2000-20
DMM.
These products are available with an
Extended Warranty. See page 635 for complete ordering information.
The 2001-SCAN is a high-speed multiplexing generalpurpose scanner card for use with the 2000, 2001, 2002, or
2010 multimeter. Installing the 2001-SCAN card into the meter transforms it into a high-accuracy,
high-speed ten-channel data logger for a wide variety of mixed-signal applications. The card’s
500nV–125V signal range makes it well suited for both low and high level signals. Two high-speed
solid-state channels make it possible to calculate ratio and delta when used with the 2001, 2002,
or 2010.

Model 2001-TCSCAN Thermocouple Scanner Card
• Nine analog input channels
• Scan up to 43 channels per second
• Built-in temperature reference for thermocouple cold-junction compensation
• Suitable for general-purpose measurements of voltage, resistance, and frequency
• 500nV–125V signal range
When installed in a 2000, 2001, 2002, or 2010 DMM, the Model 2001-TCSCAN provides up to nine
channels of cold-junction compensated temperature measurements and/or voltage, resistance, and
frequency measurements. When the card is installed in the 2001 or 2002, the DMM will linearize
type J, K, E, R, S, B, and T thermocouples automatically. The Model 2000 DMM provides built-in
support for J, K, and T-type thermocouples. The Model 2010 has built-in support for J, K, T, and N
thermocouples. Readings are output directly in the user’s choice of Celsius, Fahrenheit, or Kelvin
scales. Total system accuracy is 0.65°C (with Type J TCs). When used with the 2001, 2002, or 2010, the
2001-TCSCAN can also measure temperature directly using 2- or 4-wire RTDs.
