The 2001 is a high performance, 7.5 digit, Digital multimeter with a vacuum flourescent display. It can measure DC voltage (normal and peak spikes), AC voltage (RMS, average, and peak), DC current (normal and in-circuit), AC current (RMS and average), two and four-wire resistance (normal and offset-compensated), frequency, and temperature (resistance temperature devices or thermocouples). Readings and setup data can be stored and recalled from the front panel or over the IEEE-488 bus. Internal memory is 8 kB standard with 32 kB or 128 kB available optionally. An optional, field-installable, 10 channel scanner is available for data acquisition applications.
