Operating Precautions
• Avoid stepping on or pinching cables, which could damage the cable
insulation.
• To avoid breaking the cables and test leads, do not bend or pull
them.
• To avoid damaging the power cord, grasp the plug, not the cord,
when unplugging it from the power outlet.
• The sensor used in the temperature probe is a thin, precision
platinum film. Be aware that excessive voltage pulses or static
discharges can destroy the film.
• Avoid subjecting the temperature probe tip to physical shock, and
avoid sharp bends in the leads. These may damage the probe or
break a wire.
• When measuring high temperatures, do not let the handle of the
temperature probe or the compensation lead wire exceed the
temperature range.
Handling the Cords and Probes
Use only the specified test leads and cables. Using a non-specified
cable may result in incorrect measurements due to poor connection
or other reasons.
Instrument Installation and Operating Environment
• Do not install the instrument upside-down, or stand it on its side.
• Do not store or use the instrument where it could be exposed to
direct sunlight, high temperature or humidity, or condensation. Under
such conditions, the instrument may be damaged and insulation may
deteriorate so that it no longer meets specifications.
• This instrument is designed for use indoors. It can be operated at
temperatures between 0 and 40°C without degrading safety.
• This instrument is not designed to be entirely water- or dust-proof.
Do not use it in an especially dusty environment, nor where it might
be splashed with liquid. This may cause damage.
• Do not use the instrument near a source of strong electromagnetic
radiation, or near a highly electrically charged object. These may
cause a malfunction.
• Correct measurement may be impossible in the presence of strong
magnetic fields, such as near transformers and high-current
conductors, or in the presence of strong electromagnetic fields
such as near radio transmitters.
• In an electrically noisy environment, noise may impinge upon the
measured object, resulting in unstable measurements. The
instrument should not be used in such places.
