What is a 7 and a half digits multimeter
Optional 7.5-digit high-performance digital multimeter
The high-performance DMM is a hybrid design that integrates the Model 2010 DMM low-noise front-end with the Model 2701 high-speed design. The digital multimeter supports 13 built-in measurement functions, including: DCV, ACV, DCI, ACI, frequency, period, 2-wire ohms, 3-wire RTD, 4-wire RTD, thermocouple, thermistor, and continuity test.
It also includes numerous additional improvements and features to provide a technically superior, feature-rich DMM that differentiates it from other integrated switch/DMM solutions. Table 2 shows important improvements and characteristics.
Why choose 7.5-digit multimeter?
7.5-digit multimeters give mainframes a distinct advantage over low-end data acquisition systems and expand system capabilities to meet the needs of higher-end applications such as system or rack-level signal references. The DMM design provides high stability and high accuracy, supporting lower ohms and current ranges than typical 6½-digit DMMs.
An important application for mainframes is use with the 2600 Series SourceMeter Instruments (in many cases, using multiple SourceMeter instruments), which requires simple, low-cost reference standards to check and verify each SMU. A digital multimeter in the mainframe can provide this capability.
System advantages of owning a benchmark-grade 7.5-digit multimeter include:
• High stability and high precision, used to calibrate and monitor other support system equipment and instruments,
• High sensitivity ohmic test for preventive monitoring of relays and interconnects,
• All this for less than the price of a typical 6½-digit multimeter!
