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.
