External Contact Probe

XWWarning

To avoid electrical shock or personal injury, do not connect the external contact probe to live electrical circuits.

The thermometers come with a bead K-type thermocouple probe. The probes attach to the thermometers via the probe input located on the top of the thermometer (see Figure 7).

With the probe installed, the probe symbol (A) appears on the display. The probe can be used simultaneously while the thermometer is taking non-contact measurements. The probe readings are shown below the non-contact measurements. The thermometer will stay on when there is a probe inserted. When used with a personal computer and FlukeView Forms (568 only), the auto off feature is disabled.

Use the following table to remedy possible problems when using the thermometer.
