How to use a Volt Stick Sound

The Volt Stick Sound is a 230v AC non-contact, instant voltage checker featuring both red LED indicator and sounder, for added confidence when checking for the presence of an AC voltage.

What is a Volt Stick Sound?

It is a non-contact instant voltage tester for safely checking for the presence of an AC voltage. This model is similar to our orhiginal 230Y version, but with the addition of a buzzer indicator for increased peace of mind.

What do the markings on the Sound refer to?

  • IP64 rating - This means the Volt Stick can be used in the rain but not submerged underwater.
  • CE & IEC - This means the Volt Stick is relevant to all electrical safety and environmental standards.
  • CAT IV 1000VAC - This means the Volt Stick has an over-voltage safety rating and 1000 volts in a cat IV zone.

What is the VoltStick Sound used for?

Just the size of a pen, the Volt Stick Sound provides a visual red LED and sounder indication where a live voltage is detected in conducting materials - which may be either exposed or insulated.

The Volt Stick Sound is an ideal tool for an electrician to keep with them at all times so they can check for voltages in:

  • Cables
  • Sockets
  • Junction boxes
  • Fuse boards

Safety feature of the Sound:

One of the main safety features of the Sound - and, in fact, the whole Volt Stick range - is that there is no on/off switch. Therefore, all VoltStick devices are always ready to use and there is no way you will forget to switch it on.

Checking your Volt Stick Sound is functioning correctly before use

Before you use the Volt Stick Sound you must test to make sure it is working correctly. The best way to check the Volt Stick is against a known live source in the area you are about to work; this could be a switch or a flex to an electrical appliance.

How to test a voltage checker against an electrical socket

The SOUND is designed with a sensitivity that makes it possible to indicate live and neutral. When the Volt Stick buzzes and lights up red, this means a voltage is detected. If there is no light/sound this means there is no voltage detected. Remember to make sure you hold the Volt Stick behind the safety guard when using and testing it.

Test your voltage indicator against a known live source...

How to test the SOUND against a light switch

1. Switch the light switch on and move the Volt Stick Sound around the switch until it illuminates.

2. Turn the light switch off and the Volt Stick should also turn off. This means your Volt Stick is working!

How to test the Volt Stick Sounds against the flex of an electrical appliance

As the SOUND is very accurate and designed to detect 230 volts from 4mm, it is important you check the whole way around the flex. The Volt Stick indicators will go on and off as it moves further and closer to the live.

Once you have confirmed your Volt Stick is working, you can repeat the procedure on what you need to test. It is recommended once you have finished testing to double check the Volt Stick once again on that known live source to make sure it is still working correctly.

Why is my Volt Stick not giving me the results I expected?

If the results from your Volt Stick are not what you expected - make sure the batteries are working and replace them if necessary. It is good practice to regularly check  and replace the batteries, it is also good to remove the batteries from the Volt Stick when it is not going to be used for some time.
