Fluke 80PK-1 Operation, Measuring Technique, Temperature Limitations, Media Limitations

junction compensation. Accuracy of the temperature measuring instrument must be considered along with the 80PK-1 accuracy specification in order to determine the overall accuracy of the combination.

Temperature Limitations

The 260°C continuos temperature rating of the 80PK-1 is primarily determined by the Teflon insulation. The bead alone may be momentarily subjected to higher temperatures without damage.

Media Limitations

Type K Chromel-Alumel thermocouple wires are compatible with clean oxidizing atmospheres.

OPERATION

Caution

Repeated sharp bending can break the 80PK-1 lead. To protect the lead, avoid sharp bends, especially near the connector.

Use the 80PK-1 as follows:

1.Connect the 80PK-1 to a compatible Type K temperature measuring instrument using the miniature (0.312-inch pin spacing) thermocouple connector.

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

3.Check the readout on the measuring instrument. With no heat or cold source applied to the bead, it should display the ambient (room) temperature. If the instrument does not readout properly, refer to the TROUBLESHOOTING section below.

MEASURING TECHNIQUE

Here are some suggestions for improving the accuracy of your temperature measurements:

1.Make sure that there is a good connection between the probe and the surface you are measuring by doing any of the following:

a. Increase the mounting pressure.
