DANGER

NEVER touch parts where the label shown on the left is attached. Such

parts have high voltages of at least 1 kV and there is a risk of receiving a

fatal electric shock.

WARNING

1. ALWAYS refer to the operation manual when working near locations

at which the alert mark shown on the left is attached. If the advice in

the operation manual is not followed there is a risk of personal injury

or reduced equipment performance. The alert mark shown on the

left may also be used with other marks and descriptions to indicate

other dangers.

2. IEC 61010 Standard

The IEC 61010 standard specifies four categories to ensure that an

instrument is used only at locations where it is safe to make

measurements. This instrument is designed for measurement

category I (CAT I). DO NOT use this instrument at locations

specified as category II, III, or IV as defined below.

Measurement category I (CAT I):

Secondary circuits of a device that is not directly connected to a

power outlet.

Measurement category II (CAT II):

Primary circuits of a device that is directly connected to a power outlet,

e.g., portable tools or home appliance.

Measurement category III (CAT III):

Primary circuits of a device (fixed equipment) to which power is

supplied directly from the distribution panel, and circuits running from

the distribution panel to power outlet.

Measurement category IV (CAT IV):

Building service-line entrance circuits, and circuits running from the

service-line entrance to the meter or primary circuit breaker

(distribution panel).

For Safety

WARNING

3. To ensure that the instrument is earthed, always use the supplied 3-

pin power cord, and insert the plug into an outlet with an earth

terminal. If power is supplied without earthing the equipment, there

is a risk of receiving a severe or fatal electric shock or causing

damage to the internal components.

4. This equipment cannot be repaired by the operator. DO NOT attempt

to remove the equipment covers or unit covers or to disassemble

internal components. Only qualified service personnel with a

knowledge of electrical fire and shock hazards should service this

equipment. There are high-voltage parts in this equipment presenting

a risk of severe injury or fatal electric shock to untrained personnel. In

addition, there is a risk of damage to precision components.

5. The performance-guarantee seal verifies the integrity of the equipment.

To ensure the continued integrity of the equipment, only Anritsu service

personnel, or service personnel of an Anritsu sales representative,

should break this seal to repair or calibrate the equipment. If the

performance-guarantee seal is broken by you or a third party, the

performance of the equipment cannot be guaranteed. Be careful not

to break the seal by opening the equipment or unit covers.

6. This equipment should always be positioned in the correct manner.

If the cabinet is turned on its side, etc., it will be unstable and may be

damaged if it falls over as a result of receiving a slight mechanical

shock.

Always set up the equipment in a position where the power switch

can be reached without difficulty.

7. This instrument uses a Liquid Crystal Display (LCD). DO NOT subject

the instrument to excessive force or drop it. If the LCD is subjected to

strong mechanical shock, it may break and liquid may leak.

This liquid is very caustic and poisonous.

DO NOT touch it, ingest it, or get in your eyes. If it is ingested

accidentally, spit it out immediately, rinse your mouth with water and

seek medical help. If it enters your eyes accidentally, do not rub

your eyes, rinse them with clean running water and seek medical help.

If the liquid gets on your skin or clothes, wash it off carefully and

thoroughly.

For Safety

CAUTION

1. Always remove the mains power cable from the power outlet before

replacing blown fuses. There is a risk of electric shock if fuses are

replaced with the power cable connected. Always use new fuses of

the type and rating specified on the rear panel of the instrument.

There is a risk of fire if a fuse of a different rating is used.

T6.3A indicates a time-lag fuse.

There is risk of receiving a fatal electric shock if the fuses are

replaced with the power cord connected.

2. Keep the power supply and cooling fan free of dust.

•Clean the power inlet regularly. If dust accumulates around the

power pins, there is a risk of fire.

•Keep the cooling fan clean so that the ventilation holes are not

obstructed. If the ventilation is obstructed, the cabinet may

overheat and catch fire.

3. Use two or more people to lift and move this equipment, or use a

trolley. There is a risk of back injury, if this equipment is lifted by one

person.

4. Never input a signal of more than the indicated value between the

measured terminal and ground. Input of an excessive signal may

damage the equipment.
