Safety Precautions

The following are general safety precautions that are not necessarily

related to any specific part or procedure, and do not necessarily appear

elsewhere in this publication. These precautions must be thoroughly

understood and apply to all phases of operation and maintenance.

Keep Away From Live Circuits

Operating personnel must at all times observe normal safety regulations.

Do not replace components or make adjustments inside the equipment

with high voltage turned on. To avoid casualties, always remove power.

Shock Hazard

Do not attempt to remove the RF transmission line while RF power is

present. Radiated RF power is a potential health hazard. Observe general

safety precautions for handling high voltage equipment. Always

disconnect power before attempting any repairs.

Do Not Service or Adjust Alone

Under no circumstances should any person reach into an enclosure for the

purpose of service or adjustment of equipment except in the presence of

someone who is capable of rendering aid.

Chemical Hazard

Dry cleaning solvents for cleaning parts may be potentially dangerous.

Avoid inhalation of fumes or prolonged contact with skin.

Safety Earth Ground

An uninterruptible earth safety ground must be supplied from the main

power source to test instruments. Grounding one conductor of a two

conductor power cable is not sufficient protection. Serious injury or death

can occur if this grounding is not properly supplied.

Resuscitation

Personnel working with or near high voltages should be familiar with

modern methods of resuscitation.

Safety Symbols

WARNING

Warning notes call attention to a procedure which, if not correctly

performed, could result in personal injury.

NOTE: Calls attention to supplemental information

Fuse Replacement

Always use the same type and rating of fuse when replacing the fuse.

Fuse information can be found in the parts list on page 30.

Warning Statements

The following safety warnings appear in the text where there is danger to

operating and maintenance personnel, and are repeated here for emphasis.

CAUTION

Caution notes call attention to a procedure which, if not correctly

performed, could result in damage to the instrument.

The caution symbol appears on the equipment

indicating there is important information in the

instruction manual regarding that particular area.

WARNING

Use only NIckel Metal Hydride (NiMH) batteries that have a minimum

capacity of 4600 milliamper hours (mAh). Do not install batteries that are

not Nickel Metal Hydride. Do not install NiMH batteries that have less

than 4600 mAh capacity. Failure to comply may result in damage to the

batteries, damage to the instrument, and injury to personnel from battery

chemicals.

WARNING

Use dry cleaning solvents in a well ventilated area. Avoid excessive

inhalation of solvent fumes, since they can be toxic in heavy concentrations.

Always wear eye protection and avoid skin contact with the solvent.

WARNING

Be sure that the power cable is unplugged before opening the wattmeter

case. The power supply capacitor, C1, can retain a dangerous charge that

must be removed before touching. Always have another person standing by

who is trained in electric shock first aid.

Caution Statements

The following equipment cautions appear in the text whenever the

equipment is in danger of damage, and are repeated here for emphasis.

CAUTION

Long-term storage of this instrument can affect battery performance and

reduce battery life. Do not store the instrument for long periods of time

without recharging the batteries (refer to page 19). Failure to comply may

result in reduced battery charge and shortened battery life.

CAUTION

If the element cannot be fully inserted into the socket, do not force

it. You might damage the element.

CAUTION

Internal batteries are connected. Remove one of the battery tubes before

unsoldering wires connected to the Main PCB. Failure to comply may result

in permanent equipment damage and severe shock to individuals.

CAUTION

Never apply RF power to the Model 4391A Wattmeter unless both line

section sockets are filled with either an element or a dust plug. If an

element is used it is advisable to place the element with the arrow at a 90°

angle to the coaxial line.

CAUTION

Always be certain the 115/230 voltage selector is set to the proper voltage

before ac power is applied.

CAUTION

Always disconnect AC power before opening the Model 4391 enclosure.

Removal of at least one battery cell is also recommended when servicing the

instrument.

CAUTION

This instrument contains static sensitive electronic components. Before

opening or servicing the unit, make sure that you understand and practice

electrostatic discharge component handling. Failure to comply may result

in permanent damage to sensitive components.
