Whadda Wsedu09 Educational Pc Oscilloscope Kit Instruction Manual (+ PDF)

This product is an educational PC oscilloscope kit. It offers
various features such as duty cycle measurement, frequency
measurement, transient recording, and spectrum analysis. It
requires a minimum system configuration to operate.

Minimum System Requirements:

WindowsTM operating system

Assembly Instructions:

Skipping the assembly process can lead to troubles. Follow these
instructions carefully to ensure a successful project.

1. Make sure you have the right tools:

A soldering iron with a small tip and soldering wire are
necessary for assembly. It is recommended to use a soldering iron
with temperature control, as it protects the tip and enables better
connections. Clean the tip when solder rolls off.

For some projects, a basic multi-meter may be required or
handy.

Note: Always look for possible last-minute manual updates
indicated as ‘NOTE’ on a separate leaflet.

2. Soldering Hints:

Mount the component against the PCB surface and carefully
solder the leads.
Make sure the solder joints are cone-shaped and shiny.
Trim excess leads as close as possible to the solder
joint.

Note: Do not blindly follow the order of the components on the
tape. Always check their value with the parts list.

3. Construction:

1. Assembly (Skipping this can lead to troubles ! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully.

1.1 Make sure you have the right tools:

· A good quality soldering iron (25-40W) with a small tip.

· Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called `thinning’ and

will protect the tip, and enables you to make good connections. When solder rolls off the tip, it needs cleaning.

· Thin raisin-core solder. Do not use any flux or grease.

· A diagonal cutter to trim excess wires. To avoid injury when cutting excess leads, hold the lead so they cannot

fly towards the eyes.

· Needle nose pliers, for bending leads, or to hold components in place.

· Small blade and Phillips screwdrivers. A basic range is fine.

) For some projects, a basic multi-meter is required, or might be handy

1.2 Assembly Hints : · Make sure the skill level matches your experience, to avoid disappointments. · Follow the instructions carefully. Read and understand the entire step before you perform each operation. · Perform the assembly in the correct order as stated in this manual · Position all parts on the PCB (Printed Circuit Board) as shown on the drawings. · Values on the circuit diagram are subject to changes, the values in this assembly guide are correct* · Use the check-boxes to mark your progress. · Please read the included information on safety and customer service
* Typographical inaccuracies excluded. Always look for possible last minute manual updates, indicated as `NOTE’ on a separate leaflet.
1.3 Soldering Hints :

1. Mount the component against the PCB surface and carefully solder the leads

2. Make sure the solder joints are cone-shaped and shiny

3. Trim excess leads as close as possible to the solder joint

DO NOT BLINDLY FOLLOW THE ORDER OF THE COMPONENTS ON THE TAPE. ALWAYS CHECK THEIR
