Proster Multi Test Leads Kit (Model PST175b) Instruction Manual

1. Safety Information

Always observe basic safety precautions when using electrical test equipment to reduce the risk of fire, electric shock, or personal injury.

• Rated Category: This test leads kit is rated CAT III 1000 V, 20 A. Ensure your multimeter and application match or are below these ratings.
• Inspect Before Use: Before each use, inspect the test leads and accessories for any damage, cracks, or exposed wiring. Do not use if damaged.
• Proper Connection: Always connect the common (black) test lead first, then the live (red) test lead. When disconnecting, remove the live (red) test lead first, then the common (black) test lead.
• Insulation: Ensure all connections are fully insulated to prevent accidental contact with live circuits.
• Avoid Contact: Do not touch the metal parts of the probes or clips when connected to a circuit.
• Use Correctly: Use the appropriate test lead and accessory for the specific measurement and voltage/current level.

3. Setup Instructions

Attaching Test Probe Tips

The test leads feature removable tips, allowing for various testing scenarios. To change a tip:

1. Gently pull off the existing probe tip or protective cap from the test lead.
2. Select the desired replaceable tip (e.g., needle tip, banana plug, spade plug).
3. Firmly push the new tip onto the end of the test lead until it is securely seated.
4. Ensure a snug fit to maintain proper electrical contact and safety.

4. Operating Instructions

Connecting to a Multimeter

The main test leads connect to your multimeter via standard banana plugs. Insert the black lead into the 'COM' (common) jack and the red lead into the appropriate input jack for your measurement (e.g., 'VΩmA' for voltage, resistance, or current).

Using Different Attachments

The kit includes various attachments for different testing needs:

• Alligator Clips: These clips provide a secure, hands-free connection to terminals or wires. Simply attach them to the probe tips or banana plugs.
• Mini Spring Test Hook Clips: Ideal for connecting to small components or wires where a delicate, yet firm, grip is needed.
• Banana Plugs & Spade Plugs: Use these for connecting to banana jacks or screw terminals, respectively.
• SMD Patch Test Clip: Designed for testing surface-mount devices on circuit boards, offering precision and stability.

5. Maintenance

• Cleaning: After each use, wipe the test leads and accessories with a clean, dry cloth to remove any dirt, dust, or residue. Do not use abrasive cleaners or solvents.
• Storage: Store the test leads kit in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided carrying case to keep all components organized and protected.
• Inspection: Regularly inspect the leads for any signs of wear, cuts, or damage to the insulation. Replace any damaged components immediately to ensure safety and accurate measurements.

6. Troubleshooting

• Inaccurate Readings: Ensure all connections are secure and clean. Check that the correct test lead tips are used for the measurement. Verify your multimeter settings are appropriate for the circuit being tested.
• No Reading/Open Circuit: Check for continuity in the test leads themselves by touching the tips together (if your multimeter has a continuity function). Ensure the leads are fully inserted into the multimeter and the circuit points.
• Damaged Leads: If any part of the test lead or accessory is visibly damaged (e.g., frayed wire, cracked insulation), discontinue use immediately and replace the affected component.
