Earth Ground

LEAKAGE TEST

The AC leakage from any exposed metal part to earth ground

and from all exposed metal parts to any exposed metal part having

a return to chassis, must not exceed 0.5 mA (500 microamperes).

Leakage current can be measured by any one of three methods.

1. A commercial leakage tester, such as the Simpson 229 or RCA

WT-540A. Follow the manufacturers' instructions to use these

instruments.

2. A battery-operated AC milliammeter. The Data Precision 245

digital multimeter is suitable for this job.

3. Measuring the voltage drop across a resistor by means of a VOM

or battery-operated AC voltmeter. The "limit" indication is

0.75V, so analog meters must have an accurate low-voltage scale.

The Simpson 250 and Sanwa SH-63Trd are examples of a

passive VOM that is suitable. Nearly all battery operated digital

multimeters that have a 2V AC range are suitable. (See Fig. A)

1. Check the area of your repair for unsoldered or poorly-soldered

connections. Check the entire board surface for solder splashes

and bridges.

2. Check the interboard wiring to ensure that no wires are

"pinched" or contact high-wattage resistors.

3. Look for unauthorized replacement parts, particularly transistors,

that were installed during a previous repair. Point them out to

the customer and recommend their replacement.

4. Look for parts which, though functioning, show obvious signs

of deterioration. Point them out to the customer and recommend

their replacement.

5. Check the line cord for cracks and abrasion. Recommend the

replacement of any such line cord to the customer.

6. Check the B+ voltage to see it is at the values specified.

7. Check the antenna terminals, metal trim, "metallized" knobs,

screws, and all other exposed metal parts for AC leakage. Check

leakage as described below.

SAFETY CHECK-OUT

After correcting the original service problem, perform the following

safety checks before releasing the set to the customer:

Unleaded solder

Boards requiring use of unleaded solder are printed with the lead-

free mark (LF) indicating the solder contains no lead.

(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size.)

: LEAD FREE MARK

Unleaded solder has the following characteristics.

· Unleaded solder melts at a temperature about 40°C higher than

ordinary solder.

Ordinary soldering irons can be used but the iron tip has to be

applied to the solder joint for a slightly longer time.

Soldering irons using a temperature regulator should be set to

about 350

°C.

Caution: The printed pattern (copper foil) may peel away if the

heated tip is applied for too long, so be careful!

· Strong viscosity

Unleaded solder is more viscous (sticky, less prone to flow) than

ordinary solder so use caution not to let solder bridges occur such

as on IC pins, etc.

· Usable with ordinary solder

It is best to use only unleaded solder but unleaded solder may

also be added to ordinary solder.

PRECAUTIONS

1 SAFETY PRECAUTIONS

1) Before returning an instrument to the customer, always make a

safety check of the entire instrument, including, but not limited

to, the following items:

(1) Be sure that no built-in protective devices are defective or have

been defeated during servicing.

(1)Protective shields are provided to protect both the technician

and the customer. Correctly replace all missing protective

shields, including any removed for servicing convenience.

(2)When reinstalling the chassis and/or other assembly in the

cabinet, be sure to put back in place all protective devices,

including, but not limited to, nonmetallic control knobs,

insulating fish papers, adjustment and compartment covers/

shields, and isolation resistor/capacitor networks. Do not operate

this instrument or permit it to be operated without all protective

devices correctly installed and functioning.

(2) Be sure that there are no cabinet openings through which adults

or children might be able to insert their fingers and contact a

hazardous voltage. Such openings include, but are not limited

to, excessively wide cabinet ventilation slots, and an improperly

fitted and/or incorrectly secured cabinet back cover.

(3) Leakage Current Hot Check-With the instrument completely

reassembled, plug the AC line cord directly into a 120V AC

outlet. (Do not use an isolation transformer during this test.)

Use a leakage current tester or a metering system that complies

with American National Standards institute (ANSI) C101.1

Leakage Current for Appliances and Underwriters Laboratories

(UL) 1270 (40.7). With the instrument's AC switch first in the

ON position and then in the OFF position, measure from a known

earth ground (metal water pipe, conduit, etc.) to all exposed

metal parts of the instrument (antennas, handle brackets, metal

cabinets, screwheads, metallic overlays, control shafts, etc.),

especially any exposed metal parts that offer an electrical return

path to the chassis.

Any current measured must not exceed 0.5mA. Reverse the

instrument power cord plug in the outlet and repeat the test. See

Fig. 1.

Any measurements not within the limits specified herein indicate

a potential shock hazard that must be eliminated before returning

the instrument to the customer.

(4) Insulation Resistance Test Cold Check-(1) Unplug the power

supply cord and connect a jumper wire between the two prongs

of the plug. (2) Turn on the power switch of the instrument. (3)

Measure the resistance with an ohmmeter between the jumpered

AC plug and all exposed metallic cabinet parts on the instrument,

such as screwheads, antenna, control shafts, handle brackets,

etc. When an exposed metallic part has a return path to the

chassis, the reading should be between 1 and 5.2 megohm. When

there is no return path to the chassis, the reading must be infinite.

If the reading is not within the limits specified, there is the

possibility of a shock hazard, and the instrument must be repared

and rechecked before it is returned to the customer. See Fig. 2.

2) Read and comply with all caution and safety related notes on or

inside the cabinet, or on the chassis.

3) Design Alteration Warning-Do not alter or add to the mechanical

or electrical design of this instrument. Design alterations and

additions, including but not limited to, circuit modifications and

the addition of items such as auxiliary audio output connections,

might alter the safety characteristics of this instrument and create

a hazard to the user. Any design alterations or additions will

make you, the servicer, responsible for personal injury or

property damage resulting therefrom.

4) Observe original lead dress. Take extra care to assure correct

lead dress in the following areas:

(1) near sharp edges, (2) near thermally hot parts (be sure that

leads and components do not touch thermally hot parts), (3) the

AC supply, (4) high voltage, and (5) antenna wiring. Always

inspect in all areas for pinched, out-of-place, or frayed wiring,

Do not change spacing between a component and the printed-

circuit board. Check the AC power cord for damage.

5) Components, parts, and/or wiring that appear to have overheated

or that are otherwise damaged should be replaced with

components, parts and/ or wiring that meet original

specifications.

Additionally, determine the cause of overheating and/or damage

and, if necessary, take corrective action to remove any potential

safety hazard.
