General Guideline
CAUTION
• Make sure that the voltage input level does not
exceed DC1000V/AC750V.
• Make sure the current input level does not exceed
12A.
• Do not place any heavy object on the instrument.
• Avoid severe impact or rough handling that can
lead to damaging the instrument.
• Do not discharge static electricity to the
instrument.
• Use only mating connectors, not bare wires, for

• Do not disassemble the instrument unless you are
qualified as service personnel.
• Make sure that the COM terminal to earth is
limited to 500Vpk.
(Note) EN 61010-1:2010 specifies the measurement
categories and their requirements as follows. The
IDM-8341/ 8342 falls under category II 600V.
• Measurement category IV is for measurement
performed at the source of low-voltage installation.
• Measurement category III is for measurement
performed in the building installation.
• Measurement category II is for measurement
performed on the circuits directly connected to the
low voltage installation.
