SAFETY INSTRUCTIONS
This chapter contains important safety instructions that you must
follow during operation and storage. Read the following before
any operation to ensure your safety and to keep the instrument in
the best possible condition.
Safety Symbols
These safety symbols may appear in this manual or on the instrument.
WARNING
Warning: Identifies conditions or practices that could result in
injury or loss of life.
CAUTION
Caution: Identifies conditions or practices that could result in
damage to the DMM or to other properties.
DANGER High Voltage
Attention Refer to the Manual

Do not dispose electronic equipment as unsorted municipal
waste. Please use a separate collection facility or contact the
supplier from which this instrument was purchased.
Safety Guidelines
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 the terminals.
Do not block or obstruct the cooling fan vent opening.
Do not perform measurement at the source of a low-voltage
installation or at building installations (Note below).
Do not disassemble the instrument unless you are qualified as
service personnel.
Make sure that the COM terminal to earth is limited to 500Vpk.
Remove all test leads before disconnecting the mains power
cord from the socket.

SAFETY INSTRUCTIONS
17/11/2016 Version No. 002 5
(Note) EN 61010-1:2010 specifies the measurement categories and their
requirements as follows. The IDM-8351 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.
Power Supply
WARNING
AC Input voltage: 100/120/220/240 V AC
50/60Hz
The power supply voltage should not fluctuate more than 10%.
Connect the protective grounding conductor of the AC power
cord to an earth ground, to avoid electrical shock.
Fuse
WARNING
Fuse type: 0.125AT 100/120VAC
0.063AT 220/240 VAC
Make sure the correct type of fuse is installed before power up.
To avoid risk of fire, replace the fuse only with the specified
type and rating.
Disconnect the power cord before fuse replacement.
Make sure the cause of a fuse blowout is fixed before fuse
replacement.

Cleaning the
Instrument
Disconnect the power cord before cleaning.
Use a soft cloth dampened in a solution of mild detergent and
water. Do not spray any liquid.
Do not use chemicals containing harsh material such as
benzene, toluene, xylene, and acetone.
Operation
Environment
Location: Indoor, no direct sunlight, dust free, almost non-
conductive pollution (Note below)
Temperature: 0°C to 50°C
Humidity: < 30°C: < 80%RH(non-condensing);
30°C~40°C:<70%RH(non-condensing); >40°C:
<50%RH (non-condensing)
Altitude: <2000m
(Note) EN 61010-1:2010 specifies the pollution degrees and their requirements as
follows. The IDM-8351 falls under degree 2.
Pollution refers to “addition of foreign matter, solid, liquid, or gaseous (ionized
gases), that may produce a reduction of dielectric strength or surface
resistivity”.
Pollution degree 1: No pollution or only dry, non-conductive pollution occurs.
The pollution has no influence.
Pollution degree 2: Normally only non-conductive pollution occurs.
Occasionally, however, a temporary conductivity caused by condensation must
be expected.
Pollution degree 3: Conductive pollution occurs, or dry, non-conductive
pollution occurs which becomes conductive due to condensation which is

expected. In such conditions, equipment is normally protected against
exposure to direct sunlight, precipitation, and full wind pressure, but neither
temperature nor humidity is controlled.
Storage
environment
Location: Indoor
Temperature: -40°C to 70°C
Humidity: <90%RH(non-condensing)
Disposal
Do not dispose this instrument as unsorted municipal waste.
Please use a separate collection facility or contact the supplier
from which this instrument was purchased. Please make sure
discarded electrical waste is properly recycled to reduce
environmental impact.

Power cord for the United Kingdom
When using the unit in the United Kingdom, make sure the power cord meets the
following safety instructions.
NOTE: This lead/appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the following code:
Green/ Yellow:
Earth
Blue:
Neutral
Brown:
Live (Phase)
As the colours of the wires in main leads may not correspond with the coloured
marking identified in your plug/appliance, proceed as follows:
The wire which is coloured Green & Yellow must be connected to the Earth terminal
marked with either the letter E, the earth symbol or coloured Green/Green &
Yellow.
The wire which is coloured Blue must be connected to the terminal which is marked
with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the terminal marked with
the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment or contact the
supplier.
This cable/appliance should be protected by a suitably rated and approved HBC
mains fuse: refer to the rating information on the equipment and/or user instructions
for details. As a guide, a cable of 0.75mm2should be protected by a 3A or 5A fuse.
Larger conductors would normally require 13A types, depending on the connection
method used.
Any exposed wiring from a cable, plug or connection that is engaged in a live
socket is extremely hazardous. If a cable or plug is deemed hazardous, turn off the
mains power and remove the cable, any fuses and fuse assemblies. All hazardous
wiring must be immediately destroyed and replaced in accordance to the above
standard.
