SERVICING PRECAUTIONS
CAUTION
Before servicing instruments covered by this service manual, its supplements and addendum, read
and follow the SAFETY PRECAUTIONS of this manual.
NOTE
If unforeseen circumstances create conflict between the following servicing precautions and any of
the safety precautions on page 1 of this manual, always follow the safety precautions.
Remember: Safety First.
u General Servicing Precautions
1. Always unplug the AC power cord from the AC power source before:
a. Removing or reinstalling any component, circuit board, module, or any other instrument assembly.
b. Disconnecting or reconnecting any electrical plug or other electrical connection.
c. Connecting a test substitute in parallel with an electrolytic capacitor in the instrument.
CAUTION
A wrong part substitution or incorrect polarity installation of electrolytic capacitors may result in a
explosion hazard.
2. Do not any spray chemicals on or near this instrument or any or its assemblies.
3. Unless specified otherwise in this service manual, clean electrical contacts by applying the following
mixture to the contacts with a pipe cleaner, cotton-tipped stick or comparable nonabrasive applicator:
10% (by volume) Aceton and 90% (by volume) isopropyl alchohol (90%-99% strength).
CAUTION
This is a flammable mixture. Unless specified otherwise in this service manual, lubrication of contacts
is not required.
4. Do not apply AC power to this instrument and/or any of its electrical assemblies unless all solid-state
device heat sinks are correctly installed.
5. Always connect the test instrument ground lead to the appropriate instrument chassis ground before
connecting the test instrument positive lead. Always remove the test instrument ground lead last.
6. Use only the test fixtures specified in this service manual with this instrument.
CAUTION
Do not connect the test fixture ground strap to any heatsink in this instrument.

SERVICING PRECAUTIONS
u Electrostatically Sensitive (ES) Devices
Some semiconductor (solid state) devices can be damaged easily by static electricity.
Such components commonly are called Electrostatically Sensitive (ES) Devices.
The examples of typical ES devices are integrated circuits, some field-effect transistors and
semiconductor "chip" components. The following techniques should be used to help reduce the
incidence of component damage caused by static electricity.
1. Immediately before handling any semiconductor component or semiconductor-equipped assembly,
drain off any electrostatic charge on your body by touching a known earth ground. Alternatively,
obtain and wear a commercially available discharging wrist strap device which should be removed for
potential shock reasons prior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive
surface such as aluminum foil to prevent electrostatic charge buildup or exposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.
4. Use only an anti-static type solder removal device. Some solder removal devices not classified as
"anti-static" can generate enough electrical charges to damage ES devices.
5. Do not use freon-propelled chemicals. These can generate enough electrical charges to damage ES devices.
6. Do not remove a replacement ES device from its protective package until immediately before you are
ready to install it. (Most replacement ES devices are packaged with leads electrically shorted together
by conductive foam, aluminum foil or comparable conductive material).
7. Immediately before removing the protective material from the leads of a replacement ES device,
touch the protective material to the chassis or circuit assembly into which the device will be installed.
CAUTION
Be sure that no power is applied to the chassis or circuit, and observe all other safety precautions.
8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmful
motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted
floor can generate enough static electricity to damage an ES devices).
u General Soldering Guidelines
1. Use a grounded-tip, low-wattage soldering iron with appropriate tip size and shape that will maintain
tip temperature within a 550°F-660°F (288°C-316°C) range.
2. Use an appropriate gauge of RMA resin-core solder composed of 60 parts tin/40 parts lead.
3. Keep the soldering iron tip clean.
4. Throughly clean the surface to be soldered. Use a small wire-bristle (0.5 inch or 1.25cm) brush with a
metal handle. Do not use freon-propelled spray-on cleaners.
5. Use the following soldering technique:
a. Allow the soldering iron tip to reach normal temperature (550°F to 660°F or 288°C to 316°C)
b. Hold the soldering iron tip and solder strand against the component lead until the solder melts.
c. quickly move the soldering iron tip to the junction of the component lead and the printed circuit foil,
and hold it there only until the solder flows onto and around both the component lead and the foil.
d. Closely inspect the solder area and remove any excess or splashed solder with a small wire-bristle brush.
CAUTION
Work quickly to avoid overheating the circuit board printed foil.

SERVICING PRECAUTIONS
FIGURE1. USE SOLDERING IRON TO PRY LEADS
u IC Removal / Replacement
Some utilized chassis circuit boards have slotted (oblong) holes through which the IC leads are inserted
and then bent flat against the circuit foil. When holes are slotted, the following technique should be used
to remove and replace the IC. When working with boards using the familiar round hole, use the standard
technique as outlined in paragraphs 5 on the page under the title of general soldering guidelines.
u Removal
1. Desolder and straighten each IC lead in one operation by gently prying up on the lead with the solder-
ing iron tip as the solder melts.
2. Draw away the melted solder with an anti-static suction-type solder removal device (or with desolder-
ing braid before removing the IC.
u Replacement
1. Carefully insert the replacement IC in the circuit board.
2. Carefully bend each IC lead against the circuit foil pad and solder it.
3. Clean the soldered areas with a small wire-bristle brush. (lt is not necessary to reapply acrylic coating
to the area).
u "Small-Signal" Discrete Transistor Removal/Replacement
1. Remove the defective transistor by clipping its leads as close as possible to the component body.
2. Bend the end of each of three leads remaining on the circuit board into a "U" shape.
3. Bend the replacement transistor leads into a "U" shape.
4. Connect the replacement transistor leads to the corresponding leads extending from the circuit board
and crimp the "U" with long nose pliers to insoure metal-to-metal contact, then solder each
connection.
6
SERVICING PRECAUTIONS
u Power IC, Transistor or Devices Removal / Replacement
1. Heat and remove all solders from the device leads.
2. Remove the heatsink mounting screw (if applicable).
3. Carefully remove the device from the circuit board.
4. Insert new device in circuit board.
5. Solder each device lead, and clip off excess lead.
6. Replace heatsink.
u Diode Removal / Replacement
1. Remove defective diode by clipping its leads as close as possible to diode body.
2. Bend the two remaining leads perpendicularly to the circuit board.
3. Observing diode polarity, wrap each lead out of the new diode around the corresponding lead on the
circuit board.
4. Securely crimp each connection and solder it.
5. Inspect the solder joints of the two "original" leads on the circuit board copper side. If they are not
shiny, reheat them and apply additional solder if necessary.
