WARNING and PRECAUTIONS
• To avoid electrical shock, do not use this instrument
when working voltages at the measurement surface
over 24V AC or DC.
• To avoid damage or burns, do not make
temperature measurement in microwave ovens.
• Repeated sharp exing can break the thermocouple
leads. To prolong lead life, avoid sharp bends in the
leads, especially near the connector.

pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection. This
equipment generates, uses and can radiated radio
frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful
interference to radio communications. However, there

3
is no guarantee that interference will not occur in a
particular installation if this equipment does cause
harmful interference to radio or television reception,
which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and
receiver.
• Connect the equipment into an outlet on a
circuit different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV
technician for help.
Shielded interface cables must be used in order to comply
with emission limits.
Changes or modifications not expressly approved by the
party responsible for compliance could void the user’s
authority to operate the equipment.
