* NOTE: The 2000-SCAN will operate in all four models as a 10-channel scanner, but does not have the two high-speed solid
state channels required by the 2001 and 2002 Ratio and Delta modes. The 2001-SCAN will operate as a 10-channel scanner in all four models, but the 2000 and 2010 cannot utilize the two high-speed solid state channels.
** Replacement card for 2000-20 DMM/Scanner combination. See page 46 for specifications.

one of five 4-pole signals into the Model
2000, 2001, 2002, or 2010 DMM and/or any
combination of 2- or 4-pole signals. Two
solid state channels offer high-speed multiplexing on the Model 2001 and 2002. For
complete specifications, see Model 2001SCAN, page 56.

221mm deep (0.83 in × 2.83 in × 8.7 in). Adds 0.4kg
(10 oz).
ACCESSORY SUPPLIED: C109 Test Lead Set for output
connections (two red, two black).
Model 2001-TCSCAN: Provides nine channels of cold-junction compensated temperature measurements and/or voltage, resistance, and frequency measurements when
installed in a 2000, 2001, 2002, or 2010
DMM. (See specific instrument for TC types
linearized.) Also can measure temperature
directly using 2- or 4-wire RTDs (except with
Model 2000). For complete specifications,
see page 56.

INSTRUMENT ACCESSORIES
Function and Scanning Options
Model 6521 Low Current Scanner Card: A
10-channel multiplexer, designed for switching low currents in multipoint testing applications or when the test configuration must
be changed. Offset current on each channel
is <1pA and high isolation is maintained
15
between each channel (>10
Ω). The 6521
maintains the current path even when the
channel is deselected, making it a true current switch. BNC input connectors help provide shielding for sensitive measurements
and make the card compatible with low
noise coaxial cables.
For use with: 6517A Electrometer
CONTACT CONFIGURATION: Single pole, “break-
before-make” for signal HI input. Signal LO is common for all 10 channels and output. When a channel
is off, signal HI is connected to signal LO.
CONNECTOR TYPE: Inputs BNC, Outputs Triaxial.
SIGNAL LEVEL: 30V, 500mA, 10VA (resistive load).
CONTACT LIFE: >10
>107closures at low signal levels.
CONTACT RESISTANCE: <1Ω.
CONTACT POTENTIAL: <200µV.
OFFSET CURRENT: <1pA (<30fA typical at 23°C,
<60% RH).
ACTUATION TIME: 2ms.
COMMON MODE VOLTAGE: < 30V peak.
6
closures at maximum signal level;
Model 6522 Voltage/Low Current Scanner
Card: Provides up to ten channels of low-
level current, high-impedance voltage,
high-resistance, or charge signal switching.
Although it is similar to the 6521, the 6522’s
input connectors are 3-lug triax. The card
can be software configured for high-impedance voltage switching of up to 200V. Triax
connectors make it possible to float the card
500V above ground and drive guard to 200V.
For use with: 6517A Electrometer
CONTACT CONFIGURATION: Single pole, “break-
before-make” for signal HI input. Signal LO is common for all 10 channels and output. When a channel
is off, signal HI is connected to signal LO. 6517A can
also configure channels as voltage switches.
CONNECTOR TYPE: Inputs: Triaxial. Outputs: Triaxial.
SIGNAL LEVEL: 200V, 500mA, 10VA (resistive load).
CONTACT LIFE: >10
>107closures at low signal levels.
