Stability, simplicity, and performance by design
The 8588A incorporates exceptional linearity, low noise, and stability in the design. This best-in-class long-scale digital reference multimeter guarantees superior 3.5 ppm one-year dc voltage relative accuracy and long-term stability over a wide measurement range and functions.
The 8588A contains the world’s most stable voltage references and attenuators custom-crafted at Fluke Calibration. These precision components eliminate the need for daily internal self-calibration to compensate for drift when less-precise components are used. Autozeroing also becomes unnecessary because the amplifier offsets are ultra-stable. The 8588A achieves an exceptional 8.5-digit resolution reading in one second, two times shorter than the next best in class, which amounts to considerable productivity improvements.
The 8588A is easy and intuitive to use. It is the ideal lab multimeter for metrologists and calibration laboratory managers who expect and appreciate a straightforward setup that quickly achieves the maximum performance of the instrument.
- 2.7 µV/V (95%), 3.5 µV/V (99%), 1-year relative accuracy, dc voltage without internal self-calibration or auto-adjustments
- 0.5 µV/V (95%), 0.65 µV/V (99%), 24 hour stability, dc voltage
- 7 µΩ/Ω (95%), 9 µΩ/Ω (99%), 1 year, resistance
- 2.02x full scale stretches lower noise floor to higher signal levels to maximize higher accuracies from the instrument
- 200 ns to 100 s aperture setting allows the industry’s widest flexibility to control data capture window
Accuracy, offset and stability provide excellent ac performance
The 8588A provides the most accurate true ac RMS measurement available in a Fluke Calibration multimeter.
With a 5 mega-samples-per-second sampling analog-to-digital converter and an extraordinarily stable dc analog path, the 8588A achieves remarkable ac RMS measurement performance that is ten times faster, two times less noisy, and more sensitive for low-level signals than other instruments in this class. It utilizes digital RMS calculations to maintain the full resolution of a wide dynamic range of digitized signals, so you can see a wide range of measurements clearly.
Rapid digital filters are more effective than their analog equivalents for faster settling. The digital filters eliminate the dielectric absorption on analog filters, commonly associated with residual slow-tail characteristics. The digital filters effectively shorten settling time to within 6 cycles of the filter frequency and less than 1 ppm of the fully settled value. This is up to 10 times faster than other long scale precision digital multimeters at low frequencies.
Low noise is achieved from averaging the collected high-resolution digitized data and the inherently stable signal path. De-coupling low-level signal sensitivity from temperature drift enables the 8588A to make higher accuracy low-level ac measurements. Therefore, temperature drift, offsets, and long-term instability typically associated with an analog RMS converter are eliminated.
- 60 µV/V (95%), 77 µV/V (99%), 1-year relative accuracy, for the most accurate ac voltage measurement
- 250 µA/A (95%), 323 µA/A (99%), 1-year relative accuracy, ac current
- 15 ms settling time at 1kHz ac filter form 10x faster ac voltage measurement
- 2.02x full-scale Vpp, 1.2x full-scale rms
- Up to 30 A for peak ac current greatly extends ac current measurement range
The MET/CAL™ Calibration Management Software advantage
The 8588A and 8558A work with Fluke Calibration MET/CAL™ Calibration Software with native MET/CAL support or using 8508A emulation mode to increase throughput up to four times that of traditional manual and multi-product methods while ensuring calibrations are performed consistently every time. This powerful software documents calibration procedures, processes and results for ease in complying with ISO/IEC 17025 and similar quality standards.
