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
Do not place any heavy object on the GSP-818.
Avoid severe impact or rough handling that
leads to damaging the GSP-818.
Do not discharge static electricity to the GSP-
818.
Do not block or obstruct the cooling fan vent
openings.
Do not perform measurement at circuits directly
connected to Mains (Note below).
Do not disassemble the GSP-818 unless you are
qualified as service personnel.
The equipment is not for measurements
performed for CAT II, III and IV.
(Measurement categories) EN 61010-1:2010 specifies the
measurement categories and their requirements as follows. The
GSP-818 falls under category I.
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.
0 is for measurements performed on circuits not directly
connected to Mains.

Power Supply
WARNING
AC Input voltage range: 100-240Vac;
Frequency: 50/60Hz
Connect the protective grounding conductor of
the AC power cord to an earth ground, to avoid
electrical shock.
Cleaning the
GSP-818
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 or cleaners 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 40°C
Altitude: Up to 2000m
Transient Overvoltage on the main supply is
2500V.
(Pollution Degree) EN 61010-1:2010 specifies the pollution degrees
and their requirements as follows. THE GSP-818 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.

Power cord for the United Kingdom
When using the GSP-818 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
0.75mm2 should 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.
