External Contact Probe; Troubleshooting - Fluke 56x User Manual

External Contact Probe

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 9).
With the probe installed, the probe symbol () 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.
