SAFETY INSTRUCTIONS
This chapter contains important safety instructions that
you must follow when operating the GSP-830 and when
keeping it in storage. Read the following before operating
this instrument to ensure your safety and to keep the
GSP-830 in best condition.
Safety Symbols
These safety symbols may appear in this manual or on the GSP-830.
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 GSP-830 or to other properties.
DANGER High Voltage
Attention Refer to the Manual
Protective Conductor Terminal
Earth (ground) Terminal
Safety Guidelines
General Guideline
CAUTION
•Make sure that the RF input level and the Tracking
Generator output reversed power level do not exceed
+30dBm.
•Do not supply an input signal to the Tracking Generator
output.
•Do not place any heavy object on the GSP-830.
•Avoid severe impacts or rough handling that leads to
damaging the GSP-830.
•Do not discharge static electricity onto the GSP-830.

SAFETY INSTRUCTIONS
7
•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 a power generating source
or building installation site (Note below).
•Do not disassemble the GSP-830 unless you are technically
qualified.
(Note) EN 61010-1:2001 specifies the measurement categories and
their requirements as follows. The GSP-830 falls under category II.
•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 to 240 V AC, 50/60Hz, 90W
maximum
•DC Input voltage: 12V DC, 40W maximum
•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.
Battery
CAUTION
•Rating: 11.1V lithium-ion battery pack x 2
•Turn off the main power switch before installing or taking
out the battery packs.
Fuse
WARNING
•Fuse type: T1.6A/ 250V, time-delay, 5x20mm glass
•To ensure fire protection, replace the fuse only with the
specified type and rating.
•Disconnect the power cord before fuse replacement.
•Make sure the cause of fuse blowout is fixed before fuse
replacement.
Cleaning the
GSP-830
•Disconnect the power cord before cleaning.
•Use a soft cloth dampened in a solution of mild detergent
and water. Do not spray any liquid into the GSP-830.
•Do not use chemicals or cleaners containing harsh
products such as benzene, toluene, xylene, and acetone.
Operation
Environment
•Location: indoor, no direct sunlight, dust free, almost
non-conductive pollution (Note below)
•Relative Humidity: < 90%
•Altitude: < 2000m
•Temperature: 18°C to 28°C
Storage
Environment
•Location: indoor
•Relative humidity: < 85%
•Temperature: 0°C to 40°C

GSP-830 User Manual
8
(Note) EN 61010-1:2001 specifies the pollution degrees and their
requirements as follows. The GSP-830 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-830 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 mains leads may not correspond with the colour markings
identified in your plug/appliance, proceed as follows:
The wire which is coloured Green & Yellow must be connected to the Earth terminal
marked with the letter E or by the earth symbol or coloured Green or 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, 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 moulded mains connector that requires removal /replacement must be destroyed by
removal of any fuse & fuse carrier and disposed of immediately, as a plug with bared wires
is hazardous if a engaged in live socket. Any re-wiring must be carried out in accordance
with the information detailed on this label.
