1.4 Operating Precautions
1.4.1 Power Supply Voltage
Confirm the voltage of the power source before you connect the power cord to it.
The power requirements of this instrument are indicated on its rear panel.
Only use a power source that supplies a voltage within the operating voltage range and has a
frequency of 50/60 Hz.
1.4.2 Maximum Allowable Input Voltage
The maximum signal voltage that can be applied to the input connectors is indicated below.
Do not apply excessive voltage to the connectors. Doing so may damage the device or lead to
injury.

1.4.3 Mechanical Shock
This instrument contains sensitive components, so it may be damaged if it is dropped or
otherwise exposed to a strong shock.
1.4.4 Electrostatic Damage
Electronic components can be damaged by static discharge. Static electricity can build up in the
core wire of a coaxial cable. Before connecting a coaxial cable to an I/O connector of the
instrument, short the core wire of the cable with the external conductor.
1.4.5 Warming Up
To ensure more accurate measurements, turn ON the instrument approximately 30 minutes
before you intend to use it to allow its internal temperature to stabilize.
