Document number: SPEC-2001L
Specifications are subject to change without notice.
Introduction
The following pages contain the complete specifications for the Model 2001. Every effort has been made to make these specifications complete by characterizing its performance under the variety of conditions often encountered in production, engineering, and research.
The 2001 provides 5-minute, 1-hour, 24-hour, 90-day, 1-year, and 2-year specifications, with full specifications for the 90-day, 1-year, and 2-year specifications. This allows the user to utilize 90-day, 1-year, or 2-year recommended calibration intervals, depending upon the level of accuracy desired. As a general rule, the 2-year performance of the Model 2001 exceeds a 5½-digit DMM's 90-day, 180-day, or 1-year specifications. 6½- or 7½-digit performance is assured using 90-day or 1-year specifications.
ABSOLUTE ACCURACY
Based on factory calibration, all 90-day, 1-year, and 2-year specifications are absolute accuracy, traceable to the International System of Units (SI) through a National Metrology Institute (NMI).
TYPICAL ACCURACIES
Accuracy can be specified as typical or warranted. All specifications shown are warranted unless specifically noted. Almost 99% of the 2001's specifications are warranted specifications. In some cases, it is not possible to obtain sources to maintain traceability on the performance of every unit in production on some measurements (for example, high-voltage, high frequency signal sources with sufficient accuracy do not exist). Since these values cannot be verified in production, the values are listed as typical.

4 Specifications are for 1 power line cycle, Auto Zero on, 10-reading digital filter, except as noted.
5 DCV Transfer Stability typical applications are standard cell comparisons and relative accuracy measurements. Specs apply for 10 power line cycles, 20-reading digital filter, autozero on with type synchronous, fixed range following 2-hour warm-up at full scale to 10% of full scale, at TREF ±1 °C (TREF is the initial ambient temperature). Specifications on the 1000 V range are for measurements within 5% of the initial measurement value and following measurement settling.
6 For TCAL ±1 °C, following 55-minute warm-up. TCAL is ambient temperature at calibration, which is 23 °C from factory.
7 For TCAL ±5 °C, following 55-minute warm-up.
8 When properly zeroed using REL function.
DC VOLTAGE UNCERTAINTY = ± [(ppm of reading) × (measured value) + (ppm of range) × (range used)] / 1,000,000.
% ACCURACY = (ppm or accuracy) /10,000.
1PPM OF RANGE = 2 counts for ranges up to 200V, 1 count on 1000V range at 6½ digits.

Effective noise is reduced by a factor of 10 for every 20 dB of noise rejection (140 dB reduces effective noise by 10,000,000:1). CMRR is rejection of undesirable AC or DC signal between LO and earth. NMRR is rejection of undesirable AC signal between HI and LO. |

SETTLING CHARACTERISTICS: <500µs to 10ppm of step size. Reading settling times are affected by source impedance and cable dielectric absorption characteristics. Add 10ppm of range for first reading after range change.

ISOLATED POLARITY REVERSAL ERROR: This is the portion of the instrument error that is seen when high and low are reversed when driven by an isolated source. This is not an additional error — it is included in the overall instrument accuracy spec. Reversal Error: <2 counts at 10V input at 6½ digits, 10 power line cycles, 10-reading digital filter.
INPUT BIAS CURRENT: <100pA at 25 °C.
LINEARITY: <1ppm of range typical, <2ppm maximum.
AUTORANGING: Autoranges up at 105% of range, down at 10% of range.
15 See Operating speed for additional detail. For DELAY=0, internal trigger, digital filter off, display off (or display in “hold” mode). Aperture is reciprocal of line frequency. These rates are for 60 Hz and (50 Hz).

DEFAULT MEASUREMENT RESOLUTION: 3½ digits.
MAXIMUM INPUT: ±1100 V peak value, 2×107 V•Hz (for inputs above 20 V).
NON-REPETITIVE SPIKES: 10% of range per µs typical slew rate.
SPIKE WIDTH: Specifications apply for spikes ≥ 1 µs.
RANGE CONTROL: In Multiple Display mode, voltage range is the same as DCV range.
SPIKES MEASUREMENT WINDOW: Default is 100ms per reading (settable from 0.1 s to 9.9 s in Primary Display mode).
INPUT CHARACTERISTICS: Same as ACV input characteristics.
SPIKES DISPLAY: Access as multiple display on DC Volts. First option presents positive peak spikes and highest spike since reset. Second option presents negative spikes and lowest spike. Highest and lowest spike can be reset by pressing DCV function button. Third option displays the maximum and minimum levels of the input signal. Spikes displays are also available through CONFIG-ACV-ACTYPE as primary displays.
16 Specifications apply for 10-reading digital filter. If no filter is used, add 0.25% of range typical uncertainty.
17 Specifications assume AC+DC coupling for frequencies below 200Hz. Below 20Hz, add 0.1% of reading additional uncertainty.
18 Add 0.001% of reading × (VIN/100V)2 additional uncertainty for inputs above 100V.

RESISTANCE UNCERTAINTY: = ±[ (ppm of reading) × (measured value) + (ppm of range) × (range used) ] / 1,000,000.
% ACCURACY: = (ppm accuracy) / 10,000.
1PPM OF RANGE: = 2 counts for ranges up to 200MΩ and 1 count on 1GΩ range at 6½ digits.
28 When measuring resistance of inductive loads, the inductance of that load must be 10mH or less.
29 Current source is typically ±9% of absolute accuracy.
30 Total of the measured value and lead resistance cannot exceed full scale.
31 Maximum offset compensation plus source current times measured resistance must be less than source current times resistance selected.
32 Specifications are for 1 power line cycle, 10 reading digital filter, Auto Zero on, 4-wire mode, offset compensation on (for 20Ω to 20kΩ ranges).

SETTLING CHARACTERISTICS: For first reading following step change, add the total 90-day measurement error for the present range. Pre-programmed settling delay times are for <200 pF external circuit capacitance. For 200 MΩ and 1 GΩ ranges, add total 1 year errors for first reading following step change. Reading settling times are affected by source impedance and cable dielectric absorption characteristics.
OHMS MEASUREMENT METHOD: Constant current.
OFFSET COMPENSATION: Available on 20 Ω to 20 kΩ ranges.
OHMS VOLTAGE DROP MEASUREMENT: Available as a multiple display.
AUTORANGING: Autoranges up at 105% of range, down at 10% of range.
360 For TCAL ±5 °C, 90-day accuracy. 1-year and 2-year accuracy can be found by applying the same speed accuracy ppm changes to the 1-year or 2-year base accuracy.
37 Ohms measurements at rates lower than 1 power line cycle are subject to potential noise pickup. Care must be taken to provide adequate shielding.

45 For TCAL ±5 °C, 90-day accuracy. 1-year and 2-year accuracy can be found by applying the same speed accuracy ppm changes to the 1-year or 2-year base accuracy.
SETTLING CHARACTERISTICS: <500µs to 50ppm of step size. Reading settling times are affected by source impedance and cable dielectric absorption characteristics. Add 50ppm of range for first reading after range change.
MAXIMUM ALLOWABLE INPUT: 2.1A, 250V.

AUTORANGING: Autoranges up at 105% of range, down at 10% of range.
DC IN-CIRCUIT CURRENT
The DC in-circuit current measurement function allows a user to measure the current through a wire or a circuit board trace without breaking the circuit. When the In-Circuit Current Measurement function is selected, the 2001 will first perform a 4-wire resistance measurement, then a voltage measurement, and will display the calculated current.
TYPICAL RANGES:
Current: 100µA to 12A.
Trace Resistance: 1mΩ to 10Ω typical.
Voltage: ±200mV maximum across trace
Speed: 4 measurements/second at 1 power line cycle
Accuracy: ±(5% + 2 counts). For 1 power line cycle, Auto Zero on, 10 reading digital filter, TCAL±5 °C, after being properly zeroed. 90 days, 1 year, or 2 years.
