Electrical Safety Precautions
An uninterruptible safety earth ground must be provided from the main power source to the GT-1000A.
Any interruption of the protective ground conductor (internal or external to the instrument) or
disconnecting the protective earth terminal will cause a potential shock hazard that could result in personal
injury.
Grounding a single conductor of a two conductor outlet is insufficient protection. Additionally, verify that a
common ground exists between the unit under test, any additional test equipment, and this instrument
prior to energizing any unit.
Whenever it is likely that the protection has been impaired, the instrument must be removed from service
and secured against unintended operation.
If this instrument is to be energized via an autotransformer (for voltage reduction), ensure that the common
terminal is connected to neutral.
Servicing instructions are for use by service–trained personnel only. To avoid personal injury, do not perform
any service unless qualified to do so.
Adjustments described in the manual are performed with the unit energized and protective covers removed.
Energy available, at many points, may cause personal injury.
For continued protection against fire hazard, replace the line fuse only with a 250V fuse of the same current
rating and type. Do not use repaired fuses or short circuited fuse holders.
1.6
Important Operating Precautions
The GT-1000A Amplifier does not include an enable/disable feature to activate and deactivate the amplifier.
When connecting or disconnecting the output of the amplifier, ensure that the power switch of the amplifier
is in the OFF position.
The amplifier is capable of power output levels greater than 15 Watts. Devices connected to the output of
the amplifier must be rated to handle 25 Watts or higher. Exceeding the rated output power of a device will
result in permanent damage.
When connecting the amplifier to a transmitting device, observe all safety procedures to ensure that the
amplifier isn’t interfering with other systems in the area. High power microwaves can adversely affect power
sensitive instruments in the area of transmission.
Exercise precautions to avoid exposure to radiated microwave energy at all times.
