FAQs

What is the maximum voltage this tester can handle?

The Gunson Low Voltage Circuit Tester is designed for systems up to and including 48 volts.

Do I need to install batteries?

No, the tester is powered directly from the electrical system you are testing, so no batteries are required.

Can I use this tester on AC circuits?

No, this tester is specifically designed for DC (Direct Current) circuits only.

What does 'polarity insensitive' mean?

It means the tester will function correctly regardless of whether you connect the probe to a positive or negative voltage source.

How does the shrouded probe help?

The partial shroud on the probe reduces the risk of accidentally touching other components or conductors, which could cause a short circuit.

What is the cable length?

The cable length is approximately 90mm.

How do I know if the tester is working correctly?

You can test it on a known live circuit within the 6-48V range. If it indicates power, it is functioning. If not, check your connections or the tester itself.

Troubleshooting

Tester does not indicate power, but circuit should be live.

Ensure the probe is making good contact with the conductor. Verify the circuit is indeed within the 6-48V range. Check for any damage to the tester's probe or cable. Test on a known live circuit to confirm the tester is functional.

Tester indicates power, but the connected device does not work.

This tester only indicates the presence of voltage, not the quality or amperage of the supply. The issue may lie with the device itself, a poor connection further down the circuit, or insufficient current capacity.

Probe tip appears damaged.

Discontinue use immediately. A damaged probe can lead to inaccurate readings or short circuits. Replace the tester if the probe is compromised.

Pros and Cons

Pros

  • No batteries required, always ready to use.
  • Minimizes risk of accidental shorts due to shrouded probe.
  • Works on both positive and negative connections.
  • Suitable for a wide range of low-voltage automotive and electronic systems.
  • Simple and intuitive operation.

Cons

  • Limited to 48 volts; not suitable for higher voltage systems.
  • Cable length is relatively short (90mm).
  • Basic functionality, does not provide voltage readings.
  • Potential for damage if used on higher voltage systems.

Setup, Compatibility & Care

Setup: No setup is required. Simply connect the tester's probe to the circuit you wish to test.

Compatibility: This tester is designed for use on DC systems operating between 6 volts and 48 volts. It is not suitable for AC circuits or DC systems outside this voltage range.

Care:

  1. Keep the probe tip clean for accurate readings.
  2. Store the tester in a dry place away from extreme temperatures.
  3. Avoid using the tester on circuits exceeding 48 volts, as this can damage the tool and potentially cause hazards.
  4. Inspect the probe and cable for any signs of damage before each use.
