Grounding Tester Kit — How to Use It

By the Naturalive team · Updated 9 September 2026

What's in the kit?

• Socket tester — plugs into a 3-pin socket and shows whether it's wired correctly, earth included
• Conductivity tester pen — lights when both tips rest on conductive material

Why two testers?

A grounding product only grounds you if two things are true at once: the socket's earth must be live, and the product's conductive material must conduct. Each tester proves exactly one, and cannot see the other. A pen will light on a perfectly conductive sheet that's plugged into a socket with a broken earth; a socket tester will pass a perfect socket with a softener-coated sheet plugged into it. Run both, and you know. For anyone who wants to see grounding on their own body rather than infer it, a multimeter is the third level — see below.

How do I use the socket tester?

1. Plug it in to the socket you intend to use, and switch the socket on — the tester needs power to read the wiring, even though your grounding product later won't.
2. Read the lights. Match the pattern to the legend printed on the tester. The row marked correct means live, neutral and earth are all wired properly.
3. If it shows a fault — typically "earth missing" or "open earth" — don't use that socket for grounding. Try another; most homes have several that pass. If every socket fails, WhatsApp us a photo; a grounding rod to real soil is the usual answer.
4. Unplug and switch off. The socket tester's job is done; it isn't part of the grounding setup.

How do I use the conductivity pen?

1. Know where to touch. On a mat, yoga mat or topper, the whole surface conducts — anywhere works. On a sheet or pillowcase, only the fine silver thread lines woven through the cotton conduct: both tips must rest directly on a silver line. The plain cotton between the lines stays dark, and that's normal.
2. Hold the pen normally and rest both tips on the material for a second. It lights: the material conducts.
3. On sheets, test a second line — near the stud and far from it — to confirm the grid conducts throughout.
4. Repeat monthly, and after every new detergent or cleaner.

What if the pen doesn't light?

A dark pen means one thing: the spot under its tips isn't conducting. It says nothing about the socket.

1. On fabric: both tips on a silver line? This is the cause nine times out of ten. Find a line and try again.
2. The material is coated. Fabric washed with softener, bleach, fragrance or essential oils — wash twice in plain detergent. A mat wiped with an oil-based cleaner — wipe with plain water. Dry, test again.
3. The stud. Touch the pen to the product's metal stud. Lit there but not on the material confirms coating.
4. The pen. If it lights on nothing, not even the stud, message us; we'll replace it.

How do I prove I'm actually grounded?

The two testers prove the setup. To measure grounding on your body, use a multimeter set to AC volts: one probe to the earth (through the adapter's earth connection), the other held between your fingers. The reading is the voltage your body carries from the electrical environment around you. Now touch the connected sheet or mat with bare skin: the reading falls toward zero. That drop, seen on a meter, is grounding — not inferred, measured. It's what we demonstrate on our Lives, and we're happy to walk you through it over WhatsApp.

Frequently asked questions

Why does the pen only light on some parts of my sheet?

Because only the silver thread lines conduct. The pen needs both tips directly on a line; the cotton between lines stays dark. On a mat, the whole surface lights.

Does the pen prove I'm grounded?

No. It proves the material conducts. The socket tester proves the earth is present at the wall. Together they're the practical proof; a multimeter reading of your body voltage dropping is the definitive one.

Do I need the kit if a pen came with my sheet?

The pen checks the product. The kit adds the socket tester, which checks the earth the product relies on — the half the pen can't see.

Can the socket tester damage anything?

No. It draws a trivial current to light its lamps and has no effect on the wiring.
