Description


The 2001 Series offers 7 ½ -digit resolution and basic DCV accuracy of 0.0018%, offering  exceptional resolution, accuracy, and sensitivity. This high performance digital multimeter not only delivers performance specifications usually associated only with instruments that cost thousands more, but it also offers a broad range of functions not typically available in DMMs. For greater flexibility, a built-in card slot on the rear panel allows an additional multiplexer card for multi-point measurement applications. 

2001

Features: 


- True 7-1/2 (Model 2001) or 8-1/2 digit (Model 2002) resolution
- Exceptional measurement integrity with high speed
- High speed function and range changing
- Broad range of built-in measurement functions
- Multiple measurement display
- Built-in 10 channel scanner option
- GPIB interface
- HP3458A emulation mode (Model 2002)
