• Do not block the vent holes on the side and bottom of the
instrument’s terminator. Doing so will cause the internal
temperature to rise and may lead to fire or malfunction.
• If you want to connect this instrument to a measuring
instrument on which isolation is not available between the
input terminal and case or between the input terminal and
other input terminals, note the following.
The instrument’s reference potential is the grounding potential.
Do not apply electric potential with different grounds to the
other input terminals. Doing so will cause short circuit current
to flow from the ground terminal through the 701934 power
supply unit or this instrument and may cause electric shock or
damage to the devices.
• Do not short-circuit between the two measurement lines with
the metal part of the sensor unit. It may lead to a serious
accident such as the occurrence of an arc.
• Use this instrument within the operating temperature and
humidity ranges.
• To prevent electric shock or fire or damage to this instrument,
do not install in the following places.
• In direct sunlight or hot location.
• In the presence of flammable gases or vapors. Using
this instrument in the following environment is extremely
dangerous.
• In a dusty environment or in an environment where the
instrument is exposed to water, oil, chemicals, or solvents.
This instrument is not waterproof or dustproof.
• In a strong magnetic field or near objects charged with static
electricity.
• Near a high frequency dielectric heating device, IH
cookware, or other dielectric heating equipment.
• In an environment subject to large levels of mechanical
vibration.
• Near high frequency power equipment.
