1. GENERAL INSTRUCTIONS
This instru ent co plies with IEC 61010-1: 2001, CAT Ⅲ
1000V and CAT Ⅵ 600V overvoltage standards. See
Specifications.
To get the best service fro this instru ent, read this user's
anual carefully and respect the detailed safety
precautions.
International sy bols used on the Meter and in this anual
are explained in chapter 1.2.
1.1 Precautionary Safety Measures
I portant Note: Li ited Liability
Cascadia Innovations is the exclusive distributor of all
ennoLogic™ products. Except as explicitly stated,
Cascadia Innovations is not liable for direct, indirect,
incidental, or other types of da ages arising out of, or
resulting fro the use of this product. By using the
eM860T you agree to hold ennoLogic™ and Cascadia
Innovations har less for any and all consequences of the
use of this product or application of data fro the use of
this instru ent.

1.1.1 Preli inary
As the possibilities of high transient over-voltages occurring
in today’s power syste s increase, ore stringent safety
standards are set for electrical test equip ent. Transients on
electrical syste s (power grid, feeder or branch circuits) will
trigger a series of incidents that ay result in serious
personal injury. To protect you against transients, safety
ust be built into the test equip ent.
Overvoltage
category In brief Exa ples
CAT I Electronic
• Protected electronic
equip ent.
• Equip ent connected to
(source) circuits in
which easures are
taken to li it transient
over-voltages to an
appropriately low level.
• Any high-voltage, low-
energy source derived
fro a high winding
resistance transfor er,
such as the high-voltage
section of a copier.
3
CAT II
Single-phase
receptacle
connected
loads
• Appliance, portable
tools, and other household
and si ilar loads.
• Outlet and long branch
circuits.
• Outlets at ore than 10
eters (30 feet) fro CAT
III source.
• Outlets at ore that 20
eters (60 feet) fro CAT
IV source.
CAT III
Three-phase
distribution,
including
single-phase
co ercial
lighting
• Equip ent in fixed
installations, such as
switchgear and polyphase
otors.
• Bus and feeder in
industrial plants.
• Feeders and short
branch circuits,
distribution panel devices.
• Lighting syste s in
larger buildings.
• Appliance outlets with
short connections to
service entrance.
4
CAT VI
Three-phase at
utility
connection,
any outdoor
conductors
• Refers to the “origin of
installation”; i.e., where
low-voltage connection
is ade to utility power.
• Electricity eters,
pri ary overcurrent
protection equip ent.
• Outside and service
entrance, service drop
fro pole to building,
run between eter and
panel.
• Overhead line to
detached building,
underground line to well
pu p.
When using this Multi eter, the user ust observe all
nor al safety rules concerning:
•protection against the dangers of electric current.
•protection of the Multi eter against isuse.
For your own safety, only use the test probes supplied with
the instru ent. Before use, check that they are in good
condition.
