Infrared Thermometers

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 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.
