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. Turn on the measuring instrument and select the appropriate range and scale. 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". 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.

Cleaning
Dip ¼" of the probe tip in the water. Do not dip the entire probe tip! Brush lightly with a toothbrush. Excessive or abrasive brushing can damage the probe and void the warranty. If necessary you can dip the brush, but not the probe, into rubbing alcohol. To dry the probe, bake it for a minimum of two hours at 150-200 °F (66-93 °C). Baking at temperatures above 200 °F (93 °C) can damage the cord and void the warranty.
