The 2001 and 2002 offer measurement technology which makes them attractive options to higher-priced, high-end digital multimeters. Other 7½ or 8½ digit DMMs may average multiple readings to extend their resolution. The resolution specifications of the 2001 and 2002 are based on a 28-bit A/D converter that provides the resolution needed to discern smaller changes. The higher resolution provides greater dynamic range, enabling measurement from 1µV to 20V on a single range and avoiding range-shift errors and delays.
True 7½ (2001) or 8½ (2002) digit resolution. Measurement integrity with high speed. High speed function and range changing. Broad range of built-in measurement functions includes in-circuit current, temperature with thermocouples or RDTs, peak spikes. Resistance measuring range 20Ω → 1GΩ. Frequency measuring range 1Hz → 15MHz. Multiple measurement display. GPIB interface. HP3458A emulation mode (2002 only)
Absolute Maximum DC Current Measurement = 100A dc
Absolute Maximum AC Current Measurement = 100A ac
Absolute Maximum Resistance Measurement = 34MOhms
Absolute Maximum DC Voltage Measurement = 600V dc
Absolute Maximum AC Voltage Measurement = 600V ac
Functions Measured = AC Current, AC Voltage, Continuity, DC Current, DC Voltage, Frequency, Resistance
Display Type = LCD
Model Number p = 2001
AC Voltage Measurement Resolution = 0.001V ac
DC Voltage Measurement Resolution = 0.1mV dc
