More functions and better accuracy in one calibrator

• Three complete calibrators

Unlike any other combination thermocouple/milliamp
calibrator on the market the PIE 525Plus includes a
FULL function diagnostic milliamp calibrator that sources
and reads 0.000 to 24.000 mA, simulates two wire
transmitters, powers & measures transmitters with its
internal 24V supply, has a built-in 250 ohm resistor for
HART compatibility and PIE’s patented Ground Leak
Detection. Competitive calibrators allow you to calibrate
temperature transmitters but don’t have the ability to test
other instruments in a 4 to 20 mA loop.

The two parts of the calibrator sources and reads both
14 thermocouples types and 12 RTD types to 0.01°F &
°C.

• Protect instruments & technicians from

(potentially dangerous) catastrophic
failures due to hidden loop problems

It’s important to find hidden loop problems BEFORE
they cause product problems or catastrophic failures.
Only PIE Calibrators have Ground Leak Detection that
can detect these problems.

• State of the art accuracy & stability

It’s important to have a calibrator that is at least 4 times
more accurate than the instruments being calibrated.
The milliamp, thermocouple & RTD sections were
designed with state of the art components that are the
most accurate and stable found in a handheld calibrator.
The internal cold junction is accurate to ±0.05°C and is
traceable to NIST.

• Verify Heat Treating Uniformity Survey

Recorders & perform System Accuracy
Tests

The AMS 2750 standard calls out particular specifications
that need to be met for a calibrator to be used as a Field
Test Instrument. The Field Test Instrument is then used
to verify the thermocouple measuring thermometers and
controllers that are used in the heat treating of parts for
the aerospace industry.
The PIE 525Plus is capable of meeting the requirements
of an AMS 2750 Field Test Instrument when certified by
an accredited laboratory.

• Compatible with ALL process instruments

Calibrating smart transmitters and PLCs is a problem for
many electronic RTD calibrators. These instruments
measure RTD sensors with a pulsed excitation current
that is too fast for many calibrators to lock onto which
causes errors in calibration. The PIE 525Plus has
unique circuitry designed to accurately calibrate smart
and multivariable transmitters, PLC inputs, and
multichannel recorders. PIE guarantees compatibility

with all RTD instruments.

• Troubleshoot RTD sensors

When you have an RTD input problem that is difficult to
diagnose the PIE 525Plus makes it easy. When the
calibrator is connected directly to the RTD sensor it will
indicate on the display which wires are connected. This
quickly points out if there is problem with the wiring or
with the sensor itself. Secondary displays show you the
resistance value of the RTD plus the magnitude and
direction of the excitation current used by the instrument
to measure an RTD sensor.

• Troubleshoot Thermocouple sensors

Save costs and improve uptime by replacing
thermocouple probes as they are approaching the
failure point. Replacing them too early increases your
costs and waiting for them to fail can lead to expensive
downtime charges. The PIE 525Plus measures the
resistance of the cables and sensing element at the
same time it displays the temperature in °C or °F while
the probe is installed in the process. Probes with high
resistance should be replaced before they burn out.
Open thermocouples and thermocouples that have high
resistance indicating impending failure are indicated by
OPEN TC and the resistance value on the display.

• Half t

he size

of the closest competitor

and the easiest to use

Don’t get tired by lugging around heavy oversized test
equipment when you can carry the palm sized PIE
525Plus that weighs less than a pound. It comes with a
deluxe carrying case for simple, hands free operation.
The simple and intuitive double click menu and EZ-Check
switch are faster and easier to use than calibrator with
lots of confusing buttons or with confusing menus. And
with the optional magnet strap you can attach it to a

panel or loop the strap around a conduit or pipe.
Many calibrators don’t have automatic stepping and
ramping while others limit you to selecting either slow or
fast fixed 25% steps. The PIE 525Plus lets you choose
between 2, 3, 5, 11 and 21 steps to automatically
increment the output in 100%, 50%, 25%, 10% or 5% of
span. Select the step time to match your system from 5,
6, 7, 8, 9, 10, 15, 20, 25, 30 and 60 seconds.

Ground Leak Detection

Prevent Small Problems from Becoming Major Plant Failures

The PIE 525Plus offers powerful troubleshooting tools that offer visibility to the health of your loop that is not possible
with any calibrator brand on the market. Ground Leak Detection allows technicians to find and fix undetected
problems before they cause quality issues or become catastrophic failures - producing poor product, injury, loss of
life, or equipment damage. Common loop problems caused by moisture, corrosion and contamination left unchecked
can lead to dangerous conditions that are easily avoided with the innovation technology in the PIE 525Plus.

Even the most common small errors caused by loop wiring issues can lead to inferior product, lost production time
and risk to personnel. Intrinsically safe loops are protected by barriers only against extreme overvoltage and over
current conditions but allowing small but significant ground faults to go undetected. PIE’s unique and powerful
Ground Leak Detection technology quickly and easily finds a fault that would otherwise go undetected. These
undetected faults could lead to potentially disastrous outcomes.

Have you ever replaced a “faulty” transmitter only to find the problem was somewhere else in the loop? And did you
end up throwing the transmitter away after you fixed the other problem “just in case” the transmitter was faulty?
If you find a loop where the transmitter is calibrated correctly but all the readings elsewhere in the loop have a fixed
offset this is due to a Zero Shift. This Zero Shift is typically caused by some of the current in the loop bypassing the
transmitter. If you have some loops that are erratic after it rains there may be moisture present in a junction box or
where insulation has broken down.

Only a PIE Calibrator with patented Ground Leak Detection can find all these hidden problems. Turn on Ground Leak
Detection and use the PIE 525Plus to power up the loop. Any current that isn’t controlled by the transmitter or other
current control element will be clearly indicated as leakage on the PIE 525Plus display.

Ground Leak detection allows technicians to troubleshoot loop problems with ease and confidence - minimizing risk
and maximizing process uptime.

Troubleshooting RTD & Thermocouple Sensors

Problem found with RTD Sensor Wiring

Here is an example of the PIE 525Plus reading a
sensor with all 4 wires connected.

Only a calibrator with PIE’s patented 2, 3 & 4 wire detection makes
troubleshooting sensor wiring quick, easy and automatic. This is much
simpler and faster than going through the process of testing each pair of
wires to figure out which, if any, connection is loose or which wire is broken.

Problem found with Thermocouple Probe Resistance

Here is an example of the PIE
525Plus reading a new sensor with
low resistance. The resistance is
approximately 100 ohms.

Here is a thermocouple junction inside the
probe that is close to burning out. The
thermocouple should be replaced before this
happens as part of your preventative
maintenance program.

Here is an example where connections are made to a
4 wire sensor and the 525Plus indicates that only
Wires 1, 2 & 4 are connected. There may be a loose
connection or a break in wire 3 somewhere between
the sensor and the 525Plus.

This probe indicated OPEN on the
controller and shut down the process.
The resistance is <10,000 ohms
versus >100 ohms when new.

Only a calibrator with PIE’s secondary display of thermocouple probe
resistance makes troubleshooting thermocouples simple without requiring
additional testing equipment. This saves time and money over replacing fully
operational thermocouple too early or waiting for the thermocouples to fail.

Thermocouple, Millivolt, RTD & Milliamp Connections

Simulating or reading thermocouples requires the use of
thermocouple or extension grade thermocouple wire.

Plug thermocouple wires into the miniature thermocouple jack.
The PIE 525Plus has two banana jacks (1+ and 2-) mounted in
the top end of the housing. These are not temperature
compensated and are to be used only for millivolt signals. The
two banana jacks (5+ and 6-) are for all milliamp signals.

Simulating or reading RTDs uses copper wire.

Plug 2, 3 or 4 wires into the corresponding jacks on the
calibrator. For RTD source the PIE 525Plus simulates the (+)
RTD from jacks 1 & 4 and the (-) RTD from jacks 2 & 3.
When reading an RTD sensor the PIE 525Plus uses patented
circuitry to automatically detects if 2, 3 or 4 wires are connected.
This is helpful to troubleshoot sensor connections.
