The 8520A and 8522A are designed for system and bench
applications and have built-in system interface circuits.
The performance specifications of the two instruments are
almost identical. The principal difference is that the 8520A
has an interface compatible with GPIB/IEEE-488* 1978 and the
8522A has an interface suitable for either BCD or Parallel
The 8520A/AS-1 and the 8520A/PRT are unique variations of
the 8520A. One, the 8520A/ AS-1, is compatible with U.S.
Government Modular Automatic Test Equipment (MATE) system.
And the 8520A/PRT includes a Platinum Resistance Probe for
extremely accurate temperature measurements.
Seven standard and seven optional math programs plus a
built-in “burst” memory make these multimeters exceptionally
intelligent stand-alone units. A choice of dc volts,
true-rms ac volts, 2- wire or 4-wire ohms, and the Fluke
exclusive conductance function make the instruments very
versatile. The conductance function provides a simple way to
measure resistance from 10 ΜΩ to 100,000 ΜΩ.
The instruments boast 50 ppm basic dc accuracy for 90 days
with 5'/2 digit resolution. A 520 readings-per-second system
rate with ΑΊ2 digits resolution is standard for high speed
