Instrument Safety Notices
WARNING
MAINTENANCE INSTRUCTIONS WITHIN THIS MANUAL ARE FOR USE BY QUALIFIED SERVICE PERSONNEL
ONLY. DO NOT ATTEMPT TO SERVICE THIS UNIT UNLESS YOU ARE QUALIFIED TO DO SO.
SHOCK HAZARD
Disconnect all temperature probes and turn the unit off before removing the battery cover.
Never connect thermocouple leads to any source where more than 42 Volts (peak) could exist
between the lead and ground. If it is necessary to make measurements of an object at elevated
electrical potential, the user is responsible for obtaining and properly using a probe that provides
adequate insulation between the surface with elevated potential and the thermocouple wiring.
Always disconnect probe leads before opening the battery door or the instrument housing.
Internal circuits can present a shock hazard if leads are connected to a source of elevated potential.
Do not use this instrument if the housing, probe wiring, probe, or probe handle are damaged
or distorted. Housings and wire insulation are part of the personnel protection system, and if damaged
could expose users to elevated potentials.
EXPLOSION HAZARD
Never use or store this product with batteries installed, or change batteries, in an
environment where explosive or flammable vapors or dust suspensions may exist.
Do not attempt to recharge alkaline batteries.
Do not put batteries into bags designed to protect parts from electrostatic discharge (ESD).
These bags are specially designed with metal shielding which can short circuit a battery.
Do not expose batteries to extreme heat or fire. Observe all regional laws and regulations when
disposing batteries.
Never use this instrument or any temperature probe or sensor inside a microwave oven.
