The Fluke 5700A is designed to cover the widest portion of
today's calibration workload - a wide variety of DMMs from
all manufacturers. It delivers direct voltage to 1100V and
alternating voltage from 220 μν to 1100V at frequencies from
10 Hz to 1.2 MHz. Cardinal point resistances range from 1£1
to 100 ΜΩ in x1 and x1.9 decades, including a short. Direct
and alternating current are provided to 2.2A, and
frequencies for alternating current range from 10 Hz to 10 kHz.
One option is offered, wideband voltage (-03). It provides
flat, low-noise alternating voltage output from 10 Hz to 30
MHz to extend workload coverage to include RF voltmeters.
Output may be selected in volts or dBm referenced to 50Ω.
The companion 5725A Amplifier extends the 5700A's workload
coverage still further. It increases maximum direct and
alternating current to 11A for calibrating the high current
ranges of popular low-cost and hand-held DMMs. And it
extends the calibrator’s alternating volt-hertz product to
1100V at 30 kHz and 750V at 100 kHz to cover the calibration
requirements of high-accu- racy bench and system meters.
The 5700A is designed to be taken to the workload. In
manufacturing applications, test instruments may be
calibrated on-site, minimizing production line downtime due
to calibration recall.
Low Cost of Ownership
The original purchase price is not the most significant cost
associated with owning a high accuracy Calibrator. Once the
instrument is on the job, a wide range of calibration,
maintenance, repair and training requirements increase its
cost of ownership beyond the original purchase price many
The 5700A Calibrator was designed to keep those traditional
ownership costs down. Its powerful features are easy to use.
Advanced internal metrology dramatically reduces support
requirements while increasing your confidence in the
instrument’s performance. And its rugged,
modular design increases reliability and makes problems easy
to find and repair when they occur.
Simplified Calibration Support
Only three Artifact Standards, a 10V dc reference and 1Ω and
10 kQ resistance references, are required to calibrate all
5700A ranges and functions to full specifications. The
process, running under the control of the calibrator, takes
about one hour. Instructions are displayed on the front
panel in plain English to prompt the operator when to make
various connections and inputs. For added confidence, Fluke
recommends that a full verification of the 5700A be
performed every two years or as required by your established
The 5700A does not need to be recalled to the standards
laboratory for calibration. Due to its unique,
environmentally tolerant design, the 5700A may be calibrated
wherever it is used, at any temperature between 15°C and
35°C. Full performance is available for ±5°C of that
Between Artifact Calibrations, the 5700A’s performance may
be checked against its internal standards. Without adjusting
the instrument, an automated procedure is available to check
each range and function against internal check standards to
increase your confidence that it is within performance
tolerances. Should any range be shown to be out of
specification, the operator is alerted. All results of this
Cal Check process can be printed via RS-232 port. This data
can be used to develop control charts to predict the
long-term performance of the Calibrator.
High Performance That’s Easy to Use
In the past, calibration of precision DMMs required a host
of complex, manually operated instruments and standards.
The 5700A combines the functions of these instruments to
dramatically simplify DMM calibration. Values are entered on
the simple numeric keyboard and displayed on the front panel.
