General Information

Calibrate all your T/C & RTD Instruments

• Easy to use

With the PIE 525B you can check and calibrate

all your thermocouple and RTD instruments and

measure temperature sensors.

• Take it into the shop, plant or field

Carry it without worry - it comes protected with a

rubber boot and rugged, low profile switches.

Easy to operate even in the dark areas of the

plant with the backlit display.

•

Calibrate T/C instruments to 0.1 & 0.01 °F & °C

The PIE 525B works with the thermocouples

you use including types J, K, T, E, R, S, B, N, G,

C, D, L (J-DIN), U (T-DIN) and P (Platinel II). Or

calibrate from -13.0000 to +80.0000 mV.

• Calibrate RTD instruments to 0.1 & 0.01 °F & °C

Stop carrying around a decade box and RTD

resistance tables. The 525B works with the

RTDs you use including Platinum 10, 50, 100,

200, 500 & 1000 Ohm (alpha = 3850), Platinum

100 Ohm (alpha = 3902, 3916, 3926), Copper

10 & 50 Ohm, and Nickel 120 Ohm. Or calibrate

from 0.000 to 400.000 and 0.00 to 4000.00

Ohms.

• Fast calibration with automatic output

stepping

Easily set any value quickly to within 0.1° or 0.01°

with the adjustable digital potentiometer “DIAL”

plus store any three temperatures for instant

recall with the EZ-CHECK™ switch. Choose

between 2, 3, 5, 11 steps and ramp to

automatically increment the output in 100%, 50%,

25%, 10% or 5% of span. Select step time from

5, 6, 7, 8, 9, 10, 15, 20, 25, 30 & 60 seconds.

• Compatible with ALL process instruments

No competitor’s calibrator is compatible with as

many process instruments! Connect directly to the

temperature inputs of transmitters, PLCs, DCS &

multichannel recorders to verify their outputs or

displays. RTD simulation works with older

instruments with fixed excitation currents and newer

multichannel instruments that switch the excitation

current between input channels.

• Perform Heat Treating Uniformity Surveys and

System Accuracy Tests

The PIE 525B meets or exceeds the

requirement of AMS 2750 as a Secondary

Standard & as a Field Test Instrument.

• Measure thermocouple & RTD sensors

The PIE 525B measures probes to 0.1 or 0.01

°C or °F. Secondary display shows the millivolt

or resistance value corresponding to the sensor

Page 3

temperature. For T/Cs the cold junction

temperature measured by the calibrator. For

RTDs the fixed or pulsed sensor current

outputted by the measuring instrument is

measured by the calibrator.

• Find problems with troubleshooting tools

Open thermocouples and thermocouples that

have high resistance indicating impending failure

are indicated by OPEN TC on the display.

Troubleshoot RTD sensor connections and find

broken wires with patented technology. Connect

your two, three or four wire RTDs and the PIE

525B automatically detects the connections.

• Calibration Lab Accurate & Stable

The internal cold junction thermistor is accurate

to ±0.05°C and is traceable to NIST. The sensor

is thermally bonded to an isothermal mass

which includes brass blocks with screw

terminals for connection of bare thermocouple

wires along with a miniature thermocouple

connector for fast connections. The circuitry

uses an extremely stable voltage reference and

low drift components which make the PIE 525B

more accurate than most other handheld and

bench top thermocouple calibrators.

Patented Diagnostic Technology - Available only

with PIE Calibrators!

Simulating or reading thermocouples requires the use of

thermocouple or extension grade thermocouple wire.

Plug thermocouple wires into the miniature jack or place bare

thermocouple wires onto the brass block under the screws.

The PIE 525B has two banana jacks (1+ & 2-) mounted in the

top end of the housing. These are not temperature compensated

and are to be used only for millivolt signals or thermocouple

signals with the cold junction turned off.

Connections

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 525B simulates the (+) RTD

from jacks 1 & 4 and the (-) RTD from jacks 2 & 3.

When reading an RTD sensor the PIE 525B uses patented

circuitry to automatically detect if 2, 3 or 4 wires are connected.

This is helpful to troubleshoot sensor connection (see

Troubleshooting an RTD Sensor).

Operating Instructions

FIELD & BENCH USE

PIE 525B comes with a carrying case designed for hands-free

operation and a rubber boot with a built-in tilt stand. The PIE

525B is held in the case by elastic straps for use with the

carrying case open. The tilt stand is easily raised by pulling the

stand until it locks into place.

Operating Instructions

STORING HI and LO EZ-CHECK Source Outputs

Speed up your calibration by storing Span & Zero output setting

for instant recall with the EZ-CHECK switch.

1) Store your high (SPAN) output temperature by moving the

EZ-CHECK switch to the HI position and turning the EZ-Dial

knob until the desired output value is on the display. Press

and hold the EZ-Dial knob until STORED appears to store

the value. Release the EZ-Dial knob.

2) Store your low (ZERO) output value by moving the EZ-CHECK

switch to the LO position and turning the EZ-Dial knob until

the desired output value is on the display. Press and hold the

EZ-Dial knob until STORED appears to store the value.

Release the EZ-Dial knob.

3) Instantly output your SPAN and ZERO output settings by

moving the EZ-CHECK switch between HI and LO. You may

also select any third output setting (such as mid-range) using

the SET position on the EZ-CHECK switch.

CHANGING BATTERIES

Low battery is indicated by a battery symbol on the display.

Approximately one to four hours of typical operation remain before

the PIE 525B will automatically turn off. To change the batteries

remove the rubber boot and remove the battery door from the

back of the unit by sliding the door downward. This allows access

to the battery compartment. Replace with four (4) “AA” 1.5V

batteries being careful to check the polarity. Replace the battery

door and replace the boot. All stored configuration options (T/C

Type, EZ-CHECK Memories, etc.) are reset to factory settings

when the batteries are removed.

Note: Alkaline batteries are supplied and recommended for

typical battery life and performance. Optional rechargeable

batteries (charged externally) are available.

qEZ-CHECK™ SWITCH

SOURCE: Instantly output two preset settings by moving the

EZ-CHECK™ switch to the “LO” position or “HI” position.

For fast

three point checks select the “SET” position. The PIE 525B will

remember the last “SET” value, even with the power off.

These values can easily be changed to suit the calibration requirements.

The values stored in the HI and LO positions are also used for Auto

Stepping.

READ: Slide the switch to the SET position. The PIE 525B will display

the current reading from the sensor or device being measured. Slide

the switch to MAX and the highest value measured since turn-on or

reset will be displayed; slide the switch to MIN and the lowest value

measured since turn-on or reset will be displayed.
