Fluke 7526A User Manual

7526A Precision
Process Calibrator

Calibrate temperature,
pressure, and low dc voltage
process tools in a single
benchtop instrument

The 7526A Precision Process Calibrator
calibrates a wide range of pressure gauges,
temperature transmitters, digital process
simulators, multimeters and more.

Versatility, precision and value

—

all combined into a single
benchtop process calibration tool

The Fluke Calibration 7526A Precision Process Calibrator offers the best balance of economy
and accuracy for benchtop calibration of pressure and temperature process instrumentation.
Incorporating an isolated measurement channel, the 7526A lets you simultaneously source
and measure voltage, current or resistance, making it easy to calibrate temperature and pressure
transmitters, RTD and thermocouple readouts, pressure gauges, digital process simulators, data
loggers, multimeters and more.

• Sources and measures dc voltage, current, resistance, RTDs and thermocouples

• Measures pressure using Fluke 700 Pressure Modules

• Measures 4-20 mA loop current

• Sources 24 V dc transmitter loop power supply

• Tests pressure and thermal switches with an automated switch-test function

• Measures thermistors up to 4 kΩ

• Stores up to nine programmable setpoints for each input/output parameter

• Accepts ITS-90 coefficients for accurate SPRT measurements

• Compatible with MET/CAL

A “best fit” for your process calibration requirements

“Doing more with less” is a requirement every process manufacturer faces today. To maintain
product quality, reduce waste, improve efficiency and conform to regulatory standards, instruments
that measure process variables such as temperature and pressure must be calibrated at regular
intervals. Selecting the right calibrator for the job, however, can be tricky—especially when
attempting to balance precision and versatility with cost. Less expensive than high-end
multi-product calibrators, yet more precise
and versatile than handheld field
calibrators, the 7526A is a “best
fit” for instrument shops that
value precision, versatility
and economy.

Everything you
need in one box

The 7526A packs a lot of capability
into one box, allowing you to calibrate a
wide-ranging and varied workload. One
calibrator performs all of these functions:

• Simulates and measures nine RTD and
thirteen thermocouple types

• Accurately measures pressure up to 10 000
PSI (69 MPa) when combined with Fluke 700
Pressure Modules

• Sources and measures dc voltage to within

0.004 % of reading

• Sources and measures dc resistance up to 4 kΩ

• Sources dc current from 0 mA to 100 mA

• Accurately measures dc current from 0 mA to 50 mA

• Sources 24 V dc loop power

Intuitive user interface

The user interface includes cursor controls, function keys and a ten-key keypad, making it easy
to navigate through intuitive menus; store and recall up to nine setpoints for each input/output
parameter; enter RTD or SPRT coefficients; and easily change display units with a key press.
With two LCD displays, you can easily view both source and measurement results simultaneously.

DC voltage output terminals. 0 mV to 100 V.
Accuracy: 30 ppm (+3 µV), 1 year*. Five-way beryllium­copper binding posts reduce thermal EMFs and accept
common cable terminations (standard single/dual pin
banana plug, spade lug, pin connector, bare wire).

DC current output terminals. 0 mA to 100 mA.
Accuracy: 50 ppm, 1 year

RTD/Ω output terminals (two-wire). 5 Ω to 4 kΩ.
Accuracy: ± 0.05 °C*. Accepts Pt-100 (385, 3926,

3916), Pt-200, Pt-500, Pt-1000, Ni-120, Cu-427, SPRT.

Thermocouple input/output terminal. Accuracy: ± 0.1 °C *.
User selectable internal or external cold junction compensation
for improved thermocouple measurement accuracy. Accepts
thermocouple types: B,C,E,J,K,L,N,R,S,T,U,XK,BP

Isolated input terminals for dc voltage/
current measurement, unique switch-test
input for testing pressure and thermal
switches, and a 24 V dc loop power supply
for powering 4-20 mA transmitters.

Four-wire RTD/Ω input terminals.
Accuracy: ± 0.02 °C*. Accepts Pt-100
(385, 3926, 3916), Pt-200, Pt-500,
Pt-1000, Ni-120, Cu-427, SPRT.

Isolated pressure module input. Connect a Fluke
700 Pressure Module to the front panel LEMO
connector and the calibrator auto-detects the type
and value of the module.

Isolated input controls. A HART key enables
a 250 Ω loop resistor allowing HART devices
to read a digital HART signal superimposed
on the 4-20 mA loop current.

* See extended specifications

for more details.

Don’t forget the sensor

Calibrating the electronics portion of a temperature transmitter
is only a part of a complete calibration. You also need to
calibrate the temperature sensor itself, whether an RTD or
thermocouple. Ignoring the sensor can be a mistake, because
temperature sensors are responsible for more than 75 % of the
output errors in temperature transmitters. You can calibrate the
temperature sensor individually, or calibrate both the sensor and
the transmitter as a system using a dry-block calibrator such
as the Fluke Calibration 914X Series Field Metrology Wells. The
Field Metrology Wells were designed specifically with process
calibration in mind—optimizing speed to temperature, portability,
stability and accuracy. The 7526A and a 914X dry-block calibrator
make a perfect combination for calibrating just about any
temperature transmitter.

Source as well as measure pressure

The P5500 Series Comparison Test Pumps can be used with the 7526A and Fluke 700 Series
Pressure Modules to generate or control test pressures. The unique test port configuration
allows for easy, tool-free connections of a wide variety of connection sizes and types, includ­ing NPT, BSP, and metric threads. The P5510 includes a built-in hand pump to generate vacuum
or positive pressure up to 300 psi (2 MPa). The P5513 allows for precise control of pneumatic
pressures up to 3000 psi (20 MPa). An external pressure supply is required. The P5514 allows
for generation of hydraulic pressures up to 10 000 psi (70 MPa). The P5515 includes a built-in
priming pump and screw pump that allows for pressure
generation up to 20 000 psi (140 MPa). Both the P5514
and P5515 can be used with oil or water. Special
versions are available with ethylene
propylene seals
for use with more
aggressive fluids.
