Instruction Sheet

XWWarning

To avoid electrical shock, do not use this probe

when voltages exceeding 24 V ac rms or 60 V dc

are present. The probe tip is electronically

connected to the output terminals.

XW Attention

Pour éviter les risques d’électrocution, ne pas

utiliser cette sonde quand la tension est

sepérieure à 24 V efficaces en courant alternatif

ou 60 V en courant continu. La pointe de la sonde

est reliée électriquement aux bornes de sorties.

XW Warnung

Um Elektroschock zu vermeiden, dürfen Sie den

Meßstift nicht in der Anwesenheit von

Spannungen über 24V Wechselstrom oder 60V

Gleichstrom verwenden. Die Spitze des Meßstifts

ist mit den Ausgangsanschlüssen elektrisch

verbunden.

XW Advertencia

Para evitar descargas eléctricas, no use esta

sonda cuando se apliquen voltajes que

sobrepasen 24 V ca rcm o 60 V cc. La punta de la

sonda está conectada eléctricamente a las

terminales de salida.

Measurement Considerations

Instrument Compatibility

The 80PK-27 is designed to be compatible with any

temperature measuring instrument that accepts Type K

thermocouples, has a miniature thermocouple connector, and

has cold reference junction compensation. Accuracy of the

temperature measuring instrument must be considered along

with the 80PK-27 accuracy specifications in order to determine

the overall accuracy of the combination.

Temperature Limitations

The probe tip has continuous temperature rating of 600 °C.

However the rest of the assembly is rated for a lower

temperature. See the specifications for further information.

Media Limitations

Media must be compatible with Chromel, Alumel, and 303

stainless steel.

Application Information

At high temperatures, a surface temperature probe removes a

small amount of heat from the measured surface. At 600 °C on

a polished metal surface, the temperature at a contact point

will be lowered, typically not more than 2 °C. A lowering of the

temperature at the contact point is less likely (and contact

response time is quicker) on clean, polished, thermally

conductive surfaces than on materials with low thermal

conductivity, such as plastic or rough, contaminated surfaces.

To obtain the best thermal contact and performance, the

stainless steel ring must make full and firm contact with the

measurement surface.

Operation

Use the 80PK-27 as follows:

1. Using the miniature thermocouple connector, connect the

80PK-27 to a compatible Type K temperature measuring

instrument.

2. Turn on the measuring instrument and select the

appropriate range and scale.

3. Read the temperature on the measuring instrument. When

no heat or cold is applied to the sensing ribbon, the

measuring instrument should display the ambient (room)

temperature. If the instrument does not readout properly,

refer to “Troubleshooting”.

Measuring Technique

To improve the accuracy of your temperature measurements:

• When measuring higher than ambient temperatures,

adjust the connection between the probe and the surface

until you get the highest temperature reading.

• When measuring lower than ambient temperatures, adjust

the connection between the probe and the surface until

you get the lowest temperature reading.

• When measuring near ambient temperatures, make the

reading when the thermometer readout is most stable.

Troubleshooting

When no heat or cold applied to the probe, the measuring

instrument should display the ambient temperature. If the

measuring instrument does not do so, try the following:

1. Verify that the temperature measuring instrument is

designed for Type K thermocouples. It should have a

yellow input connector and/or be marked “K”.

2. Check for an open circuit indicator on the measuring

instrument. Some temperature measuring instruments

have a built-in circuit to indicate if the connected probe is

open. (All Fluke instruments have this feature.) Refer to

instrument's owner’s manual to see if this feature is

available.

If you suspect a broken connection, use an ohmmeter to

check probe continuity from pin to pin. If the ohmmeter

should read 10 ohms or less if there is continuity.

3. Short the two input pins of the measuring instrument with

a piece of wire. If the instrument is functioning it should

indicate the ambient temperature.
