The 8588A Reference Multimeter is the world’s most stable digitizing multimeter.
Designed for calibration laboratories, this long-scale high-precision reference features superior accuracy and long-term stability over a wide measurement range, with an intuitive user interface and a color display.
The 8588A delivers reliable and reproducible measurements with exceptional performance suitable for primary level laboratories.
With more than 12 measurement functions, including the new digitize voltage, digitize current, capacitance, RF power, and external shunts for dc and ac current, the 8588A helps you consolidate your lab’s cost of test into a single measurement instrument.
Its superb analog performance is augmented by Fluke Calibration’s new high-speed system design and the industry’s fastest direct digitizing capability, enabling significant throughput increase for many automated systems demanding a combination of the highest speed and best accuracy.
The 8588A holds industry’s best one-year dc voltage accuracy of 2.7 uV/V at 95 % confidence interval, or 3.5 uV /V at 99 %, and best 24-hour stability of 0.5 uV/V (95 %) or 0.65 uV/V (99 %), enabling it to outperform other long-scale reference multimeters on the market.
The 8588A further pushes the speed envelope by producing a stable 8.5 digits reading in a mere one second.
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.
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 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.
