- Simulates and measures all ANSI
thermocouples, as well as L and U types, and provides cold junction compensation to enable
calibration of a wide variety of thermocouple instrumentation.
- Direct input for storage of ITS-90 RTD
constants for highly accurate simulation and measurement of RTD probes.
- Direct measurement of all Fluke 700 Series
and model 525-P pressure modules covering the most common pressure ranges from 0-1” H20 to 0-10,000 PSI.
- Converts easily to any pressure unit
directly from the front panel or through remote communications.
- Sources dc voltage and current for
multifunction workload coverage, enabling calibration of data loggers, strip chart
recorders, multimeters, and other industrial instruments.
- Supports automation using Fluke’s
MET/CALŪ Plus Calibration Management Software or custom automated programs with
standard RS-232-C or optional GPIB interface.
- Eight user programmable setpoints allow
quick recall of values for Zero, Span and linearity checks during calibration.
- Programmable setpoint dwell times for
automated calibration and troubleshooting.
- Selectable internal or external CJC (cold
junction compensation) provides you with the ability to make exacting thermocouple
measurements using remote junctions.
- Easy five-way binding posts for low-loss
convenient hookup. Banana plug, screw terminal, spade lug, wraparound terminal, wire
pass-through terminal.
- NIST-traceable calibration with data is
included.

At home in the cal lab
The 525A is a compact bench instrument well suited for traditional calibration
laboratories with a large temperature workload. Its 0-100V output and 0-100 mA current
capabilities – plus its ability to serve as a highly-accurate pressure standard
– make it a versatile performer.
Filling the gap in the instrument shop
In process plant environments, instrument shop technicians responsible for maintaining the
equipment pool need to calibrate and repair a wide range of instruments, transmitters,
field calibrators, P/I converters, transducers, and temperature probes. With its ability
to simulate almost any temperature sensor, precise pressure monitoring capability, and dc
voltage and current accuracy rivaling any calibrator in its price range, the 525A fills
the gap between lower accuracy handheld field calibrators and more expensive high-end
multifunction calibrators.
A good fit for ATE test applications
With precise calibration-grade instrument control enabled via an IEEE bus, the 525A is a
hard working addition to automated test systems in quality and manufacturing test
applications requiring capabilities such as voltage and current sourcing, sensor
simulation, and temperature monitoring and validation.
Powerful functionality that is easy to use
From start to finish, the 525A is designed for ease of operation. The intuitive front
panel design features large keypads and display that help reduce training time and make
the 525A comfortable to use even for long periods of time. Plus, you can store frequently
used constants for a variety of probes in memory for faster setup on the job.
MET/CALŪ Plus automates 525A calibration and documentation management
You can use the 525A with Fluke’s MET/CAL Plus Calibration Software (v 6.11 or
later) to meet the stringent documentation and reporting requirements imposed by quality
standards such as ISO 9000. MET/CAL Plus is a powerful software environment for
creating, editing, testing, and documenting calibration procedures, and for performing
automated calibrations.
Pressure modules
An optional set of external pressure modules provides pressure measurement capability. The
525A can accept either the Fluke 700 Series pressure
modules or the Fluke Model 525A-P series pressure modules. These modules plug directly
into the calibrator’s front panel Lemo connector; the 525A firmware auto-detects the
type and value of the attached module
